STM32WLE5 Module JOIN FAILED

[ethan2]

Hi,

I'm doing tests based on the LoRaWAN_AT_Slave. One of the modules often appears tMAC txTimeOut, resulting in JOIN FAILED. Same firmware downloaded, but some devices are working, is there any doubt? Is it a hardware problem?

Hello @ethan2 

Could you please provide more details. What is the exact module you are using (a third party module or a module based on your own design), what is the code you are using and all your use case details if possible.

Best Reagards.
