Hi,
I used sdk11 and sd130 at a 51822 project, it is required to be paired with a key for both andriod and ios, everything is fine but the dfu on andriod, I used nrfconnect to test dfu, for IOS it is always ok, but andriod always failed after it is paired, and always ok if it set to not paired, the error code on nrfconnect is always GATT INVALID HANDLE.
