Hi there,
There are 2 different interesting points in your trace.
The first one, at 12:51:52 (handle 0x000A) is simply the result of the Master Control Panel trying to read an attribute that is not readable. This not in itself an error, some attributes do not have read permissions, depending on your application this makes sense, I think you can safely disregard that one.
The second one at 12:52:03 is an ATT timeout. The Master Control Panel tried to read an attribute but received no response from the nRF51. This, as Ulrich mentions, is usually because the application has not supplied the system attributes to the stack, and it is very easy to fix. If you are using the SDK and the bond manager, those should take care of this for you.
If you are not, then you simply need to handle the event as Ulrich describes, and you should be all set.
