     * Test if bonded BR/EDR device can reconnect after BT restart

     * <p>Prerequisites:

     *

     * <ol>

     *   <li>Bumble and Android are not bonded

     * </ol>

     *

     * <p>Steps:

     *

     * <ol>

     *   <li>Bumble is discoverable and connectable over BR/EDR

     *   <li>Android pairs with Bumble over BR/EDR

     *   <li>Android restarts

     *   <li>Bumble is connectable over BR/EDR

     *   <li>Android reconnects to Bumble successfully and re-encrypts the link

     * </ol>
