AT
in the serial monitor and pressing
[Enter]
. The uploaded program passes on the
command to the ESP module, which in turn answers AT and then OK. The next
command that you can test is:
AT+GMR
This command outputs the current firmware and version number.
The command
AT+RST
resets the module. You will see a few illegible characters on the terminal first,
followed by ready, which says that the module is now ready. Another command is:
ATE0
This permits deactivating the echo of the module. This means that the command
you sent will not be returned, but only the answer will be. For example, if you send
AT, the response will not be AT and then OK, but only OK. However, for your first
attempts, it is recommended to reactivate the echo with
ATE1
.
