nrf connect mobile app searching for BLE device

[Nir Barniv]

Hi Nordic team.

I have a question regarding the nrf connect mobile application.

I am developing a mobile app using react native and ble-plx package for connecting to a device using BLE.

Sometimes, i have issues connecting to the device, our app can't find and connect to the device. I try to kill our app and run it again but it doesn't help.

When it happens, we try to run the nrf connect app instead, and it successfully finds the device and is able to connect.

Are you doing something in the nrf connect app that is different from the usual communication between app and the OS layer?

It seems that the OS stops refreshing the BLE devices list and only by running the nrf connect app the problem is solved.

Is it possible that the nrf connect app bypasses the OS stack of the smartphone? 

Thank you for the help,

Nir.B

Have you tried looking at the Bluetooth "snoop" log?

Hi 

The original case is 2 years old at this point. I would recommend opening a new ticket, and sharing any relevant information you can about what you are trying to do, and the issues that you see. 

Best regards
