6.2.2. ESP8266 AT

If users download the ESP8266 AT ﬁrmware, or the default ﬁrmware in ESP-LAUNCHER or

ESP-WROOM-02U, the system in working mode will display “Ready” at the end. Input

command “AT” in the terminal and the system will return “OK”, which means that the

ﬁrmware works properly.

6.3. Conﬁguration of RF initialization (Optional)

Before downloading binaries to ﬂash, users can modify the RF initialization settings in the

RF InitConfig tab. The newly-generated esp_init_data_setting.bin can be downloaded to

the ﬂash instead of esp_init_data_default.bin. Users can conﬁgure both the options and

the parameters of the RF settings.

📖 Notes:

• The baud rate in AT ﬁrmware is conﬁgured as 115200 manually, however, the default baud rate of

ESP8266 is 74880, due to this discrepancy, the system initialization information will be displayed as

mojibake. It is a normal phenomenon as long as the system shows “Ready” at the end.

•

For more information on AT commands, please refer to ESP8266 AT Instruction Set.
