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).

Thank you for kind answer.

“closing iOS bluetooth setting window” means kill “setting” app on iphone

[test case #1] step 1. open “setting” on iPhone, select “bluetooth” and click paired(bonded) one(custom service device) in “my devices” (setting => bluetooth => click one in my devices)

step 2. as soon as i kill “setting” after connection with my custom service. my custom service(peripheral device) disconnected. In case of hrs, hids examples, these samples don’t disconnect after kill “setting” in iPhone.

[test case #2.] after connection with custom service device

turn off bluetooth on the phone
after a while, turn on bluetooth on the phone
don’t reconnect automatically with my custom service device but In case of samples(hrs, hids) those reconnect automatically.

[data send & receive] My custom service used "ble_app_template in SDK9” for bond and modified “ble_app_uart” for 128bit UUID custom service. successfully i can send and receive data with central(iPhone) and peripheral(nRF51).

Hi Gabriel,

Please explain what you meant by "closing ios bluetooth setting window" ? You meant you turn off bluetooth on the phone ?

Note that we also have example with 128 bit UUID which is the nRF UART app and also the UART profile in the nRFToolbox. You can test with these examples.
