Switch to AT command mode
In transparent transmission mode, you can temporarily enter AT command mode by sending
a command sequence. At this time, if a valid command isn’t received within timeout
period(default 10s), module will automatically return to transparent transmission mode; if the
module needs to quickly return to transparent transmission mode, you can send AT + EXIT
command.
If module want to stay in AT command mode,send AT + ATMODE = 0 to activate it. If the
module needs to be in AT command mode after restart or reset, execute AT + SAVE to
save parameters. See the following example:
+++
OK
AT+ATMODE=0
OK
AT+SAVE
OK

through the channel mask command (usually 8 channels are a group), such as selecting
