Re: RAM usage for mbedtls

I once worked around this issue by using BearSSL (see https://github.com/MrBuddyCasino/ESP32_Alexa/). You get ownership of the buffer, and thus don't have to copy. Its not trivial though, and I can't give any assistance. Another option to safe memory is to not use a threading model, but an event rea...

Re: ARM single wire debug with black magic and the ESP32

Nice! Had some trouble flashing BMP to a Blue Pill due to 64k flash limit, this would have saved me some time. Is the port feature complete?

Look at the antenna feed points, the two bright spots on the black antenna part. In Pos 3 & 4, they are at the edge of the board, in all others they are in the middle of the PCB.

Re: I2S Audio Crackling / Pops

On a side note, is it possible to have the I2S driver send silence instead of the last buffer if it receives no data in time? I've yet to come across a situation where a buffer underrun doesn't result in annoying buzzes. Silence would definitely be the preferred output if there's no data. +1 for that

Re: esp32 seems dead

I had three boards die on me before. The usb-to-serial chip suddenly got very hot, maybe because of some unlucky connection I made, and then it remained dead.

Re: ESP32 Webradio

Maybe, it might be possible to allocate or deallocate BT memory once, I'm not sure. You'll have to test it.

Re: ESP32 Webradio

The problem is that Bluetooth consumes a lot of RAM, and the web radio needs a lot of it, especially for AAC. It is currently not possible to dynamically allocate and de-allocate the Bluetooth memory, which makes switching between the two modes during runtime impossible. You might get around this if...
