Hi there @yungipark,

Would you mind providing a little more information about this error if you could? Are you seeing this error using a new IC880a gateway module?

Thank you very much!

Hi, I’m using Gateway module RHF0M301-915, PRI 2 Bridge RHT4T002 with Raspberry Pi 3 Model B.(refer to this wiki)

I also faced the same problem on the balena log with the following message:

I followed the configuration guides in jpmeijers/ ttn-resin-gateway-rpi on reset_pin_values. Owing to I’m using gateway module RHF0M301-915, I assumed is fall under Rising HF Board with pin reset value, 26.

I also slightly increase the power supply for the gateway as usually I connect the power supply USB to my laptop’s USB port (~0.5A). I had increase the power supply to 1A to test whether is the insufficient power supply causing the error. But the error remain.

Hope can get some insight from the forum. Thank you.

I follow the guidelines (RPi+RAK831+Resin image => failed to start the concentrator)
I have set the SPI_SPEED to 8000000 in the device environment variable and reboot the device.
I also try to add the following line in run.py in the terminal on the summary of balena Cloud device:
if ‘lbt_cfg’ in sx1301_conf:
print “Removing LBT configuration”
del sx1301_conf[‘lbt_cfg’]

and the problem solved.

Thanks for letting us know !
I took the liberty of marking your last post as a solution to the problem, as it contains the link that helped you - let me know if that’s not what you wanted. Thanks !
