/**
 * The BM78 module says that the module is ready about 475ms after start,
 * but that the proper thing to do is wait until P1_5 (BT_STATE2) is high
 * and P0_4 (BT_STATE1) is low.
 *
 * This waits for the module to reach this state.  If it fails to become
 * ready after 2 seconds, it enters the error handler.
 *
 * @note This does not work to detect whether the module is ready for
 *  EEPROM programming, only for transparent data mode.  The time required
 *  and state indication for EEPROM programming mode is not specified.
