Most likely, GPIO_CHIP and RESET_GPIO are defined incorrectly.
Is there a known pin configuration for this hardware?

Hello @0xFACE

Unfortunately I don't have that device to test but doing some research I found this information for the same board (bobcat-rk3566, G290/G295, 2 GB): https://github.com/NebraLtd/hm-pyhelper/blob/35f1ba2d5c08e859988b1d6e5bb8bc33b986dffa/hm_pyhelper/hardware_definitions.py#L708-L727

This would mean the bus is /dev/spidev5.0 and the RESET_GPIO=149. Translating that into GPIOd it would be gpiochip4 port 21 (149 = 4*32+21). Note that this is all untested based on information online so I'm not 100% sure but worth testing.

Edit: formatting.

Hello @xoseperez

Thanks for the response. This would match the data from this repo: https://github.com/sicXnull/Bobcat300-DebianMinimalDocker/blob/main/packet_forwarder/tools/reset_lgw.sh.bobcat

I'll try to test it and share the results.

Sorry for the delay. I bricked my Bobcat after a kernel update, so it took me some time to reflash the system ;-)
Currently, the basestation is running correctly with the configuration provided below:

However, there is one strange behavior that I cannot explain. After several hours of operation, a red LED lights up on the LoRa module. Everything continues to work properly, but I have no idea what this red LED means or why it turns on. I do not have any documentation or information regarding the manufacturer and model of this mPCIe module:
