I am using QUECTEL M95 modem to connect the server using gprs . And the modem has facility to send and receive test messages .In my project both the situation occurs . By default in programming ip address been set, but there are chances for updating the ip address by sms . Wheather it is possible to send sms during gprs mode? If possible how ? Please suggest me how to do.
Yes, you can do it. If you are using Transparent mode (AT+QIMODE=1) you need to switch to Normal mode (AT+QIMODE=0) and you can send SMS using AT+CMGS regardless of active gprs connection.
