Hi , I am to trying to send and receive sms in EC200u module. In Quectel EC200u eval kit ,the sms function is working fine.
We are using our own gsm board interfaced with external MCU, here I am not receiving the notification RING ,+ CMTI for both CALL and SMS operation .
I have checked with the following commands both individually and together :
AT+QINDCFG=“smsincoming” ,1,0
AT+QINDCFG="ring" ,1,0
AT+CMGF=1
AT+CSCS=“GSM”
AT+CSDH=1
AT+CNMI=1,2,0,0,0
AT+CPMS=“ME”,“ME”,“ME”
Kindly help me with a solution
