I thought I'd try sending down a few bytes to the node and I see the attempt to transmit to the node it fails since it's on the wrong channel as the node. In this case, the node is 902300 SF9 and the gateway tries to send the downlink packet on channel 923300. Shouldn't it be the same channel or is there something in my node code which is supposed to listen on the other channel?

Gateway output looks like this:

rxpk 017ce200a020a6f42f0277b7 message {"rxpk":[{"rssi":-45,"stat":1,"modu":"LORA","rfch":0,"tmst":404545573,"datr":"SF9BW8

Dear @JaapBraam ,

I am trying your code on an ESP12E, so far so good, nodemcu firmware installed, files uploaded.
Since I have an SX1278 module (only low band ie. 433), I've modified the freq setting to 433175000.
Connections:
DIO0-ESP12E GPIO5 - Definition in code - 1
DIO1-ESP12E GPIO4 - Definition in code - 2
SCK - ESP12E GPIO14
MISO - ESP12E GPIO12
MOSI - ESP12E GPIO13
NSS-ESP12E GPIO16 - Definition in code - 0
Gateway registers with backend, and can see the regular stats messages.

But I don't see packets arriving from the node (RN2483, also configured for 433 band) to the gateway. Is this something that should work, or am I trying something that is not implemented? - yet :-)
Thanks. Cheers.

Is all that is required is change the local CHN array defnintion to run in US 915Mhz

local CHN={}
CHN[0]=chan(902300000,"LoRa",MC1.BW125)
CHN[1]=chan(902500000,"LoRa",MC1.BW125)
CHN[2]=chan(902700000,"LoRa",MC1.BW125)
CHN[3]=chan(902900000,"LoRa",MC1.BW125)
CHN[4]=chan(903100000,"LoRa",MC1.BW125)
CHN[5]=chan(903300000,"LoRa",MC1.BW125)
CHN[6]=chan(903500000,"LoRa",MC1.BW125)
CHN[7]=chan(903700000,"LoRa",MC1.BW125)
CHN[8]=chan(903900000,"LoRa",MC1.BW250)
CHN[9]=chan(904100000,"FSK" ,MC1.BW150)

or do I have to do something more.

I'm first time to establish the lorawan server,would you please provide some method related to your nice project and lorawan server？Great thinks.

I have set GW_LON="-73.21848210000002" in init.lua but in TTN gateway coordinates longitude is showing up as positive 73.21848210000002

Hi,

I have been working with the single channel gateway on Australian frequencies using this library. Its a fabulous piece of work that is helping many out there who are stepping into Lora.

I am able to send messages to TTN using ABP without any issues, but OTA does not work.Was anyone able to get this working for OTA.

From the logs i can see the transmit packet received buy the gateway from TNN (transmitPkt), so I assume the gateway is transmitting this. I have also adjusted the receive window on my node to sufficiently cover the transmit timeframe during both the windows, but still not receive by the node. It gets the Rxtimeout. 1st window at 5 seconds and second at 6 seconds.with max window time of 3 seconds.

For the node i am using this library https://github.com/Lora-net/LoRaMac-node I am using the nrf52 as the mcu.

Ive been tweaking and trying since a week, but unable to get OTA to work. Am I missing something? Can you please help?

Regards
Arif

I am not familiar with nodemcu and I just followed your steps.

I encountered a problems:
PANIC: unprotected error in call to Lua API (bad argument #1 to '?' (number expected, got nil))

and the nodemcu restart over and over. and I am confused.

Hi there,

I can´t connect the pins of ESP8266 to the SX1278 as you described.

on my Ai-thinker esp8266 12-e GPIO 13 is connected to GND, otherwise it will not boot up.
where in the Lua files i can change the GPIO 13 to GPIO02 ?

thanks for reply
best regards from Lorch / germany

Robert

Thanks for this Gateway.
I would like to know if it will work also with ESP32?
Thank you.

It would be great if the ID could be made available, similar to https://github.com/tftelkamp/single_chan_pkt_fwd/blob/master/main.cpp#L563 so I can register the Gateway in the TTN frontend and see when my test messages pass through successfully.

Is it possible to connect the gateway to ttn-router-eu?
I would like to register my gateway to ttn

Can I assume
LoRa Gateway | Register Name |
---|---|---
GW_HOSTNAME | Gateway ID |
GW_ROUTER | ttn-router-eu |
| | Description | LoRaWanGateway SF12 and SX1276
??? | | Gateway Key

Where can I set the provided Gateway Key?

Hi, I'm receiving data from my test node:

rxpk 01f0db005ccf7ff42f2cd6be message {"rxpk":[{"rssi":-42,"stat":1,"modu":"LORA","rfch":1,"tmst":14490442,"datr":"SF7BW125","lsnr":8,"time":"2017-03-01T19:40:00.616803Z","codr":"4/5","data":"QNwSASYAAAABJPwj/fGgDeYDZRmgqqGoJbQ=","freq":868.100,"chan":0,"size":26}]} length 240

but nothing appears on TTN console.

I have a ESP8266 (NodeMCU "V3" from LoLin) with an RFM95 breakout board (with RF96 chips and wire based antenna).

For the node, I am running with an Arduino Mega with the MultiTech mdot.

I am testing in the same room, so there shouldn't be much issue with range.

I have set both the gateway and the node to use channel 0, and 913600000, but the mdot is failing to join the gateway.

On occasion I get some messages showing up on the console of the gateway:

rxpk 01e6cd005ccf7ff42f871543 message {"rxpk":[{"rssi":-106,"stat":1,"modu":"LORA","rfch":1,"tmst":221788462,"datr":"SF10BW125","lsnr":-10,"time":"2017-04-07T08:20:34.707863Z","codr":"4/5","data":"AOARANB+1bNwqKsAAAAAgABjTLhVchE=","freq":913.600,"chan":0,"size":23}]} length 241

I'm not sure whether it is something wrong in my setup, so apologise in advance if this is a newbie error.

while loading lua files I got some warnings see attached zip.
After several restarts I got the following message.

Hi again!
I use loraserver the - "lora gateway bridge 1.1.5" and i have the following error

It seems that the format that the gateway sends it is wrong.

Some 'cosmetic' changes:

Maybe in a next version you can add a few extra status messages. When I first started the gateway, it seemed it wasn't responding, but then I realised it just couldn't find the wifi network. A message telling that the device is trying to connect to the network would be nice.

Same for the radio module: the software does tell you when an unknown radio is found, but not when a known radio is found. Same confusion: I thought the module had freezed, but it actually worked like a charm.

I have the lorawan-server( https://github.com/gotthardp/lorawan-server ) on my machine and for some reason the LoRaWanGateway will not negotiate a join with that backend server. I can use the same arduino-lmic single channel code against the lorawan-server with a MultiTech MTAC gateway and full up standard OTAA works with the MTAC gateway. But when I turn the MTAC off and power up the LoRaWanGateway, I don't see it ever joining.

I did notice that with the MTAC it wants to join on Channel 65(dn2Chnl) in both single channel and multi-channel configuration. But even setting LMIC.txChnl=65 in the Join-failed switch/case does not help the LoRaWanGateway complete a join request.

Any ideas why this might work fine against TTN backend but not the local lorawan-server backend even though that backend works with the MultiTech MTAC gateway?

hi,
Thanks for your single channel lorawan gateway, especially the ideal of CAD with scanning SF. It cause my arouse my interest. but I find problems as follow:
The packet loss rate is pretty high, if CadDetected but receive packet failed, the time wasted will influence the following SF scanning procedure. It will cause packet loss. I do not know why The SF12 packet can cause the other SF CadDetected ? and the transmit payload also cause CadDetected.
rx timeout 7 0 rssi 50
rx timeout 8 0 rssi 45
Looking forward to your suggestion. Thanks a lot

Using PuTTy under Windows 7 I have a problem with CONFIG.print() shows the current configuration

I also probe CONFIG.GW_HOSTNAME="LoRaWan_Dock_v1_1" and CONFIG.GW_NTP_SERVER="fr.pool.ntp.org" but I dont really know if the parameter was updated.

any idea about this?

Hi JaapBraam,

First of all, very nice work!
It's not an issue but a question.
Can I change the wifi configuration without using a serial connection ? This will be nice if the gateway ins installed inside a closed box or in a inaccessible place.

Seems that the dev branch is missing CJSON, while the master branch now has it

At https://nodemcu-build.com

Docs might need update?

By adding CONFIG["GW_TZOFFSET"] = "-8" for PST and crate a localtime function instead of gmtime using this offset times the 3600(num sec in 1 hour). Currently get error though.

local function localtime(t,us)
-- HOW TO DO THIS? rtctime.epoch2cal doesn't like my "fixed" epoch time
local lt = t + CONFIG["GW_TZOFFSET"] * 3600
local tm = rtctime.epoch2cal(lt)
return string.format('%04d-%02d-%02d %02d:%02d:%02d GMT',tm["year"],tm["mon"],tm["day"],tm["hour"],tm["min"],tm["sec"])
end

My node are using LMIC code and transmitting to ESP gateway.. Setup US-915 channel sub band 0, 0-7 and enable channel 0 only. The freq received is different compare what I got if using Raspi Single packet gateway source. Below are the rcd packet;

rxpk.017f1000600194ffff0b94cb.message.{"rxpk":[{"rssi":-105,"stat":1,"modu":"LORA","rfch":0,"tmst":61998373,"datr":"SF10BW125","lsnr":-2,"time":"2016-08-20T02:28:08.167523Z","codr":"4/5","data":"QMSAzwYAVAEOGm77NG9CjwcPdOph","freq":902.299987,"chan":0,"size":21}]}.length.238

Followed the procedure and it's working again.

I tried the new code(didn't change firmware though) and it seems to have a problem activating. After telneting in it looks ok but from a minicom console I'd previously seen a non 902.3MHz freq listed.
Here's the telnet output upon connecting:

only very rarely messages are transmitted - is there something that might have changed on the TTN side? Or did I do something else wrong when setting it up?

Hi,

Thanks for the amazing gateway. I did everything, but my gateway is not running. Tried to run
dofile("init.lua")

On Esplorer I uploaded:
init.lua
LoRaWanGW.lc
SX1276.lc

And then it dont print anything. Tried to include some prints at the end and beginning.

I'm quit new to nodemcu. I dont get errors only:
ntp synced using 89.xx.20.xx

Also have my Slave select on pin D8, so I changed in SX1276.lua:
gpiowrite(8, 0)
Maybe we can I can put it in init.lua, so we can choose the SS pin...

Any solutions to debug??

Add NTP server to the Config.lua file and change in LoRaWanGW.lua

CONFIG["GW_NTP_URL"]="nl.pool.ntp.org"

Accessing telnet via putty or mobaxterm gives an output unformatted (seems that the lines are too long or without line end). See picture attached.

It works, buts it´s difficult to read.

I am trying to build a single channel lora gateway with a Lorago dock v1.1 board(ESP8266 and SX1276) and trought ttn I arrived to this repository. It seems exactly what I want, but, I found some problems:

• I am uploading lua files with ESPlorer tool, because I dont know how python works very well... Should have I a problem using this tool?

• I gave 4 "succes uploading" (one for each lua file in src folder), but when I reset the board I get:

"Node custom build by....... ......no config found, use default values" ... and nothing else...

any idea? thank you in advance!

I have a bunch of LoRa Single Channel Gateway by Hallard(https://github.com/hallard/WeMos-Lora) and would love to get full spread factor support. But the Hallard board and WeMos have DIO0 and DIO1 OR'ed through diodes to one pin on the WeMos. Would it still work?

So far I don't see any node messages going through to TTN and don't see anything on the console from the gateway but this:

I'm using US freq and inserted them as you mentioned while commenting out the EU freqs. My nodes are on ch0( 902300 and SF7 ).

UPDATE: Setting DIO0 and DIO1 to 8(D8) in init.lua and uploading I now see some scrolling data on the console. Still not getting messages through to TTN but it's something and when I force the node to transmit I see the rssi signal jump from ~55 to 119 so it's seeing something.

rx timeout 7 0 rssi 55 -- actually fluctuating

Is there problem connecting to TTN? The data is not transmitted to TTN. In the log i see that the gateway receives frames.

Hi JaapBraam，I am coming again
When I set parameter GW_SF to a specific value(like SF10), the gateway can receive 100% ok，
But when I set the parameter GW_SF to ALL, the gateway mostly prompts "rx timeout", only about 20% can receive the data.So I want to know what about you reality test and if there are any advise for me to deal this problem
Great thank to you！！！

Gateway receives uplink ok at 865062500 but then transmits an ack at 865620000 when it should be the same as the Uplink frequency.

Could be misinterpreting the ack request from the LoRaWAN server as the same end node communicates with an 8+1 channel gateway (mcard on RPi) using the same router, exact same configuration, with no problem, i.e. 86506250 up and down.

This router is Orne Brocaar's LoRaWAN server, latest version.

Here's some output from the ESP8266 gateway via telnet:
rxpk 0176c600a020a6f42f19ff48 message {"rxpk":[{"rssi":-91,"stat":1,"modu":"LORA","rfch":1,"tmst":1590172565,"datr":"SF12BW125","lsnr":7,"time":"2017-10-28T22:54:58.558062Z","codr":"4/5","data":"gAEBAQGACgAPSO+NYWcB0v7UWQ==","freq":865.062,"chan":0,"size":19}]} length 235

txpk_ack {"txpk_ack":{"error":"NONE"}}
transmitPkt 16598 12388 -1 865620000 192 112 2 64 27 12

If I'm reading this correctly the LoRaWAN server request is 865.062 but actual transmission is 865.620.

Spectrum analyser indicates these frequencies are indeed being transmitted.

Probably a while since you've looked a this! So any suggestions would be appreciated.
Cheers, Ron

Hi,

I installed your gateway and it makes contact with TTN as it should, it doesn't receive Lora messages. I am using a RF 95 module. I have been told it should be compatible with the SX1276, but I am wondering whether that's actually true?

I get this message after starting:

> got ip	192.168.43.93	255.255.255.0	192.168.43.1

Unknown radio: 	9

So the radio is 'unknown'...

Should I get a 'real' SX1276 instead of the RF 95?

Hello,

I have the gateway up and running. It is forwarding the packets sent by the node to the TTN server and I can see them in the console. However, it seems that when the node sends a confirmed packet, the ack coming from the server does not reach the node. I can see that the gateway receives and apparently forwards the ack. I have also tried to simulate a downlink from the TTN console and seems to be working. I can't really see if what the gateway forwards is the simulated packet or something else because it is encrypted. Nevertheless, the address of the node is correct in both case. But I can't see the node receiving anything back (looking at the serial port of the node).

This is the output of the gateway:

rxpk 0142aa00600194f42f10187b message {"rxpk":[{"rssi":-42,"stat":1,"modu":"LORA","rfch":1,"tmst":2060746683,"datr":"SF7BW125","lsnr":9,"time":"2017-03-09T06:54:13.361317Z","codr":"4/5","data":"gGcZAiaA8AAB//oKi+EvV/YMaUY=","freq":903.900,"chan":0,"size":20}]} length 234

txpk {"txpk":{"imme":false,"tmst":2061746683,"freq":923.3,"rfch":0,"powe":20,"modu":"LORA","datr":"SF7BW500","codr":"4/5","ipol":true,"size":13,"data":"YGcZAiYgiQABNX0/eg=="}}

txpk_ack {"txpk_ack":{"error":"NONE"}}

transmitPkt 11626 6461 -1 923300000 112 144 2 64 20 13

And this is from the node:

215627791: TXMODE, freq=903900000, len=20, SF=7, BW=125, CR=4/5, IH=0
Packet queued

215756338: RXMODE_SINGLE, freq=923300000, SF=9, BW=125, CR=4/5, IH=0
215896595: EV_TXCOMPLETE (includes waiting for RX windows)
Setting next callback
215902911: engineUpdate, opmode=0x800

I am using the LMIC-Arduino library developed by Matthijs Kooijman. Since I am not sure whether I'm doing something wrong on the gateway side or node side, I will also post this on his repo.

Thanks!

Hi Jaap,

I'm getting started trying out your project, and I have a (I'm located in USA, so I use a 915MHz version) Adafruit RFM95W LoRa Radio Transceiver . Is that ok? Do you recommend any particular unit?

I was unable to figure out which SemTech radio Adafruit is using for the above product.

Thanks for your help!

Best regards,

Forrest

I still have one of your gateways running(one of 4 here) and after having built a full multi-channel gateway I was doing some testing and fired up a node which I'd previously provisioned with OTAA code. I saw some strange messages on TTN data page and then realized it was the single channel node with OTAA I had setup long ago without any luck getting it to work. Low and behold your gateway picked it up on the same Freq and up on TTN it showed data.

Fantastic!

Thanks for the great testbed and this might be an option for attendees of my workshops as long as they expect to use their nodes close to their homes or offices. IIRC you said the range of this multi SF gateway was down to a few hundred meters.

You write in your goals "Add support for more than one channel (won't work :-( )". I'm curious as to why not and what your intended approach was.

When running local servers instead of going against TTN server it would be handy to be able to specify the port number in the Config.lua file instead of having to edit the number used in a few places.
