BG770A-GL vs BG96-B Cellular network AT command response times

IoT Modules LPWA Module

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

BG770 modules are support these commands.If the other commands work properly,ensure that the command format is correct please.

Hi @AMediumRamen
Also, please check current BG770A-GL module fw version, probably you need to update to latest one.
