Hi, Sigurd

I don't think my application is calling the disconnect function somewhere, here is the screenshot for it. the highlighted line on No 329, seems like the slave is initiate the LL_TERMINTE_IND, am I right?

Also, it happens with nrf Connect mobile app when I try to connect it with my phone. But this doesn't happen with BeaconSimulator App running on phone.

Regards!

Your application is likely calling bt_conn_disconnect() somewhere. Maybe you can place a breakpoint at these locations, and debug and find out why it's being called.
