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

It seems strange that the connection is lost without any warnings, reboots, or hard faults at all.

1. What S110 version are you using?
2. Are you getting the BLE_GAP_EVT_DISCONNECTED event with any disconnect reason?
3. Do you get any useful information from the logger?
4. Are you staying in connection for a long time or connecting and disconnecting rapidly.
