There is a official post about ESP-IDF support for new ESP32-S2 features. I found it while looking for WiFi ToF documentation so it's not actually that hard to find. https://esp32.com/viewtopic.php?f=10&t=14532 Still should be in the docs, not some random post. Also, that list hasn't been updated i...

The problem I have is there's no disclaimer anywhere that I can find that USB OTG firmware support doesn't exist. At the very least the API docs should include an entry for it and a note in parenthesis or a paragraph that states it's status. The only real reason I can see for choosing an ESP32-S2 ov...

Seems pretty odd that everything regarding the ESP32-S2 is touting it's USB OTG, yet there is absolutely no support for it anywhere.

It's kind of hard to design a product based on the promise of USB OTG if there's no support for it.

Yes, I did see that, but it wasn't clear to me if a service need only one OACP descriptor, or one for each operation. Part of that lack of understanding was exacerbated by there being no OTS support in the esp-idf libraries. I found a couple of BT devices that do support OTS, and they all only had a...

I've got a BLE profile working nicely, and I'm trying to add Object Transfer Service support for firmware updates. There's one piece (so far...) that I'm having a really difficult time with, and that's how to specify the OACP characteristic table. The BT specs are really opaque, at least to me. Belo...

I'm trying to understand how to determine the values for dma_buf_count and dma_buf_len when receiving (or transmitting...) I2S data. I've read through the i2s_example_main.c, and understand how to calculate the values if I'm synthesizing a waveform, but I don't understand how to determine the values...
