Hi Dan

I think RK and others have discussed this extensively on this thread.

Couple of options you have. If you are on S110 V8.0 you can change the memory available for GATT characteristics which might help, and there is a flag somewhere which lets you keep the characteristics in user memory instead of using the softdevice stack memory.

That indeed seems to be the case. I am getting an error 4 (NO_MEM), but actually later, when I am initializing the Nordic UART service (which I'm using for debugging). A little disconcerting, as I didn't realize I was operating so close to the limit ... Thanks for the response.

Are you checking the return value from the call to add the description? I wonder if you're running out of memory.
