How Master device pair with android app with secured key.

Hi Nordic,

Our device as master need to pair with android APP. We want to add function that pair with secure key. when APP pairing with our device. Our device will display secure key and APP pair with it by inputing displying secure key. how to implement it. do you give some info about it. The best is example or demo ,even through application note. Thanks.

  • So the nRF52 is a central/master and the Android device is a peripheral/slave.

    Then you can follow this MSC to implement pairing with passkey entry.

    You can have a look at the Glucose Application example for how to implement this, but we don't have an example for a central application.

  • Hi Petter, Thank you very much. Now Our device pairing with app with secure key that is ok. but we meet another problem for OTA after adding it. We update our device firmware with nRF Toolbox DFU app by OTA. But the nRF Toolbox DFU app seem not to support pairing our device with secure key . it not connect our device all the time. Before Our device without secure key. so OTA is ok. how to OTA device pairing with secure key ? do you have new tool or newer version's nRF Toolbox DFU app to support it? On my side, the nRF Toolbox app version is V1.16.5. Thanks.
