Hi.
No.
I2C and I2S are two completely different protocols.

Thanks for your reaction!
Looking now at the Wire.h I see the statement:
#define I2C_BUFFER_LENGTH 128

So that indeed explains the 128byes. I will see if I can edit this file and run/compile again.

Thanks.

There will be some size limit due to the size of the buffer allocated in the Wire library. According to docs.arduino.cc/language-reference/en/functions/communication/wire/ the limit is 32 bytes. Searching for “ESP32 I2C buffer size” indicates it’s probably 128 bytes e.g. forum.arduino.cc/t/what-is-the-wire-buffer-limit-on-the-esp32/649989/3

Hello Ivan, I see something similar (using the i2c link between a ESP8266 and ESP32. On both I use Wire.h. The maximum size seems to be 128Bytes (I only checked it from ESP8266 to ESP32 over the I2C link). I have not been able to find a reason (a tutorial, or e-mails, etc on Google).

Any help is still appreciated (I now split my messages…)

THIS ^^^

You don’t get to redefine industry terms. we have male and female connectors (no non-binary) motherboards and daughter cards, and yes, master / slave processes.

We know it’s nothing but virtue signalling. But the truly sad part is that while you and I just roll our eyes, the people who actually profit from human trafficking today are laughing their posteriors off. They absolutely LOVE the distraction because the more effort spent on bickering about worthless activities like this, the less effort is focused on actually going after them. Slavery is alive in well in the world today in places and forms that would surprise us all, and the ‘masters’ relish these futile attempts to change their hearts and minds. But if someone wants to think they are leading the army against injustice by changing some words in a source file, then gee whiz, I’m sure that’ll really show those bad guys a thing or two!

Hi.
Unfortunately, I didn’t test that.
