Yeah, it`s better when support L2CAP. If the channel is only use for logging, can we delete it? There are only two functions calling find_service, one in your commit , another in register_record function: service = find_service(driver, 0); Seems the channel parameter is useless. And considering OBEX over L2CAP, should we modify find_service to static struct bluetooth_service *find_service(struct obex_service_driver *driver) just delete uint8_t channel parameter. If ok, you or me can upload a patch for this issue. Nami ?韬{.n?????%??檩??w?{.n???{饼?z????n?■???h?璀?{?夸z罐?+€?zf"?????i?????_璁?:+v??撸?
