Service discovery fails with error code 129 on Android 4.4.2

Philipp Bachmann

Hi

I'm using the Eval Kit PCA 10001 V2.1.0 and Nexus 5 with new Android version 4.4.2. Connecting to the Eval Kit works just fine, but when i perform a service discovery, i get this message:

12-12 10:55:40.980: I/philipba(7356): Attempting to start service discovery:true
12-12 10:55:40.990: W/philipba(7356): onServicesDiscovered received: 129
12-12 10:55:42.550: I/philipba(7356): Disconnected from GATT server.

I also tried your Master Control Panel App and got this error:

Error (0x81): GATT INTERNAL ERROR
Error (0x85): GATT ERROR

The service discovery with Master Control Panel on PC and on Android with OS 4.4 works fine. I tried to restart bluetooth on android, disable wifi or restart my smartphone but nothing helped. Does anybody know this problem and do you have any solutions or workarounds?

Greetings Philipp

    Hi Phillipp,

    Do you have any update on this issue ? Have you tried with other profile ? We sometimes experienced similar issue that the Nexus device couldn't connect to any BLE devices, however a power reset on the tablet/phone would help.

    I am also having the same problem with a Samsung Galaxy S5. Does anyone have any insight into this issue? All the sample programs I compile have the same problem.

    Thanks, Ali

    Hi all

    I got a new Eval Kit and flashed the same stack and the same firmware on both kits. The older kit still had the problem but the new one worked just fine. I don't know what the problem was and i don't have access to the two kits anymore because it was part of a studies project. Maybe there were little differences between the two versions of the nrf51822 chip itself.
