BLE Pairing

[Gilson]

Hello Gentlemen,

I'm looking for sample code that shows how to enable security which prompts for a PIN number on the Android device when I want to connect to the nRF.

Once this works I also would like to see some source showing how to set a new pin number each time.

I don't want to get into discussions if the PIN method has a flaw. I'm aware of that but right now we would like to start working with PIN method.

So please would be possible for anyone to point me to the sample code?

Thanks much, Gil

The implementation should follow the message sequence chart for GAP Peripheral Bonding: Passkey Entry (Central display) or OOB MSC. Unfortunately I don't think there are any examples for this in the SDK

The opposite of what you want is implemented in ble_app_gls example in the SDK, it implements pairing where the nRF51822/peripheral has a display and shows the pin on a screen. And then, the master/central should type the passkey showed on the peripheral's display. It is implemented according to GAP Peripheral Bonding: Passkey Entry, Peripheral displays message seqence chart.

Hi,

Once this works I also would like to see some source showing how to set a new pin number each time.

The PIN is randomly generated by one of the devices (which one depends on their I/O capabilities) every time pairing is done. On other words, no action needs to be taken to get a new PIN number.

Best regards,
