disconnection problem after closing ios bluetooth setting

[gabriel.lee]

hi, I am using the nRF51 with code from SDK 9, as well as the S110 softdevice and made a custom service(128-UUID) with bond using device manager.

connection and service procedure is ok but there is some problem.

In case of sample (hrs, hids) projects, these projects keep connection after closing ios bluetooth setting window and can reconnect with peripheral(nRF51) when peripheral device restarts.

But in my custom service project case, it cannot keep connection after closing ios bluetooth setting window and cannot reconnect with peripheral device when it restarts(turn off and turn on).

please kindly advice me

Hi Gabriel,

If your device is not a HID device, you should not use the Bluetooth setting to connect/bond to the device.

You should use your app to connect.

This explains why the operating system disconnect when you close the bluetooth setting (because there is no app require the connection then the OS will disconnect that connection).
