Making UDP latency more predictable, i.e. reducing jitter

Hi all, my application is a low-latency UDP audio bridge using two ESP32-C5 sample Devkits, but I suppose the question can be answered with ESP32-C6 knowledge. I'm using the 5 GHz band with 11ax with the receiver taking the role as AP and the sender is the only station, with nothing in between and n...

Re: ESP-NOW max data rate and security

True - this is why I asked for v2. Compression is not an option, mainly because this is supposed to be a low latency application, and compressing imposes to much calculation effort, and hence, latency. I could simply run a test, no problem, but my main concern is the point #3. Makes no sense to set ...

ESP-NOW max data rate and security

I am evaluating the feasibility of using ESP-NOW instead of UDP for my project which involves low-latency 8-channel audio transmission between two ESP32-C6 or (soon) C5 modules over a couple of meters. The sample rate is 44.1 kHz and I'm going to use an I2S TDM256 format from the ADC in the sender a...

ESP32-C5: maximum number of I2S slots ?

For my project which involves streaming 8 audio channels at 24 bit / 44.1 kHz between two devices I envision using ESP32's over WiFi (UDP or ESP-NOW to thwart latency). Alas, the ESP-IDF documentation says for ESP32-S3 and C6 that "... due to the hardware limitation, only up to 4 slots are supported...
