Smartphones will connect automatically to devices that has a service that is natively supported by the OS. typically HID for Android and iOS, and also ANCS for iOS. An alternative would be to have a background mode in your application where the application will scan for your device even if it is not in the foreground.

Hi,

There is some mistakes in my expression as a foreign people using English to.describe questions.

In the example "ble_app_hids_keyboard" based nRF5_SDK_15.2.0_9412b96, I found my smartphone can automatically connect nRF52832 after bonded without needing someone to do connecting operation.

I also hope my project owing the same feature that everytime my smartphone can connect the nRF52832 automatically without needing me to do connecting operation after bonded. But I do not know how to modify the code in order to realize this function.

The main use of nRF52832 for my project is to transmit data. So I modify the code of example "ble_app_uart" based nRF5_SDK_15.2.0_9412b96 to realize all the features which my project need.

Finally, I wish you can give me some guidance to help me achieve the feature.

Thanks very much for your help.

Best regards.

Tianfei

Hi,

If you are making a central that should reconnect to a known device automatically, you should start scanning again and check the scan reports against the known device list. I would recommend that you take a look at our tutorials section here for more details on how to make a central device.
