BLE advertisement stops after connection

Hi All,

Fixed it.

(I'm writing this from bed after I realized the fix(mistake) in my sleep)

Mistake was use of bt_conn_ref in the connected callback on line 87. The application is taking the connection reference and not dereferencing it which is required in this case as the function increments the counter. As soon as the counter is incremented to 2, there's no need to advertise and hence we get the error on data update.

Thanks Sigurd for looking into the issue.

Also note that this is happening not when all 2 or 3 connections are made at the same time, rather when connecting for the second time after disconnection. Number of connections remains max 1 at all times.

No errors being observed in start or stop of advert. Also tried checking if bt peripheral is working using bt_is_ready() which returned true every time.

Hi!

Are you getting any error codes returned from bt_le_adv_start() when this happens?
