WFA Certification code

[Ugljesa]

Hello,
We need to perform CE and WFA certifications on a closed device. We don't have access to the debug port and it is not possible to have a PC connected to the device. Is it possible to get the source codes of the bin files provided at: https://www.espressif.com/en/products/d ... esources?7 (ESP RF Test Tool and Test Guide and ESP8266 & ESP32 WFA Certification and Test Guide) so we can integrate it in our FW or an explanation of the procedure and the used APIs?
We have OTA update active, can we somehow use that channel to download the binaries. What options do we have in that case to perform the setup that is done by PC?
