I’m using the EC25-E / EC200S-EU modules through UART on a custom STM32H7 board with the lwIP stack.
So far the module works great.
If for some reason the module needs to be restarted, on rare occasions, after restart, the module reports no signal (RSSI: 99) indefinitely. Only a repeated restart solves the problem.
SIM is OK, and I’m clearing the forbidden networks list (FPLMN) also.
How should I prevent this?
