BLE UART on ESP32 Controller UART is a Universal Asynchronous Receiver/Transmitter, The main purpose is to transmit and receive serial data. The serial communication stands for sequential transmission or reception of data of one bit at a time through the bus or communication channel. Hence the 5V UART output pin from the VR3 needs to be reduced down to 3.3V for the ESP32 input pin. This is easily accomplished using two resistors. The ESP32 has 3 serial ports. By default the first, U0UXD, is used for the USB serial port, including for programming. The second, U1UXD, is commonly used to connect to an SPI flash chip. The Pi UART walkthrough was very helpful, I think I understand how to get this going on the Pi side. After going through the initial set-up, I then will connect the following pins.

BLE UART on ESP32 Controller UART is a Universal Asynchronous Receiver/Transmitter, The main purpose is to transmit and receive serial data. The serial communication stands for sequential transmission or reception of data of one bit at a time through the bus or communication channel. The idea of the program is to initialise a Serial Bluetooth connection using ESP32 and listen for data from paired devices. If the incoming data is '1' then we turn on the LED and if it is '0' we should turn off the LED. We begin our program by adding the header file BluetoothSerial which makes the ESP32 Bluetooth to work as Bluetoth SSP.

This is a non-shared two-wire protocol with an RX line, a TX line and a fixed baudrate. The most common devices that use UART are GPS units, MIDI interfaces, fingerprint sensors, thermal printers, and a scattering of sensors. One thing you'll notice fast is that most Linux computers have minimal UARTs, often only 1 hardware port. ESP32 has 3 hardware serial ports that can be mapped to almost any pin. But, Serial1 and Serial2 will not work. In case of ESP32 this just has to be done in a slightly different way: The trick is to use HardwareSerial library to access UART 1 and 2.
