6LoWPAN sub GHz mode: example client fails to register to Connector #93

Closed kimlep01 closed 6 years ago

After starting the border router in 6LoWPAN sub GHz mode I see the following error constantly:

The example client is able to connect to the 6LoWPAN network (very slowly) but fails to register to Connector. In 2.4GHz mode I didn't see any issues. Updating Atmel driver to latest master version didn't help.

Boards used as border routers: F429ZI / K66F

Border router configuration:

"rf-channel": 1, "rf-channel-page": 2, "rf-channel-mask": "(1<<1)",

mbed compile -m NUCLEO_F429ZI -t IAR --app-config ./configs/6lowpan_Atmel_RF.json -c

@kjbracey-arm Can you help?

What can cause this radio issue?

SeppoTakalo commented 6 years ago

Did one end of the communication happen to be ST based device? Is this the same issue we have seen earlier https://github.com/ARMmbed/atmel-rf-driver/issues/53

kimlep01 commented 6 years ago

Tested with the following combinations: F429ZI border router - K64F node K66F border router - K64F node

This solved the issue -> https://github.com/ARMmbed/atmel-rf-driver/pull/66

@karsev what kind of tests were performed on the system to assess that the issue is solved?

On our side Tridonic we still see the issue, or at least some issue related to the radio, also with this fix. We are struggling to get a setup were we can get the issue to pop-up in a reproducible way, and thus are also unable to assess in a proper way whether it has been really solved.

Thank you a lot.
