Detailed explanation-1: -RTS: Request-to-send–signal to modem, indicating UART wishes to send data.
Detailed explanation-2: -What is UART? UART stands for universal asynchronous receiver / transmitter and defines a protocol, or set of rules, for exchanging serial data between two devices. UART is very simple and only uses two wires between transmitter and receiver to transmit and receive in both directions.
Detailed explanation-3: -We then initialized UART channel 0 with a baud rate of 115200. GPIO0 and GPIO1 are used as TXD and RXD pins respectively for UART communication and initialization.
Detailed explanation-4: -The UART interface consists of two pins: the Rx and Tx pin. The Rx pin is used to receive data. The Tx pin is used to transmit data. When two devices are connected using a UART, the Rx pin of one device is connected to the Tx pin of the second device.
