Hi,
I am trying to upload the program in Arduino Adafruit feather with Doorji(sx1278)LoRa module .it will upload but can't able to send the data to gateway. so i will check the Serial monitor only starting... only printed .How i can solve this issue .

Thanks in advance.

Good day,

I can make working the library with a Adafruit MO Lora
I configured my pin as the following

lmic_pinmap pins = {
  .nss = 8,			// Connected to pin D10
  .rxen = 0, 			// Needed for NiceRF Lora1276. Not needed for RFM92/RFM95
  .txen = 0, 			// Needed for NiceRF Lora1276. Not needed for RFM92/RFM95
  .rst = 4,  			// Needed on RFM92/RFM95? (probably not)
  .dio = {3, 5, 6},		// Specify pin numbers for DIO0, 1, 2
						// connected to D4, D5, D7
};

I would like now to use a Adafruit MO adaloger with a Radio Featherwing but I do not how and what on my above configuration

Adafruit provide a How To with this configuration

The poblem, it's not the same as my above configuration

I suppose but not sure, I should configure as the following for a Feather MO adalogger with a featherwing

lmic_pinmap pins = {
  .nss = 10,			// Connected to pin D10
  .rxen = 0, 			// Needed for NiceRF Lora1276. Not needed for RFM92/RFM95
  .txen = 0, 			// Needed for NiceRF Lora1276. Not needed for RFM92/RFM95
  .rst = 11,  			// Needed on RFM92/RFM95? (probably not)
  .dio = {3, 5, 6},		// Specify pin numbers for DIO0, 1, 2
						// connected to D4, D5, D7
};

But what about DIO?
I am not sure, but I sggest that I also have to wire as showed here

Someone has an experience with FeatherMO adalogger with Radio Featherwings?

Many thank for your help

Hello

I saw a connection between io2 to pin 5 and io1 to 6. Why these connections are used?
Can i use other pins not 5 & 6?

Thank you very much for your kind help

Hello, it's really nice of your clear instruction and code that makes it easy to test with the adafruit feather m0 lora boards.

Just a quick question in your code: I am not sure how you set the frequency of the end-node. Are they hidden somewhere or they are just pre-configurated to a certain frequency?

Helo
I am very new with Lora and I am trying to build a node with a Feather MO Lora board

I connect the pim has it's shown here

I also download the library LoRa-LMIC-1.51 as it's written here , and then I configured the code with

At TTN web site I created a new devise and I saved it as the following
// LoRaWAN Config
// Device Address
devaddr_t DevAddr = 0x26011942; // TTN Device Address

// Network Session Key
unsigned char NwkSkey[16] = { 0x25, 0x64, 0x48, 0xC4, 0x39, 0x57, 0x84, 0x89, 0x57, 0x33, 0xCA, 0x80, 0xF0, 0xF4, 0xA1, 0xD8 }; // TTN Network Session Key
                            
// Application Session Key
unsigned char AppSkey[16] = { 0x9A, 0xCB, 0xE8, 0x23, 0x4D, 0xC5, 0xCB, 0x37, 0xDB, 0x33, 0x85, 0x28, 0xCD, 0x28, 0x16, 0x01 }; // TTN App Session Key

// LoRaWAN Application identifier (AppEUI)
static const u1_t AppEui[8] PROGMEM = { 0x70, 0xB3, 0xD5, 0x7E, 0xF0, 0x00, 0x64, 0x29 }; // TTN Application EUI

I upload my code and here is the print I got
(I add some debug point. All print starting with "DEBUG: ..." are debug I added into the code)

Beginning to send data
seqno 1: Battery: 4.24
LMIC_setTxData2
DEBUG: engineUpdate
DEBUG: End engineUpdate
dataSent2:0
seqno 1: Free Memory: 28735
LMIC_setTxData2
DEBUG: engineUpdate
DEBUG: End engineUpdate
DEBUG: engineUpdate
DEBUG: processDnData
DEBUG: onEvent
DEBUG: EV_TXCOMPLETE
DEBUG: engineUpdate
Sleeping for 92 seconds

But nothing is recorded into my TTN console even if I am close within 5km of a gateway.
How should I exactly configure my devise by TTN?

Into the sketch file, I also observed the followin initLoRaWAN() function;

Is there a way debug if the node joned the nearest gateway?
Is tere a way to have thr following funtion to return true or flase?
Is there a way to know if data has been recorded or not to TTN?
If I am on the train, does the node will send message to a gateway if the train through an area coavered by a gateway? Or does the node have to join first a gateway and a node can not move...

I thank a lot if you tell me more about Feather MO Lora board with the goal to send sensor measurement to TTN

Many thank
