Ble rare disconnection on softdevice with active timeslot session.

[Valer_I]

Hi, During testing I noticed rare BLE connection loses with Softdevice S110 when timeslot session is active. It is hard to catch them with sniffer due to rare behaviour. So the question is about ever known reasons of connection loses while timeslot session is enabled. Note: No reboot/hardfault occured because I use watchdog for 30s and seen logs on central side, it restores connection emmediately.
Thanks.

UPDATE: SD_LINK_STABILITY.pcapng

I use distinct sound notification on device at connection, disconnection and firmware start. So thats why I can exclude hardfault or reboot.I do not use sdk, but only "sd_ble_" level API. I do not caught reason yet because I can get it on peripheral side only, and device is not connected to debug interface. I think of passing this data to central over ble after reconnection. It occurs 2-3 times a day, sometimes at night.
