I Need Help with Setting Up RAK3172 WisNode LoRaWAN Module for Custom Application

Hello guys… :wave:

I recently got my hands on a RAK3172 WisNode module to use in a custom IoT project. My goal is to build a low-power sensor node that can transmit data over a relatively long range, but I’m running into a few issues and would really appreciate any guidance.

Firstly, I am having trouble getting the module to communicate with the LoRaWAN network server. I’m using the RAK Serial Port Tool to send AT commands, but it seems like the module isn’t joining the network successfully. I’ve double-checked the Device EUI, App EUI, and App Key – all appear to be correct, but the join request still fails. Could this be related to my settings or is there something I might be overlooking?

Secondly, I am also trying to configure the module in sleep mode to conserve power, but I’m not sure how to set it up properly. The documentation mentions a few commands, but it’s a bit unclear on how to use them effectively for low-power consumption.

I also check this: https://forum.rakwireless.com/t/wistrio-lorawan-mode-tx-power-settinqliksense But I have not found any solution. Could anyone guide me about this? If anyone has experience setting up the RAK3172 for a similar use case or can share some tips, I’d be grateful! Any advice on optimizing the configuration or troubleshooting the connection issue would be fantastic.

Thanks in advance!

Welcome to the forum @Aliambere

Beside of the DevEUI, AppEUI, AppKey, you need to setup the correct band (US915, EU868, …).
I am guessing you have a gateway that is already connected to a LoRaWAN server?
All devices, RAK3172, gateway and LNS must be setup to the same band.
If using US915, there are in addition 8 subbands and you have to choose the same subband on all devices.

For low power mode, are you using the RAK3172 with it’s AT command firmware or are you running a custom firmware on it?
