NRF52840 dongle running blinky connects with nRF connect app but wont pair to native Android Bluetooth utility

[apdobaj]

I'm running the unmodified blinky example on the 52840 dongle PCA10059 and it connects just fine with the nrf connect app but will not pair with the phone via the Android native "Pair new device" dialog. It's advertising but clicking on the "Nordic_Blinky" advertisement does nothing.  I have a custom app that I'm trying to connect to the dongle and it doesn't connect either. What am I missing here?

Hi,

The reason it won't pair is because the native android bluetooth utility allows for pairing so the phone sends a pairing request. The blinky examples does not support pairing/bonding at all so when you try to connect it will fail. Our nRF Connect when pressing "Connect" just sends a Connection Indication, which is why you are able to connect. However, you may click 3 dots on the "Connect" button and select "Bond" which is the same as the native android bluetooth utility.

OK thanks for that explanation. Why does the blinky example not support pairing/bonding and how do I change it so that it does? I'm running custom firmware on the dongle and use blinky as the baseline, if the intent is to connect with a smartphone should I be using a different example as my baseline? Thanks for the info!
