Hi All,
I have a Domyos EL 2818 that uses the Bluetooth Low Energy (BLE).
With the last software update, the Android App does not work well, It often disconnects and sometimes, when connected, the console screen of the Domyos EL 2818 goes off.
I haven't used BLE before, but I found the Erel's BLE Library here and I tried to connect with it.
It works very well (I didn't have the slightest doubt) so I can read the services and characteristics.
I noticed that when connected, the console screen goes always off, but I'm able to continue reading data from the Domyos EL 2818 without problems.
The datas are always the same:

Service: 0000180a-0000-1000-8000-00805f9b34fb
Char: 00002a29-0000-1000-8000-00805f9b34fb Stringvalue: ISSC Hexvalue: 49535343
Char: 00002a24-0000-1000-8000-00805f9b34fb Stringvalue: BM70 Hexvalue: 424D3730
Char: 00002a25-0000-1000-8000-00805f9b34fb Stringvalue: 0000 Hexvalue: 30303030
Char: 00002a27-0000-1000-8000-00805f9b34fb Stringvalue: 5505 102_BLDK3 Hexvalue: 35353035203130325F424C444B33
Char: 00002a26-0000-1000-8000-00805f9b34fb Stringvalue: 009500 Hexvalue: 303039353030
Char: 00002a28-0000-1000-8000-00805f9b34fb Stringvalue: 0000 Hexvalue: 30303030
Char: 00002a23-0000-1000-8000-00805f9b34fb Stringvalue: Hexvalue: 0000000000000000
Char: 00002a2a-0000-1000-8000-00805f9b34fb Stringvalue: Hexvalue: 0000000001000000

That are some informations about the console as chipset (I think), software version and so on...
Probably, after connection, I have to send some command to ask for other values as speed, time elapsed, heart rate etc... I presume writing some bytes to a characteristic.
Is there someone that experienced with this device or something similar that can put me on the right path?
Thanks!!
