it broadcasts itself if there are no connections to it. example, if i unplug the esp32, the phone will "eventually" pick up the XBT, i say eventually because it may take up to 15 seconds with the app, the esp32 connects in less than a second hahaha
the XBT range should be normal bluetooth range, considering people install the XBT in their engine bays amd use a phone app, the ESP32 should be fine
