RAK811 Wisnode Lora Module v1.2 with Arduino UNO NOT WORKING

Hi, I have tried to connect TTN with RAK811 Wisnode Lora Module v1.2 on Arduino UNO, but it dosen’t work. I have researched and didn’t find how to work well.
I configured the module according to the following process.
Have I mistaken connecting jumper wire on the board RAK811 Wisnode Lora Module v1.2?

  1. set RAK811 Wisnode Lora Module v1.2 according to the “Get_Start_with_RAK811_WisNode-LoRa.pdf”.
    - BOOT LOADER ver 3.0.2
    - firmware ver 3.0.12 HF (AS923)
    - the response from RAK SERIAL PORT TOOL is following.

  1. conected TTN successfully. (pic1,pic2)

  1. changed uart baud rate to 9600 by ATcmd “at+set_config=device:uart:1:9600”, no response but I could open COM PORT by 9600. (pic3)

  1. connected RAK811 Wisnode Lora Module v1.2 with Arduino UNO.(pic4)
    - P1 : jumping CTX <-> RXD, CRX <-> TXD. Is this wrong?

  1. downloaded “Arduino Library” from GitHub.
  2. uploaded “JoinNetworkOTAA” in “RAK811/Arduino Library/RAK811/examples/”.Of course I replaced DevEui, AppEui and AppKey in the code.
  3. uploaded successfully but couldn’t connect with TTN.(pic5)

Hi,I have exactly the same problem that describes @takisd
Any idea what might be happening.

Hi all,

It seems there are some issues on this usecase.
Actually, for the latest V3.x firmware, we haven’t tested it with Arduino, but i know it is important to support this usecase. So we will spend some time on it, and once we complete it, i’ll tell you ASAP.

hi @takisd,
I have made the module work. I tell you my experience.
After performing all the updates, as you describe it,
Make the following connection between the Wisnode and my arduino Uno

Thanks to the explanation of @zabeelr, in the following post https://forum.rakwireless.com/t/rak811-problems/49/9?u=ncl17

I realized that the existing libraries for arduino don’t work, since the AT commands and their responses have changed.
I have updated these libraries (rudimentary)

Another problem I encountered is the use of “softwareserial”, for being arduino Uno.
I have changed in softwareserial.h the value #define _SS_MAX_RX_BUFF 256, so that the response message is not cut.

I have added a basic example to the library, it also uses a DHT11 connected to pin 5, 5v and GND
send a payload with temperature, humidity and a random value

I hope you can understand since I don’t speak English very well
best regard!


Hello everybody I use the RAK811 WisDuo breakout and I have the same problem, when i open the serial monitor of the arduino i have this:

So i tried to use the procedure that said @ncl17 but i always obtein this, however my keys are correct

PLS refer to newest Arduino_WisNode Library:https://github.com/RAKWireless/WisNode-Arduino-Library
