BCM20702A0 seems very unstable, bringing up the interface with hciconfig hci0 up can result in timeouts . occasional ACL packet errors etc. once interface is up, after a succesfull xfer, restarting a LE advert can also result in timeouts, device also sometimes misses events. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
