org.bluez.error.inprogress 蓝牙错误

Question

I have an issue where the Bluetooth got disconnected after 1-2s of connection, the master side will show the following error:

org.bluez.error.inprogress 

tracing to the log I saw it will enter the following func:

Jun 11 16:23:49 rap kernel: [12110.003936] bluetooth:l2cap_send_cmd:865: code 0x06

and tracing to the code in blueZ:

static DBusMessage *connect_profiles(struct btd_device *dev, uint8_t bdaddr_type,
                    DBusMessage *msg, const char *uuid)
{
    struct bearer_state *state = get_state(dev, bdaddr_type);
    int err;

    DBG("%s %s, client %s", dev->path, uuid ? uuid : "(all)",
                        dbus_message_get_sender(msg));

    if (dev->pending || dev->connect || dev->browse)
        return btd_error_in_progress(msg);  <------------------ HERE
...
}

My question can I somehow know which condition (pending/connect/browse) is causing this error without adding editing the code as I dont have permission to do that? and how come the blueZ will try to connect to the profile if any of this condition is in progress?

Answer 1

Try restarting the bluetooth service. Had an error that said the same and managed to solve it by restarting the bluetooth service.

sudo service restart bluetooth

Try running the above command and see if it helps.
