Sorry for my English, I think that I have not explained properly. I know that the status code 0x0c means that the device could not perform the requested operation to be in a bad state, but I do not know how the device can reach a bad state and what are the possible states. Any help would be appreciated. -- 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
