Hello,
I’ve been using the BG96 module for a while and have not have any trouble with the following AT command sequence to connect to and ensure connection to a network operator(without going into too much detail).
AT
AT+CFUN=1
AT+CGDCONT=1,“IPV4V6”,“APN_NAME”
AT+COPS=0
AT+CEREG?
AT+CGATT=1
AT+CGATT?
AT+QIACT=1
AT+QIACT?
AT+QNTP=1,“time.google.com”,123
AT+COPS?
However, with the BG770 module, some of these commands simply do not respond or have the response “ERROR”. Mainly:
AT+COPS=0 <====== No response (times out at 30 seconds BG96 usually takes around a second for response, looking for an OK response)
AT+QNTP=1 <====== times out at (times out at 30 seconds BG96 usually takes around 3 seconds)
Are there any commands that the BG770 needs on top of the commands listed above to ensure smooth connection procedure?
Thank you for your time
