Nope, btgatt-server doesn't configure anything related to advertising; it simply sets up and attaches a GATT server to a listening L2CAP socket on the ATT channel. So you need to set up advertising separately, e.g. by running 'btmgmt advertising on' or 'btmgmt add-adv'. Note that you usually don't want to run btgatt-server while bluetoothd is running since they will interfere with eachother. > > > Additionally, if I try to run bluetoothd, I get the following output > which doesn't look good! > > > sudo ./bluetoothd -nE > > bluetoothd[19968]: Bluetooth daemon 5.30 > bluetoothd[19968]: Starting SDP server > bluetoothd[19968]: Bluetooth management interface 1.7 initialized > bluetoothd[19968]: Failed to obtain handles for "Service Changed" characteristic > bluetoothd[19968]: Not enough free handles to register service > bluetoothd[19968]: Error adding Link Loss service > bluetoothd[19968]: Not enough free handles to register service > bluetoothd[19968]: Not enough free handles to register service > bluetoothd[19968]: Not enough free handles to register service > bluetoothd[19968]: Current Time Service could not be registered > bluetoothd[19968]: gatt-time-server: Input/output error (5) > bluetoothd[19968]: Not enough free handles to register service > bluetoothd[19968]: Not enough free handles to register service > We really need to clean these up. Basically bluetoothd fails to register all the experimental local services since we changed the internal plumbing to the new shared stack. Fwiw these are all plugins that we are deprecating and the actual local GATT server will work regardless. Also, if you want the daemon running, I suggest using the GATT D-Bus API for hosting your own services. > > I've done plenty of googling and not finding anything useful, so I'm > hoping that someone here will have some insight. > > Thanks, Neil > -- > 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 Thanks!
