WiFi Continuous Wave for Signal Strength Testing.

I want to be able to send a continuous wave over the WiFi in my application code.
I know there is a binary that is used for FCC testing but I'd really like to be able to do this within my application code.
Could I get some source code or get pointed to some resources for doing this?
Thank you!

Does anyone have anything on this?

If you really need this for production you may want to request engineering support through sales.

Hello! I have the same issue, for EMC (europeen FCC) certification of the ESP32 I need to set the ESP32 wifi as an continus 2,4Ghz emission (independent of the Channel (1-11)).
I hope @jessib have an answer in mp, do you have a bin or the source code to use the esp32 as a 2.4Ghz emetter, only the carrier Frequency, no data, no frequency modulation
plz <3
sincerly
Stan

We recently applied for pre-compliance testing of our product having ESP32- Wroover module. It was our first experience with such testing so agency demanded continuous transmission code with maximum power transmission. We got the .bin file from official website. Module started continuous transmission but tx power setting details is not available in public domain. Please provide some information for TX power setting or what is the default tx power in .bin file for radio performance test folder. This has hold our production plan so looking forward for quick solution.
Thank you.

You're probably better off mailing
sales@espressif.com for this, as they handle commercial requirements more often.

Hello,
could anyone get answer on this thread, on how to transmit continuous carrier wave for max power measurements on 2.4 GhZ?
Regards
Nikhil

There is a radio testing firmware and configuration tool provided by espressif:

The radio test firmware is great, but unusable unless your product happens to have the io exposed as required...Providing source code or having the firmware read test commands from a spiffs config file (if providing source code is not an option) would be an immense help.

I agree - this is something that is causing me a bit of trouble as I will need to make significant modifications to enable radio testing via serial interface.
Is there a spec for communicating with the rf firmware, or as you say - some source code for the test software.
