EspRFTestTool For FCC testing ESP32-S2
Posted: Thu Dec 15, 2022 9:52 pm
At the FCC test lab on Monday we were screening our new product for FCC part 15 subpart C https://www.ecfr.gov/current/title-47/c ... ion-15.247
The test firmware ESP32-S2_RF_TEST_V200_40M_20200714.bin was used on our device. However, when we select TX Continuous in the RD Test Tool, the transmission is about 86% duty cycle.
I checked our device that uses an ESP32-WROOM module with firmware ESP32_RFTest_184_20210927.bin and it does transmit at 100% - which is the expected behavior.
This seems to be a firmware issue in the ESP32-S2_RF_TEST_V200_40M_20200714.bin.
There is a manual tab for entering manual commands. There are some sample commands that when I enter I get better 96% duty cycle transmission. So I know that manual commands could be used to get the required duty cycle for FCC testing.
Does anyone have a list of acceptable commands and what the parameters for WifiTxStart 0xa0000 0 1 0 0 1 or test_rf_cal_level 1 0x1fc000 are?
I have final test next week and I really need this solved.
Thanks,
Mike.
