Version of RadioHead library for Teensy boards
Home Page: http://www.airspayce.com/mikem/arduino/RadioHead/
License: Other
This copy of RadioHead is modified for Teensy
Ths original RadioHead is available here:
When "#include <RH_RF95.h>" is used in the Arduino-IDE with the ESP8266 and any recent "https://github.com/esp8266/Arduino" code (eg.May19), the ESP8266 crashes at run-time at "RH_RF95.init()" with the message "ISR not in IRAM".
I succeeded in fixing this by editing the "RH_RF95.cpp" file, and changing following 3 lines:
from "void RH_RF95::isr0()" to "void ICACHE_RAM_ATTR RH_RF95::isr0()"
from "void RH_RF95::isr1()" to "void ICACHE_RAM_ATTR RH_RF95::isr1()"
from "void RH_RF95::isr2()" to "void ICACHE_RAM_ATTR RH_RF95::isr2()"
I understand that this is an issue for both the ESP8266 and the ESP32 (although I have not tested the ESP32).
I hope this info will be of use!
Just an FYI - this version seems to be out of date with the RadioHead on AirSpayce. Currently looking at straight forward changes that are available in the updates.
I use the RadioHead library on a Adafruit feather M0 RFM9X LoRA radio. I select 434 freq. I have several of those and they can talk to one another. I also have some RN2438 from Microchip
In this I have the following configuration:
sys reset
mac pause
radio set wdt 0
radio set pwr 13
radio set mod lora
radio set freq 434000000
radio set cr 4/5
radio set crc on
radio set bw 125
radio set sync 12
radio set iqi on
radio set sf sf7
radio tx 0123456789ABCDEF
This is to conform to default configuration after init:
Bw125Cr45Sf128 = 0, // < Bw = 125 kHz, Cr = 4/5, Sf = 128chips/symbol, CRC on. Default medium range
But the modules wont communicate. Is there some parameters I am missing in the RH_RF95 library?
Is Sf = 128chips/symbol the same as lora documents mean by "sf7"
/gh
I'm using this library on Teensy 3.2, but I want be able talk to my arm board(running linux).
Hello,
I was just compiling the RadioHead library for the Adafruit feather M4 and I am unable to compile as the library only supports the ATSAMD21's timers and not the ATSAMD51s. The problem is in RH_ASK.cpp on the fallowing lines-
#elif defined (__arm__) && defined(ARDUINO_ARCH_SAMD)
// Arduino Zero
#define RH_ASK_ZERO_TIMER TC3
// Clock speed is 48MHz, prescaler of 64 gives a good range of available speeds vs precision
#define RH_ASK_ZERO_PRESCALER 64
#define RH_ASK_ZERO_TIMER_IRQ TC3_IRQn
// Enable clock for TC
REG_GCLK_CLKCTRL = (uint16_t) (GCLK_CLKCTRL_CLKEN | GCLK_CLKCTRL_GEN_GCLK0 | GCLK_CLKCTRL_ID(GCM_TCC2_TC3)) ;
while ( GCLK->STATUS.bit.SYNCBUSY == 1 ); // wait for sync
// The type cast must fit with the selected timer mode
TcCount16* TC = (TcCount16*)RH_ASK_ZERO_TIMER; // get timer struct
TC->CTRLA.reg &= ~TC_CTRLA_ENABLE; // Disable TC
while (TC->STATUS.bit.SYNCBUSY == 1); // wait for sync
TC->CTRLA.reg |= TC_CTRLA_MODE_COUNT16; // Set Timer counter Mode to 16 bits
while (TC->STATUS.bit.SYNCBUSY == 1); // wait for sync
TC->CTRLA.reg |= TC_CTRLA_WAVEGEN_MFRQ; // Set TC as Match Frequency
while (TC->STATUS.bit.SYNCBUSY == 1); // wait for sync
// Compute the count required to achieve the requested baud (with 8 interrupts per bit)
uint32_t rc = (VARIANT_MCK / _speed) / RH_ASK_ZERO_PRESCALER / 8;
TC->CTRLA.reg |= TC_CTRLA_PRESCALER_DIV64; // Set prescaler to agree with RH_ASK_ZERO_PRESCALER
while (TC->STATUS.bit.SYNCBUSY == 1); // wait for sync
TC->CC[0].reg = rc; // FIXME
while (TC->STATUS.bit.SYNCBUSY == 1); // wait for sync
// Interrupts
TC->INTENSET.reg = 0; // disable all interrupts
TC->INTENSET.bit.MC0 = 1; // enable compare match to CC0
// Enable InterruptVector
NVIC_ClearPendingIRQ(RH_ASK_ZERO_TIMER_IRQ);
NVIC_EnableIRQ(RH_ASK_ZERO_TIMER_IRQ);
// Enable TC
TC->CTRLA.reg |= TC_CTRLA_ENABLE;
while (TC->STATUS.bit.SYNCBUSY == 1); // wait for sync
Does anyone have the correct file that could be used with the M4? In case you need the compilation error-

Thank you,

I'm working on a project using LoRa module Ra-01 Ai-thinker which is operating at 433 Mhz connected to an Arduino Nano.
i used the example codes in RH_RF95 to transmit and receive data between 2 nodes.
However i only can achieve a range of approx 30meters.
Anybody can help me out how can i achieve further range?
Tried adjusting the transmitting power still but still no improvement.
What I am doing is that:
-Sender will send "on/off" or "blink" to turn on/off or blink the receiver's LED
-Receiver receives data from sender and turns on/off or blink LED
-Then it sends back an acknowledgement back to the sender
Sender code

hello,
i have a boring problem with a webserver running on nodemcu 1.0 using ask_reliable_datagram_client. i identified this codeline to stop the server working ...
**dtostrf(gTemp, 10, 2, reinterpret_cast<char *>(&data));**
data[0] = 'T';
manager.sendtoWait(data, sizeof(data), ServerAdr);
i tried several options to bring "data" into uint8_t dataformat with different succes - from immediate crash till some hours of working. if i comment out the dtostrf the server works well again (also sprintf does not work).
have somebody an idea why this happens?
best regards
andreas
Hello,
I have a use case that would require me to potentially have an address space larger than 8 bits. Is there any method for accomplishing this functionality using this library?
Also, is there any known technique for allocating addresses without collisions or hard-coding the addresses into firmware.
Any help much appreciated - and thank you for your work on this library,
Andrew
this is what is causing the problem
#include <SPI.h>
#include <RH_RF22.h>
#include <Servo.h>
this is what error i've got:
libraries\Servo\avr\Servo.cpp.o (symbol from plugin): In function `ServoCount':
(.text+0x0): multiple definition of `__vector_11'
libraries\RadioHead\RH_ASK.cpp.o (symbol from plugin):(.text+0x0): first defined here

Error compiling for board Arduino Pro or Pro Mini.
I am sure after a week of trying that wires are correctly connected proper voltage (3.24V ) and capacitor 10uF is connected to nrf24. same circuit with pro mini is working as server and client.
Now I am trying to upgrade my project to teensy 3.1 and it fails in init() at
if (spiReadRegister(RH_NRF24_REG_1D_FEATURE) != (RH_NRF24_EN_DPL | RH_NRF24_EN_DYN_ACK)){
return false;
wiring is proper for sure.
I have tried all possible things for now.
my arduino is 1.6.3 and teensyduino 1.23.
Hi ,
I wanted you to tell me how can I solve this problem
which I send my data from master like 5 times
but in slave or client the receive is 4 time then when you send the sixth (from master)
the receiver shows the 5th,
I appreciate if you help me,
thanks lot,
I did not manage to get the example rf69_server working.
It hangs in void RH_RF69::setOpMode(uint8_t mode)
at
// Wait for mode to change.
while (!(spiRead(RH_RF69_REG_27_IRQFLAGS1) & RH_RF69_IRQFLAGS1_MODEREADY)) ;
Strange thing is, receiver works, and if I merge receiver and sender to the same ino and let them run on the same Arduino uno, than it works.
Switching to lowpower lib examples works straight.
Something is wrong. I wonder that I´m the only one.
I made some test with two very short programs (based on your examples!) on the feather... the dont have the same ENCRYPTION KEY but the receiver is still getting frequently messages from rf69_manager.available() ! Whats wrong here! Huge problem !!
Last hex on the TX and RX are different!

On the mentioned line the interrupt pin is set as an input. This happens after attaching the interrupt to the pin. On the TeensyLC I tested with, this caused the interrupt to not work.
Fix:
Hi
I have problems with stable transmissions for the RFM69. Initialization seems to be fine, but when I transmit with _spRFM->send(_spData, 2) sometimes the call will never come back. It looks like the internal call waitPacketSend() is the reason. Does someone know what the reasons are for not returning from waitPacketSend? The comparison inside is while (_mode == RHModeTx). But what is responsible for not "leaving" the transmission-mode? Can it be that it is something like too much noise on the radio frequency or no receiver found? As far as I understand it is not a confirmed transmission, it is fire and forget?
Investigating further, it looks like the interrupt is not called. After that, the mode is for ever RHModexTX (which makes sense). The question is now, what can create such a scenario? Instable power supply? Some time the interrupt is fine, sometimes not.
Has someone an idea?
Kind regards

Hi!
I´m trying to get started with the library on a Nano Every but the interrupt attachments seem "unpopular" with the compiler. First I got this message:

Hi, there is a plan to use the CAD detection feature on the sx1276 modules to enable the detection on more the one channel?
Thanks guys
I am playing around with SX1296 modules connected to ESP8266's and found out that the interrupt handlers called within the various layers of drivers (RH95, various SPI layers, ...) are not ESP8266 interrupt safe (they do not have the ICACHE_RAM_ATTR).
I also had to modify Arduino's ESP8266 core SPI library as I also found this one "not interrupt safe".
For now, I have made my own mods and seem to now have a stable ESP8266 implementation (scope to RH95 for now).
Am I the only one to have met those issues?
If any interrest, I am happy to share the mods even if they are limited to RH95 support.
Hello, I am a student in Art & Technology and I would like to send OSCMessages (https://github.com/CNMAT/OSC) over RF95. Do you think I would be able to do this after adding some code to the RH_RF95.h and .cpp files?
working :)
Now I want to keep all of the packets received at the LoRa server or LoRa shield.
However, in current implementation of RadioHead, with enabling CRC, only packets that pass CRC check will be keeped.
I have tried my best to disable CRC but it can not work.
I have looked up from the datasheet sx1276_77_78_79 to find the register, and modify the corresponding value for RxPayloadCrcOn in RegModemConfig2(0x1E).
According to the description,
Enable CRC generation and check on payload:
0 -> CRC disable
1 -> CRC enable
If CRC is needed, RxPayloadCrcOn should be set:
Then it should be worked when I add a new function like this.
void RH_RF95::setCRCState(int8_t crcState)
{
spiWrite(RH_RF95_REG_1E_MODEM_CONFIG2, (spiRead(RH_RF95_REG_1E_MODEM_CONFIG2) & 0xfb) | ((crcState << 2) & 0x04));
}
According to the output from the serial, I have successfully modified the value of RxPayloadCrcOn from 1 to 0.
However, when I recompile the sketch of LoRa_client and LoRa_server.
The LoRa shield can not received the packets from the LoRa server anymore.
Therefore, how to disable CRC check correctly?
I am trying to create a simple TCP-like sending protocol by sending, waiting for an ack, and if no ack is received in a certain amount of time, try again.
I got it mostly working except for a frequent, but random occurring problem. The recipient will randomly miss a packet, but when the next packet is received, it receives the previous missed packet. I have tried clearing and flusing the rx buffer, but to no avail. It appears as if the rx queue is receiving it, but it cannot be detected until another packet is received.
Perhaps a packet is available, but available() is returning an incorrect value?
Here is thread from the arduino forum that mentions a similar issue:

Hello!
I working with LoRa on RH_RF95 and I would like to separate two networks which can works around self. I tried to make SyncWord but it not works (producer give me info about that).
I'm trying to add param "networkId" to RadioHead lib to check that packet is coming from network of my node. NetworkId is something like Address of node but it could make bigger grids in LoRa.
I know that I need to add 1 byte (networkId) to header of send packet and i know that i need compare byte in receive packet but I have problem with implement in this library.
Anybody can help me?
Best Regards!

Hello friends, this is first time I am using RH_NRF24.h, but as I try to upload code its say No such file or directory. So please help me to solve this issue, I am struggling a lot to solve this but I am stuck on it. PLEASE HELP ME TO SOLVE THIS AS SOON AS POSSIBLE.
Hi,
On ESP8266 I've got many warning regarding ntohs and htons redefined. This name is in conflict with ESP8266WiFi Library.
I've resolved renaming all ntoh and hton definitions to rh_ntoh and rh_hton in RadioHead.h lines1700-1720
It do not create new warning or error on compiling. Can you check if this mod can cause some other problems? I' was'nt able to find any occurrency about these names in whole library, so I supposed it is unused.
Tested RH_NRF24 with Arduino Maga.
The documentation says
/// For an Arduino Mega:
/// \code
/// Mega Sparkfun WRL-00691
/// 5V-----------VCC (3.3V to 7V in)
/// pin D8-----------CE (chip enable in)
/// SS pin D53----------CSN (chip select in)
/// SCK pin D52----------SCK (SPI clock in)
/// MOSI pin D51----------SDI (SPI Data in)
/// MISO pin D50----------SDO (SPI data out)
/// IRQ (Interrupt output, not connected)
/// GND----------GND (ground in)
/// \endcode
/// and you can then use the constructor RH_NRF24(8, 53).
But that does not work, as the file RadioHead.h sets "SS" in an incorrect way.
In the Arduino pins_arduino.h file you find (for the Mega)
#define PIN_SPI_SS (53)
#define PIN_SPI_MOSI (51)
#define PIN_SPI_MISO (50)
#define PIN_SPI_SCK (52)
static const uint8_t SS = PIN_SPI_SS;
static const uint8_t MOSI = PIN_SPI_MOSI;
static const uint8_t MISO = PIN_SPI_MISO;
static const uint8_t SCK = PIN_SPI_SCK;
So SS is a static const of type uint8_t !!!
In the file RadioHead.h SS is set with "#define", and you find
// Slave select pin, some platforms such as ATTiny do not define it.
#ifndef SS
#define SS 10
#endif
As a result, for the Mega, SS is defined as pin 10 :-( :-(
You can easily test this. A simple sketch
#include <SPI.h>
void setup() {
Serial.begin(115200);
Serial.println(SS);
}
void loop() {
}
shows correctly 53 on the Serial monitor, while
#include <RH_NRF24.h>
#include <SPI.h>
void setup() {
Serial.begin(115200);
Serial.println(SS);
}
void loop() {
}
shows 10 ! :-(
Work around : use pin 10 for SS and initialize as
RH_NRF24 nrf24(8, 10);
I am developing a custom network system using sx1278, and to use this driver i need to know the received message size, because there are many possible data streams.
Also, i am sending binary data, not text.
Already reviewed:
https://www.airspayce.com/mikem/arduino/RadioHead/classRHGenericDriver.html
And:
https://www.airspayce.com/mikem/arduino/RadioHead/classRH__RF95.html
Any idea?
Thanks 4 the great job!
Hi there,
I am using Radiohead library since 2015 and I love this library to use in my university project. I like to request the team of this library to add support for B-L072Z-LRWAN1 - STM32L0 Discovery kit. Its a great kit with in build sx1276 LoRa module with strong STM32L0 micro-controller. It would very nice if you could manage some time and add support for this kit (it is cost effective compared to other devices) .
Thanks in advance
Hello,
I'm struggling using the RH_RF95 with an ISR. I need to send a message when a pin's state change. But when the state change the serial is just freezing and nothing is sent. This issue disapear when I comment this line :
rf95.send(data, sizeof(data));
My interrupt PIN is 3 on Arduino Uno, could the issue come from here ? Or maybe it's not possible to use LoRa comm insisde ISR ? Thank you for your time !
Here is my code :
// I2C Master
// Include the required Wire library for I2C
#include <Wire.h>
#include <SPI.h>
#include <RH_RF95.h>
// Singleton instance of the radio driver
RH_RF95 rf95;
const byte interruptPin = 3;
void setup() {
Serial.begin(9600);
Wire.begin(); // Start the I2C Bus as Master
pinMode(BUZZER_PIN, OUTPUT);
pinMode(interruptPin, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(interruptPin), InterruptVol, CHANGE);
//Initialize LoRa Module
while (!rf95.init()) {
Serial.println("LoRa radio init failed");
while (1);
}
Serial.println("SETUP FINISHED !");
Serial.println("");
}
void InterruptVol(){
Serial.println("INTERRUPTION");
alerte = true;
if(digitalRead(interruptPin)){
SendAlertMessage(); // LoRa ne marche pas dans fct d'interruption
} else {
alerte = false;
noTone(BUZZER_PIN);
}
}
void SendAlertMessage(){
blabla...
SendLoraData(msgAlerte);
}
void SendLoraData(char data[]) {
Serial.print("[LoRa] Sending data... ");
data[strlen(data)]='\0';
//Serial.println(data); //debug
rf95.send(data, sizeof(data));
Serial.println(" Data sent ! ");
rf95.waitPacketSent(1000);
delay(1000);
}
On line 27 of the loop() functon of the ask_receiver.pde example sketch, there's a variable "i" declared that appears to serve no function:
int i;
No biggie, but for the sake of not confusing people thought it might be best to remove this!
Cheers.

Had no success connecting up pair of Arduino Due each with Duinotech XC-4522 RF433MHz modules. XC-4522 uses nRF905. Wired up as per the RadioHead example code instructions.
Eventually found this, claiming that the PWR pin was not connected or used in the Radiohead code:

So I did as they recommend and the example sprang into life.
I wired PWR to D7 on each Arduino and added a line of code right after successful init()

spiWrite(RH_RF95_REG_4D_PA_DAC, RH_RF95_PA_DAC_ENABLE);
power -= 3;
}
else
{
spiWrite(RH_RF95_REG_4D_PA_DAC, RH_RF95_PA_DAC_DISABLE);
}
// RFM95/96/97/98 does not have RFO pins connected to anything. Only PA_BOOST
// pin is connected, so must use PA_BOOST
// Pout = 2 + OutputPower.
// The documentation is pretty confusing on this topic: PaSelect says the max power is 20dBm,
// but OutputPower claims it would be 17dBm.
// My measurements show 20dBm is correct
spiWrite(RH_RF95_REG_09_PA_CONFIG, RH_RF95_PA_SELECT | (power-5));
}
}
The last line seems to not be correct, it should be (power-2) as Pout = 2 + OutputPower? I double checked with a LMIC library (LoRaWan) where they take (power - 2).
This is quite a serious bug and is on all RadioHead libraries on GitHub.

Error compile for board Generic STM32F103Z series.
I can't use the Servo library with Radiohead. I think it's an issue with the timers conflicting. How can I fix this?
Thanks
