Bluetooth Settings connection
Apr 10, 2017

Any Bluetooth device in discoverable mode can transmit the following information on demand:

Any device can issue a connection request to another device, and any device may add a configuration that responds to the request. However, if the device attempting to make a connection request knows the address of the other device, it will always respond to a direct connection request and, if necessary, send the information in the list above. The use of a device service may require the acceptance of a pairing or device holder, but the connection itself can be initiated by any device and continues to the device out of the connection. Some devices will not be able to connect with other devices at the same time as they are connected to a device until the initial connection is disconnected before they can be queried again.
