Hi George,
so LG290P board should run with 3.3V together with an
ESP32 on the UART interface continuously without any problems? But it does not, because LG290P board stopped working after a view hours running well sending data to ESP32 UART interface. Now only blue Vcc LED is on and red LED flashing when GPS data received, can not be recognized any more. Stopped also sending data to QGNSS by USB interface, when connected by USB cable to the computer.
Also does not accept any commands sent by QGNSS to the board. All worked well before. What can I do to make the LG290P board running again?
