ESP32 Forum

Hi,

We are working on a design and the ESP32 will be co-located with several other radios. Under the FCC's requirements, we'll need to conduct a seperate certification on the ESP 32.

We need to be able to send a continuously modulated transmission off the Wi-Fi & BLE radios across the low / middle / high channels of each range (2402 / 2440 / 2480MHz).

How can we drive the Wi-Fi & BLE radios for EMC testing in this scenario?

Is similiar access available if we used an ESP 32 module, since we'll need to re-test also for co-location.

Hi WiFive:

Thanks for sharing the link.

But the BLE RF test provided needs UART interface to be connect to control the freq of RF emitted, also it needs GPIO0 floating to be started up.

Unfortunately, our product don't have UART interface exposed for connection during the test and the GPIO0 is pulled high to Vdd, making staffs in test lab not possible to do the test.

Is there any API that we can called to emit one RF frequency on powered up? We can send three samples, each with different emit frequency to the test lab.

Thanks,
Man

Interested in this as well.
Have you found a solution?
