Modem GSM M100 3G : problème d'initialisation du modem 🔒

In some case an initialisation problem of the M1003G modem can arrive.

You have this problem when Alert is sending an AT command and the modem doesn't answer yet but answer OK to the next AT command and OK again to the AT+CPIN command.

Sample :

S: AT<CR>

R:<CR><LF>OK<CR><LF>

S: AT+CPIN?<CR>

R:<CR><LF>OK<CR><LF>

This problem is solved in version 3.6 rev 2 build 20 and in version 4.0 rev 2 build 273

In version 3.6, you need to add the following lines in the Alert.ini file (Alert should be stopped first)

[ComOpt]

CFUNCommand=AT+CFUN=1<CR><LF>

MaxFailBeforeHardReset=3

In version 4.0 these variables are configurable from the system's options système. you have 2 variables ComOpt.CFUNCommand and ComOpt.MaxFailBeforeHardReset.
