// BLUETOOTH SERIAL ON ESP32
// On ESP32 you have the possibility to use the builtin BT serial to connect to
// the CS.
//
// The CS shows up as a pairable BT Clasic device. Name is "DCCEX-hexnumber".
// BT is as an additional serial port, debug messages are still sent over USB,
// not BT serial.
//
// If you enable this there are some implications:
// 1. WiFi will sleep more (as WiFi and BT share the radio. So WiFi performance
// may suffer
// 2. The app will be bigger that 1.2MB, so the default partition scheme will not
// work any more. You need to choose a partition scheme with 2MB (or bigger).
// For example "NO OTA (2MB APP, 2MB SPIFFS)" in the Arduino IDE.
// 3. There is no securuity (PIN) implemented. Everyone in radio range can pair
// with your CS.
