Hello!
Using SX1302 + ublox neo-6m gps module. PPS is connected correctly.

After some time i get this error and class b device communication stops working:

Tue Jun 25 18:57:13 2024 user.info chirpstack-concentratord-sx1302[8201]: Enqueueing packet on pps, downlink_id: 412675477, counter_us: 3811104986, current_counter_us: 3940987438
Tue Jun 25 18:57:13 2024 user.warn chirpstack-concentratord-sx1302[8201]: Enqueue beacon failed, error: TooEarly

May someone can help me to troubleshoot this issue?

Any clues anyone?

Which mode is more stable gpsd or directly via /dev/tty* (handled by semtec hal)?

Or is nobody using class B and chripstack has no great class B support?
Are there any lora stacks for sx1303 which have better class B support?
