Serial Output

ESPGeiger has a software Serial interface allowing simple UART communication.

The default baud is 115200

Each command should be terminated with \r\n

Note that Serial commands are disabled on ESPGeiger-Log builds. This is due to the Serial RX pin being in use for the user input button.
