Note:
–
The analog port is limited to 5V maximum.
–
Use only cable/metal contact designed for Molex MicroFit connector.
–
The application will NOT check the command <cmd> entered. It will execute the command even if the command
is invalid.
–
When triggered, the command will not output any response to the external serial port.
–
Do not enter "interactive" command (i.e
+CMGS
,
+WDWL
,...), otherwise the application will be stuck waiting for
user input.
–
If +ADCAT is enable, no other AT command can control the analog port.
