Thanks again for all the clarification

You probably will learn this hard way, but as far as i know esp32 wont handle that big application. IIRC limit is around 3MB.

As I have said in another thread,, idf.py menuconfig don't work form me. So,, which "step" am I missing ??? (As far I know, WiFi should be a valid component) Who told you idf.py menuconfig wont work? Maybe it is misunderstanding and it was about plain arduino project? The idf.py menuconfig has some...

Are you using example from my repository by any chance? That repository is mark as archived, because USB host API in esp-idf evaluated and here you can find new library with examples which works with esp-idf master: https://github.com/chegewara/esp32-usb-host and here is docs if you would like to wr...

Draining the battery is not a problem for me. Maybe not for you, but for mobile devices that will do the scan. Like i said, the whole point of BLE vs classic BT is to not drain battery, thus the name (LE stands for low energy). Imagine the case where your ESP32 board is lying in a field in the midd...

There is no point (and no option) to change advertised data every 1ms. Why: - usually applications that scan/search for beacons do it with rate 100ms+, why? thats the whole point of BLE, to not drain battery with scan and/or advertising, - i dont remember now from top of my head, but minimum scan/ad...

1) there is BT classic HID host and HID device API in esp-idf already for quite some time as far as i know, 2) i dont want to argue, but i believe new version of PS4 controller is using BLE As to esp-idf, here you can find examples: https://github.com/espressif/esp-idf/tree/master/examples/bluetooth...

It all depends how you build binaries. When you are working with esp-idf and build with "idf.py build" then after success build you can see output similar to this (its from linux): /home/chegewara/.espressif/python_env/idf4.4_py3.8_env/bin/python ../../../components/esptool_py/esptool/esptool.py -p ...

Not deleted, just changed folders structure:

Thanks for your idea. Yes that's probably a workaround for hobbyist. But you will end up with 4 cores MCU @ 160MHz along with 2 SPI Flash memories draining lot of power, As you maybe know there is esp32 SOLO with just 1 core (and maybe embedded flash). Bluetooth is also able to work with MCU @ 80MH...

You can always use S3 + old esp32, which is not that much expensive.
