Android app

[Sebastien]

Hi, i'm currently using two NRF52 (1 central and 1 peripheral) using the ble_app_blinky and the ble_app_multilink_central.

I would now like to connect my Android phone with the Central in ordrer to control several NRF devices.

How can I do ? Thank you !

Hi,

If you have a phone with a recent Android version, you can setup nRF connect to do advertising to allow the central to connect to the phone. This is supported from Android API version 21.

A more common approach is to setup the central device to also be a peripheral. You can find an example of concurrent central and peripheral in these SDK examples. This will also allow phones that don't support advertising to be able to control the peripheral devices.

Best regards,

Jørgen

Ok, if I use the BluetoothLeAdvertiser method how to tell the Central the ID of my phone ?

Thank you very much

The central will receive advertising packets from the phone. You should fill the advertising packets with data so that the central can identify the device. For instance, the multi-link central will connect to any devices which advertise the name "Nordic_Blinky", while the BLE UART client example will connect to devices advertising the NUS UUID.
