ble_app_uart device is not supported

[Ron]

Hello,

I'm just getting started with my nRF52832 and I am still trying to get the first example of the tutorial page running (Getting started with nRF5 DK. I did everything as described. I work with the SDK V11, Keil 5.21, Termite. Everything works fine, until it comes to using the nRF Toolbox app. I have an HTC One M7 which has Bluetooth 4.0 (HTC One M7) and Android version 5.0.2. But, when I try to connect with the app, it says connected for a fraction of a second and then uncennects and says device is not supported. The log shows the following...

Does this mean my phone is not ready for BLE? I thought that BLE = Bluetooth 4.0.

Thanks for your help.

I cleared the bonding and now I get a different error. After connecting and discovering the services successfully, it is stuck in gatt.writeDescriptor(...) and shows error (0x85): GATT error after a few seconds. It disconnects afterwards and shows error(0x8): GATT conn timeout.

I retried more often and once I got it perfectly running, but couldnt repeat this afterwards and dont know what I could have done differently that time.
