ELK-BLEDOM with different char value handle

[Double-A-92]

Hi, I have a LED strip which seems to have a different char value handle and thus isn't supported. Instead of 0x0009 like in the examples, I have 0x000e for the char properties: 0x06.

Those are the commands I could get to work:

sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e00040100000000ef # POWER ON
sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e00040000000000ef # POWER OFF

sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e000503ff000000ef # RED
sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e0005030000ff00ef # BLUE
sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e00050300ff0000ef # GREEN

sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e00010000000000ef # 0% Bightness
sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e00013200000000ef # 50% Bightness
sudo gatttool -b BE:96:50:00:00:23 --char-write-req -a 0x000e -n 7e00016400000000ef # 100% Bightness

And here the full gatttool output in case it's also needed:

Ok, i think it is posible use it with little change developed.

Please i need the blietooth name of your led strip.

You can know the name with BTScan.py:

You can scan BT device with BTScan.py in my repository exec: sudo python3 BTScan.py, code supports led strips whose name begins with "ELK-BLE" or "MELK" or "ELK-BULB"

It's ELK-BLEDOM which should already be supported.

But actually it might be a general error with my system and bluetooth... Sorry about that.

My code use uuid - 0000fff3-0000-1000-8000-00805f9b34fb not char value, i review code but i think it is for different reason. Please use integration and get debug logs and post its. I explain how to in other issues

You need bluetooth integration in https://www.home-assistant.io/integrations/bluetooth

If you haven't it, you need install it
