Tips and questions relating to the GPS modules from SFE

My GM862-GPS module worked all right in the beginning, but now it does not connect to the GSM network anymore. The GPS part still works. After switching the module on, the Status LED starts flashing fast and after a little while it flashes slow as if connected to the network. I already checked the SIM card in another phone without any problems.

This is the output on the serial port.
Code: Select all

Is there a way to force the module to connect to the network?
