No need to be sorry.

Good to hear that you were able to find a device which had the expected behaviour together with the nRF52832.

Do you still need support with this ticket? If not, I will close it.

Best regards,

[quote user="ovmori"]I see the problem for bonding.[/quote]

It could be that one of the devices deletes the bonding information while the other one doesn't. If the Android device deletes the bonding information, you can configure the nRF52832 to delete the bonding information as well. The new bonding request will be the same as the initial one in that case.

Is the data sent after the devices should have been bonded and paired? Note that some phones may use "pairing" instead of "bonding" as terminology.

Can you do a sniffer trace which includes the first successful bonding, disconnection and failed bonding?

I am not familiar with OPPO and if they modify Android to fit their devices better. Do you have any information on this?

Thank you for your reply.

I will answer as following

Where do you see the problem: for pairing without bonding or for bonding?

I see the problem for bonding.

How is pairing/bonding canceled?

When data is sent from Android (central) to nRF (peripheral), a pop-up with "Bluetooth pairing request" appears on the Android. So I determined that the pairing/bonding was cancelled.

I'm wondering if it might happen after being disconnected due to a timeout and then reconnecting after a long period of time, or after that disconnection and connection happening frequently. I don't know the details of the sequence yet.

Which device cancels pairing/bonding?

At the moment, I don't know if it's canceled by Android or by nRF.

Have you tested several Android devices? If yes; do you see the problem for all of them?

I tested it on several OPPO smartphones (Android v11 and v12) and had the same issue.
