Sometimes some BLE frames have been received with parasite value.

For example, when computing muscles values form sensor inputs, some "pic" values are received like 90 (when a slider in high position) or 2088 (even if values should be in [0 ; 1024]

When clicking on the box buttons, display the version of the software which is embedded in.

It seems Baah box broadcasts Bluetooth Low Energy frames with some noise.
Indeed while using a slider plugged to the box, with no actions made on this slider, the box sends frames with non-null sensor data.
These fake frames parasite the app which thus receives inputs made by... noone.

See below a sample of a BLE frame received by the app from the Baah box where nothing has been done on the slider. In this case there are inputs on the two muscles channels.

BLE frame: C1 | a1 | C2 | a2 | JBin | 90
BLE frame: 28 | 0 | 90 | 0 | 1 | 90
