Remote sensing of GoPro from its blinking LED?

[Gerald]

It communicates with Wifi. (I can see the Yoctop on my Android wifi connections and that is the method of updating the Yoctop). Inside the Yoctop is an Espressif ESP32-WROOM-32U which is supposed to be "powerful, generic Wi-Fi + Bluetooth + Bluetooth LE MCUmodules that target a wide variety of applications, ranging from low-power sensor networks to the most
demanding tasks, such as voice encoding, music streaming and MP3 decoding."

I have no idea of the code in there.

If the GoPro communication protocol is known, you may use a cheap ESP module and then try to write code to do just that. A PIC with WiFi is too much...

There is a Basic Interpreter for ESP modules and you can find it here https://cicciocb.com/forum/viewforum.php?f=1 and in the forum a lot of people can help on the ESP thing.
