Hello all, i work with a system that uses the HL76xx modem series, and currently we want to support the HL7692, HL7618RD and HL7688.
The main development was made on the HL7692, and when I was “porting” it to the HL7618 (Verizon) I have some strange behavior: I cannot save the user profile. For example, i set AT+WMANTSEL=1 and then AT&W. After a module reset with AT+CFUN=1,1 the setting is lost, returning +WMANTSEL: 0 again.
I can observe some strange things like this also with other commands, like AT+CGREG=1 that is lost after a power cycle and sometimes with AT+KSLEEP=2.
In the HL7692 version i don’t see this.
Any idea why this might happen?
