Hi psychoacoustic,

I love the look of the visualiser you created. I'm working on somthing similar but instead outputting the data to LEDs.
I'd really interested to hear how you implimented a Constant-Q transform if it's something you'd be up for sharing.

This feature of receive audio data from bluetooth and then broadcast to other mesh nodes is not supported yet. But we have exploit a related feature: bluetooth beacon, it can be used in sales promotion, and the feature will soon be released. Hi Sam. I'm working on a project that might potentially r...

Until someone chimes in with a better solution, here's how I'm currently solving this problem. My main issue here is that the core mesh firmware is closed source and so I'm having to rely on the limited callback returns. In my event loop event_loop_cb , I create the following case: // If a network i...

Context: I have a few hundred devices which are currently connected to a single access point. I'm sending commands, files and OTA updates to these devices, but because they are all connected to the same access point there is a lot of contention and other network issues. My goal is to use ESP-MDF to...

With the old GNU Make build system, compiling my projects with would drastically reduce my build time from minutes to seconds. How can I do this with the idf.py CMake build system?

For context: I'd like to stream video from one ESP-32 with a Camera to another which has an LCD display. I've figured that ESP-NOW is probably the best protocol to it's lack of overhead.

What's the maximum speed that I could get out of ESP-NOW?

I have been developing a sound visualisation project using the FFT function from the ESP-DSP component . Audio is captured using an INMP441 which is then passed to the FFT function. I am getting great data for higher frequencies but low frequency input cause a bunch of unwanted data to appear at hig...
