Bluetooth Protocol

The Calimotion Mobile App uses a Bluetooth 4.1 BLE pairing communication protocol. The Calimotion will have its button LED turn blue when a Bluetooth communication is established with a mobile device. The main usage of the Mobile App is to communicate with the Calimotion using the following public BLE service and characteristic:


This is the primary service to establish a pairing Bluetooth communication with the Calimotion:

UUID: 00000100-5122-4338-a5cc-fda9f670bbe0

LED and Sound Characteristic

This is the main characteristic available from the BLE public service of the Calimotion. This characteristic contains a 20 bytes data frame to activate LEDs and set the volume.

UUID: 00000106-5122-4338-a5cc-fda9f670bbe0

Properties: READ, WRITE

Ex: 0x01:00:FF:FF:FF:FF (Set LED into RGB mode to full, with maximum volume)

The characteristic data value is the following:

Byte [0]: 0x00 = LUX option, 0x01: RGB option.
Byte [1]: If LUX option (0x01) is selected in byte 0, set the LUX ID to use.
Byte [2]: RED, if RGB option (0x00) is set in byte [0].
Byte [3]: GREEN, if RGB option (0x00) is set in byte [0].
Byte [4]: BLUE, if RGB option (0x00) is set in byte [0].
Byte [5]: Volume, 0x00 = OFF, 0xFF = Max


It's also possible to connect directly with the Calimotion using the nRFConnect app.

Here is a example to connect to the Calimotion with nRFConnect Mobile app.
