Hi all, i had a wavecom module q2501b working for soveral days, connnected to a server and transmiting its position(gps). One day, i simply had no responce from the module. When i connected a serial cable to it, there was no reply to AT commands(no echo either). After disconnecting the module and connecting it again, my firmware started to run ok. IÂ´m afraid it will happen again, it looked like the OpenAt firmware wasn’t working. Did anyone experience the same problem? is there any way of fixing it without using an external watch-dog circuit?
