build.py menuconfig –> Component config –> ESP8266-specific –> UART for console output –> Default: UART0įind the row of WROOM-02, set uart_tx_pin to 1, uart_rx_pin to 3, uart_cts_pin to -1, uart_rts_pin to -1, and then save the table. Set uart_tx_pin and uart_rx_pin to GPIO15 and GPIO13, or GPIO1 and GPIO3.įor example, if you need to set GPIO1 (TX) and GPIO3 (RX) to be both the log port and command port of ESP-WROOM-02, do as follows: The UART pins can be changed, but there are only two choices: GPIO15 as TX pin, GPIO13 as RX or GPIO1 as TX, GPIO3 as RX. The UART0 pins are defined in Column uart_port, uart_tx_pin, uart_rx_pin, uart_cts_pin, and uart_rts_pin of the factory_param_data.csv. However, you could modify the log port from UART1 to UART0 by:īy default, ESP8266 AT firmware uses UART0 to send AT commands and receive AT responses. UART1 only supports GPIO2 as the TX pin, and the pin should not be modified. Modify Log Port Pins ¶īy default, the ESP8266 AT firmware provided by Espressif uses UART1 to log output.

Please refer to ESP8266 Technical Reference Manual for more details. The log port and command port pins of the ESP8266 AT firmware can be user-defined to other pins, but with limited options. Modify Log Port Pins ¶īy default, the ESP32-C3 AT firmware provided by Espressif uses the following UART0 pins to output log: ESP32-C3 Technical Reference Manual for the pins you can use. The log port and command port pins of ESP32-C3 AT firmware can be user-defined to other pins. Modify Log Port Pins ¶īy default, the ESP32-S2 AT firmware provided by Espressif uses the following UART0 pins to output log: Refer to ESP32-S2 Technical Reference Manual for the pins you can use. The log port and command port pins of ESP32-S2 AT firmware can be user-defined to other pins. Set uart_cts_pin and uart_rts_pin to be -1 if you do not use the hardware flow control function. Set uart_tx_pin and uart_rx_pin as needed. Open your local factory_param_data.csv file. You can change them directly in your factory_param_data.csv table: build.py menuconfig –> Component config –> Common ESP-related –> UART RX on GPIO#īy default, UART1 is used to send AT commands and receive AT responses, and its pins are defined in Column uart_port, uart_tx_pin, uart_rx_pin, uart_cts_pin, and uart_rts_pin of the factory_param_data.csv. build.py menuconfig –> Component config –> Common ESP-related –> UART TX on GPIO#

build.py menuconfig –> Component config –> Common ESP-related –> UART for console output When compiling your esp-at project, you can modify them to other pins with the menuconfig utitlity: Modify Log Port Pins ¶īy default, the ESP32 AT firmware provided by Espressif uses the following UART0 pins to output log: Refer to ESP32 Technical Reference Manual for the pins you can use. The log port and command port pins of ESP32 AT firmware can be user-defined to other pins. To use other interfaces as the AT command port, please refer to AT through SDIO, AT through SPI, or AT through socket for more details.
