As a side note. The 16 HCI devices limit is not fixed actually. You can just compile your own libbluetooth with a different limit. The kernel supports as many devices as you have memory :) Regards Marcel -- 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
