Ok, I've removed the description, still get a 0x2901 descriptor. Definitely have the app subscribed to notifications. What I have noticed is perhaps it's the way the value is being interpreted, if I specify it as an integer in the updateServices with value : cnt
it seems to be coming through as a string representation of the value of cnt.
