Bluetooth BLE device not get discount

Vikrant More <vikrant8051@...>


Currently I am working on Zephyr Bluetooth APIs to build  normal Services-Characteristics based BLE device.

I've observed following things:
1) sometimes when app (for eg. nRF Connect) closes even after that device doesn't get disconnected

2) sometimes even smartphone Bluetooth switched off then also device doesn't go from connect state to disconnect state.

Success ratio is approx. 60-70%

Since device doesn't go in disconnected mode, it stop advertising & I have to restart it for reconnection.

Is it because of App or smartphone OS not actually disconnecting at background level ?

Thank You !!
