[OPQ]

Hi ,

nRF52832 using pairing connection with Android phone,after repeatedly disconnect and re-connect ,after several minutes will maybe make the phone's bondibng information deleted.

Could you please help to tell what maybe cause this?

I try the that the encryption_failure() function will delete the phone side's bonding data,but not sure.

Hello,

Some phones may delete bonds after many unsuccessful connection attempts. Could you please explain this statement ''BLE device sends the encryption_failture() function to the phone''?

What is in the code and what do you see on the phone?

Can you send the sniffer traces to us?

It is helpful to know about phone model and operating system version you are using.
