WiFi provisioning
^^^^^^^^^^^^^^^^^

The device needs WiFi to be able to communicate with a remote server. To provision WiFi credentials, follow these instructions:

- Connect device power (12-24V at V+ and V-, or USB).
- After a few seconds, the device should start blinking a Data LED with a purple color.
- At this point, the device acts as a Wi-Fi Access Point and emits a Wi-Fi signal with its serial number.
- Using a mobile phone or any device capable of running a web browser and WiFi, connect to the device WiFi network (e.g., MM2R02IM0001).
- Password is not required, but on an Android device, click "Yes" to allow the device to connect to the network without internet.
- Open any web browser and go to the address: ``mm.local``.
- An input form should be available.
- Enter Wi-Fi SSID and password and click "Submit".
- The device should restart in 4 seconds and attempt to connect to the provided network.
    - If the network LED starts blinking green, it means that WiFi is available and the device is connected.
    - If the network LED starts blinking red, it means that something is wrong.

Factory reset
^^^^^^^^^^^^^

In case the WiFi credentials are wrong, or the Wi-Fi Access Point (AP) has changed, perform a factory reset. To perform a factory reset:

- Remove the plastic cap.
- Plug in the device to power.
- Press and hold the reset button until the device blinks twice on the network LED, once on the data LED.
- The device should start blinking purple.
