RAK3272S +EVT:JOIN_FAILED_TX_TIMEOUT

Hi,

I have seen several posts regarding this issue however I have not been able to do anything to fix it on my board.

I have a RAK3272S Ver. C breakout board and I am unable to get it to connect to LoRaWAN using only AT commands.

I have tried many thing including:

  • Updating to the latest firmware using DFU
  • Updating to the latest firmware using STLink
  • Different combinations of DEVEUI, APPEUI, APPKEY
  • I have tried both AS923 and AS915 on different gateways

The LNS does not get any communications from the module and I’m not able to connect I just get the +EVT:JOIN_FAILED_TX_TIMEOUT error.

I am using the following AT Commands:

  • AT+NVM=1
  • AT+NJM=1
  • AT+CLASS=A
  • AT+BAND=8
  • AT+DEVEUI=X (leaving as default)
  • AT+APPEUI=X (have tried leaving as default, all 00 and others)
  • AT+APPKEY=X (Using the appkey I generate using the LNS)

I thought it might be an issue on my end so I have also tried the above commands on an RAK4630 WisBlock module and it worked straight away.

Any assistance would be appreciated.

Thanks
Brad

Welcome to the forum @Brad

What version of the firmware did you flash? Can you give me the result of AT+VER=?

Hi Bernd

Thanks for your response, see below I ran a couple of extras in case any of these help.

  • AT+VER= RUI_4.2.0_RAK3272-SiP
  • AT+APIVER =3.2.9
  • AT+CLIVER= 1.5.11
  • AT+BOOTVER= RUI_BOOT_0.6_STM32WLE5CC

Cheers

Which breakout board do you have? I am confused because you say you have the RAK3272S with the RAK3172 Stamp Module:

But you firmware says RAK3172-SiP which would be for the RAK3272-SiP Breakout Board:

Hi Bernd,

Embarrassingly I had installed the incorrect firmware (more than once!) and this was my problem - I hadn’t realized that these were different products. Having now cleared and re-flashed everything’s fine.

Thanks for your help
