I found this answer from Vudentz on github :
Looks like it is a link layer issue as the connection just times out when we attempt to exit sniff mode:
HCI Event: Disconnect Complete (0x05) plen 4 #18605 [hci0] 358.578948 Status: Success (0x00) Handle: 256 Reason: Connection Timeout (0x08)
Perhaps the device doesn't like that we are exitting sniff mode on our own or something like that.
