What are you trying to do here exactly, what is your use case?

BLE devices are not like Bluetooth Classic devices. In most cases you need a dedicated mobile app to connect and interface with the BLE device unless it supports some standardized Bluetooth SIG service like HID (for a mouse or keyboard for example).

In any case it sounds like your question is more of a generic Android/iOS question which you need to ask on forums related to those platforms.

Hello @tmonte

Thank You for your response !

Use-Case :-

1.) Pair and connect to ble device without any App Interaction. (Mobile Settings)

2.) Once paired, the device should auto-connect next time, in situation's occurred mentioned below

     a.) power cycle of ble device

     b.) Remote device (mobile) Bluetooth was turned off and turned on

3.) Once the ble device is connected mobile should show notification to user about device connectivity.

4.) Please suggest if any specific profile to be used for mobile to show notification about ble device connectivity, without any mobile app.

Please share any link or tutorial to achieve above use-case.

Thank You ! 

Well you are just providing a requirement about connection from a mobile device. From the EFR side the only side you need to do is to advertise when not connected.

The mobile piece you need to investigate on mobile related forums, we don't provide support for mobile app development.

Hi tmonte,

1.) How to avoid deletion of bonded device from EFR device after power cycle ? (We are using Thunderboard EFR32BG22)
