BLE connection problem

DragonAnger

Hi,

I'm using sdk12.3.0 ble_app_uart.

My problem is BLE connection.

Sometimes(almost 50%)I tried to connect BLE but fail and I have to connect again.

I don't know why.

This image is messages that I captured when connection failed.

What is the problem?

Thank you for reading my question!

    Hi,

    A quote from this thread on a similar issue (Device is not supported message).

    I suspect the android device is still not making full device discovery for the services and still has an old gatt table with services that you previously bonded with. Try to go into Bluetooth settings on your phone, forget all bluetooth services/devices that you have listed there and perhaps disable Bluetooth and enable it again. Then try to connect with the nRF52 device.
