Hello,
I'm using nRF9151 as a HCI host and nRF52840 as HCI controller (nRF52840 config is based on HCI lpuart example). Recently I updated NCS to 3.2.2 and I started observing the lack of disconnect event on a supervision timeout. The issue didn't occur when both (nRF9151 and nRF52840) apps were on NCS 3.1.0 but also it didn't occur when nRF9151 app was already using NCS 3.2.2 but the nRF52840 was still on NCS 3.1.0.
I found out that it was a known issue, which was fixed on NCS 2.8.0.
Are you aware of that issue on NCS 3.2.2? Maybe it is already fixed on newer NCS versions?
Regards
Filip
