5. RF Certification Test
ESP8266 and ESP32 share the same RF certification testing process. This chapter takes
the ESP32 RF certification test as an example.
The test BIN is ESP32_RF_TEST_BIN_V1.3.1_20180115.bin, and the baud rate is
115200. Follow the instructions in chapter 4 to configure the serial port and download the
firmware.
