I verified your patch to select the proper notify characteristic, and 
that works correctly. I suppose that this patch does not break other 
already working BLE devices, so this one should go in master I think.

Yes, did that, and then the receiving/reading of data is still no yet 
working (not surprising as I had the correct notify characteristic hard 
coded selected). I found out that BLEObject::characteristcStateChanged() 
is never called in my situation, so no incoming packets are seen. Not 
sure why (yet).
