nRF Connect App reconnect the BLE fail, when reopen the BLE of the Phone

[ken.oujingxue]

Hi 

I test nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_hrs_freertos on the nRF52840-DK.

and use the nRF connect App to connect to the BLE.

Follow the steps below to test.

1. use nRF connect APP to connect the BLE

2. turn off the BLE of the Phone

3. turn on the BLE of the Phone

4. use nRF connect APP to reconnect the BLE

The BLE connection won't work unless you search for it again.

What causes this? 

But it's ok only on android version 13.

Hi,

Thank you for the videos. Which exact phone are you using? 

As mentioned I have not been able to reproduce this on my end, but I have forwarded it to our app developers so that they can have a look.

Hi, 
For the test video, the phone is Honor 7X.

And I tested two Samsung phones, which automatically re-searched Bluetooth when they turned on Bluetooth, and did not reproduce the issure.

Thanks for the info. From what I understand from our mobile app developer there is not much we can do about it, but at least they are aware of it now.
