nRF5340 - peripheral disconnection because out of range

[Gabriele]

Hi,
I'm working on nRF5340 Bluetooth LE peripheral (building environment: NCS 2.6.1, Zephyr 3.5.99).
The net core is populated with the Zephyr HCI RPMsg sample LE Controller as it is.
I experience a disconnection from peer with reason BT_HCI_ERR_CONN_TIMEOUT.
This occurs because the peer is moved out of range.

How to get the application notified in advance of this disconnection event ?

Hi Gabriele

Okay I see. I think it would be easier for you to follow my colleague Susheel's advice in this ticket, as you will have a lower downtime if you do one of the suggestions there:

a) Change CONFIG_BT_MAX_CONN to 2 and allow an overlap of roles

b) Create a worker thread to start the advertising as the disconnect callback has exited.

Best regards,

Simon
