How to Update Factory Parameters
This document describes how to update the default factory parameter configuration for ESP-AT. The factory parameter configuration includes some Wi-Fi configurations, UART configurations, and module configurations.
Factory Parameter Configuration
The default factory parameters are configured in the source file customized_partitions/raw_data/factory_param/factory_param_data.csv, as shown below:
Function
Current Configuration
Related AT Commands
Wi-Fi Configuration
max_tx_power (Wi-Fi maximum transmission power for ESP32, see ESP32 Transmit Power for the setting range)
country_code (country code)
start_channel (starting Wi-Fi channel)
channel_num (total number of Wi-Fi channels)
All AT commands requiring Wi-Fi functionality
UART Configuration
uart_port (UART port used for sending AT commands and receiving AT responses)
uart_baudrate (UART baud rate)
uart_tx_pin (UART TX pin)
uart_rx_pin (UART RX pin)
uart_cts_pin (UART CTS pin)
uart_rts_pin (UART RTS pin)
All AT commands requiring UART functionality
Module Name
