OSX Catalina was the last version I got to work.
Big Sur is locked down to the point of being pretty useless for our tool chains/apps.
I Dual boot.

Ooooops.
Some Callback processing causes a crash.
Stack size somewhere in Arduino version needs increasing I guess.
The troubleshooting costs might exceed the benefits.

Thanks. I completely missed NimBLE. I saved about 6% program memory. Using BlueDroid Sketch uses 1095047 bytes (16%) of program storage space. Maximum is 6553600 bytes. NimBLE Sketch uses 656243 bytes (10%) of program storage space. Maximum is 6553600 bytes. Notes: If you are using the Arduino re-fa...

A google search turned up this 90+ projects summary.
I haven’t verified everything but I think they have a good reputation.

but also there is the same usb engineering sample to the maker market with an ESP32-S3, which support Wifi and Bluetooth and is based on the ESP32-S3-Mini serie's.

Can’t wait for any news on S3—mini or maxi

Thank you for all your work on this.

I’m just trying that now. I’ve completed the secure BLE side and now adding a simple tcp/ip connection to a non-secure server. But I will try the Arduino IDE first before ESP-IDF since that will appeal to more hobbyist-type people. Which is the audience. If the ESP32 can pull this off, It will be am...

And the takeaway from this exchange is that there is such a thing as the “ESP Journal”

I’m interested in this topic as well.

Dana,
Does the AI-Thinker board have these parts?

For 60 sec. of 16 bit samples 4MB of PSRAM, as suggested above, would work but it has a slow write cycle. I don’t know if it would complete before the next interrupt.
