1.2. Description of Data Mode
The COM port of BG96 module has two working modes: AT command mode and data mode. In AT
command mode, the inputted data via COM port will be treated as AT command. While in data mode, it
will be treated as data.
Inputting “+++” or pulling up DTR (AT&D1 should be set first) can make the COM port exit from data mode.
To prevent the “+++” from being misinterpreted as data, the following sequence should be followed:
1) Do not input any character within 1s or longer before inputting “+++”.
2) Input “+++” within 1s, and no other characters can be inputted during the time.
3) Do not input any character within 1s after “+++” has been inputted.
When AT+QFUPL, AT+QFDWL, AT+QFREAD and AT+QFWRITE are executed, the COM port will enter
data mode. If customers are using “+++” or DTR to make the port exit from data mode, the executing
procedure of these commands will be interrupted before the response is returned. In such case, the COM
port cannot reenter data mode by executing ATO command.
