Do I have to setup the AT!MAPUART=1 from USB? Or is this command also possible via UART?
My problem is:
The Module is used on a pcb, where i have only connection to UART.
The main communication seems ok, because i get answers from the Modem. But CMEE=1 doesn`t change the error reporting.
AT+CPIN? answers with +CPIN: SIM PINOK but if I try to send pin with AT+CPIN=1234 I only get ERROR.
For me it looks like I can only use a small part of the AT commands. I tried to map the UART to expand the AT commands with
AT!ENTERCND=“A710” and after that AT!MAPUART=1. Answer is OK but nothing changes…
Also some commands just return OK instead of information. e.g. AT+CGSN? returns just ok instead of IMEI
Can anyone help me?
