Sorry, I do not.

What makes you doubt that? As usual with WiFi/BL coexistence, performance will be impacted (depending on what you try to do) but to my knowledge there's no reason it won't work.

RESERVE_INTERNAL means that there is a pool reserved for allocations that *need* to be in internal memory, for example because they're used in DMA transfers. 'Normal' allocations will not touch this pool, the memory in here is only given out if an allocation specifically requests internal memory.

Can you also say what the issue was and what the solution was? It's a bit frustrating if someone from the future has a similar issue and just reads 'CLOSED" here instead of what you ran into.

At the moment, that is not possible.

Your description doesn't make sense. Data buffer for what? What are you trying to do in the first place, as in what's the bigger picture, what problem are you trying to solve? okay, I think it was not clear enough, I need to process the audio signal packet before the sound is modulated in the DAC, ...

2. separate/isolated I2C bus.

What do you mean by this? The ESP32 already has 2 I2C peripherals, why would you want a 'separate' 3rd? Or do you mean galvanically isolated?

The ESP32 has a fractional baud rate generator. The calculation of the divider for this is (apb_clk*16)/baudrate. The apb_clk normally is 80MHz. So e.g. for 115555 baud, you'd get a divider of ((8000000*16)/(115555)) = 1107.698. Because this number needs to be integer, it's rounded up to 1108, which...

The CLK, SDx, etc lines you connected your ADS1220 to are used to connect the ESP32 to its flash chip, where the code is stored. (See e.g. the datasheet of the ESP-Wrover for the connections.) Suggest you use different pins; at the moment there's no software support for using the flash pins for anyt...
