From my other thread, about the WMANTSEL command, i found out that apparently the command AT+WMANTSEL=1 is related to my registration problem. As a test, i left my system without the AT+WMANTSEL=1 command in the initialization of the modem, and until now it is registering and communicating with no problems. I want to try and reproduce this repeatedely now.
Sorry, i cannot work with the FW.exe, this is a remote system (that’s why i am kind of slow to run the tests).
