Noted and understood.

Thanks for your support.

No problem. Onto the new question, we try to keep one DevZone thread focused on one topic only. Therefore, when the topic changes, please try to start a new question. I will note down some short answer still.

Yes, it is possible.

If your device supports more than one connection, then you can also maintain a connectable advertisement as long as you have not reached the maximum number of connections.

If your device has reached the maximum number of connections, it can still maintain one or more non-connectable advertisement.

For further details, there should be some existing DevZone questions on this question, that you can look up with the search feature or an internet search engine.
If not, please open a new question.

Thanks. I wonder if it is possible to keep advertising while one connection is active, with nrf52832?

Yes, that's what I mean.

I don't think you should comment out bt_conn_unref().

Keeping your own flag is one approach. It works fine if you only support one connection.

If you plan to have multiple connection, you can upgrade to using your own struct that has the bt_conn structure as a field and a flag.

I think I understand what you mean.

in on_conncted() Icall

my_conn = bt_conn_ref(conn);

but in on_disconnected() I

call bt_conn_unref(my_conn);

So I assume this makes my_con invalid?

Should I keep my own bool flag for connected and set/reset in the callbacks, or might I just comment out bt_conn_unref() ?

Thanks

Hi Johanan,

How are you setting up your my_conn pointer? I wonder if that structure is still valid after a disconnection.

BR,

Hieu
