Hello,
I’m using a RAK2287 with a RPi4 along with BasicStation to create a gateway device to deliver sensor data through to AWS IoTCore with CUPS authentication.
After starting my gateway it seems as if things are going well, but after a few minutes I get a number of ‘time sync rejected’ messages and sometimes some Repeated excessive clock drifts between MCU/SX130X#0
messages before the station disconnects and restarts.
What does this mean, and what could cause it? Logs below.
