I implemented the dynamics management system using by HL7539.
I would like to know the alternative command of
AT+CIND. I want to know the following infomations:
- Whether is the module out of service or not.
- Whether is the module connecting to the mobile network or not.
We used the 3G USB dongle which can use the “AT+CIND”. This command is providing necessary informations. However, Sierra HL7539 doesn’t have “AT+CIND” command.
