4. RF Performance Test

This chapter takes ESP-WROOM-32 as an example to demonstrate how to use the

EspRFtestTool to run the RF performance test.

Follow the steps to start the test:

1. Conﬁgure the serial port

• Double-click espRFTool.exe to run the EspRFtestTool.

• Choose ESP32 for "ChipType".

• Choose the right port number (COM27 in this case).

•

Set the baud rate to 115200.

• Set the status of the serial port to "open" (the port can switch between statuses).

2. Download the ﬁrmware

• Select the BIN ﬁle to be downloaded. ESP32_RF_TEST_BIN_V1.3.1_20180115.bin

is downloaded in this document.

•

Choose the download address: RAM or Flash.

• MAC address: The status block shows the MAC address of the chip. For ESP32, the

STA and BT addresses appear; while for ESP8266, only the STA address appears.

• Click on "load bin" and start the downloading process. "SUCC" will appear if the

downloading process ﬁnishes successfully.

• If the ﬁrmware is downloaded into ﬂash, leave GPIO0 ﬂoating and re-power on the

module after successful downloading. If the ﬁrmware is downloaded into RAM, run

the ﬁrmware directly, without leaving GPIO0 ﬂoating or re-powering on the module.

3. Run the RF test

3.1 Wi-Fi Tx performance test

1. Choose "wiﬁ Test" in the test's conﬁguration section.

📖 Note:

If the BIN ﬁle is downloaded to ﬂash, users need to download it only once, unless there is a later version of

the BIN ﬁle.
