Join Request approved by gateway but not received by device

helixembedded · ‎2025-01-29

Hi,

We are developing a LoRa application using the STM32WLE5JC chip. The product is to be implemented for multiple deployment regions (EU, US, AU and AS). We have a problem with the US configuration. When a device sends a join request, the first attempt always fails, but then the second attempt succeeds. The strange thing is that we can see the gateway accepted the joinb request, but the device still says join failed.

See screenshot below:

The highlighted area happens to conincide with when the gateway accepted the join request, but the device still claims the request failed.

Note: HYBRID_MODE was originally turned off, and requests always failed. When turned off, then we experience the above.

Any thoughts as to potential sources of this issue?

Thanks.

Hello @helixembedded

Can you see any transmission/reception on the gateway side. I think the trace messages are not correct. Could you try using a code already tested on a working board.

Best Regards.
