Hello Gil,

I am not sure what happened. Maybe a device nearby connects to your HRM device? A phone, or someone else running the ble_app_hrs_c example on another DK nearby. Or if a device (e.g. a phone) connected with your ble_app_hrs, and bonded with it, this bonding information is stored on your device, and it will start advertising with a whitelist. This is basically just a flag that indicates that the DK will only connect to devices in this list. Typically, BLE devices, such as mobile phones will ignore devices with this flag if they know they are not bonded them selves, because it knows it won't be able to connect.

If you press button 4 on your DK while power cycling the device, it should delete the bonding information, and it should advertise without the whitelist flag. You will probably see it from other devices at that point.

Alternatively, you can completely erase the chip, using e.g. "nrfjprog --eraseall" if you have the Nordic Command Line Tools installed, and then program the device again with the softdevice and the example.

Best regards,

Edvin
