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.

Re: Reducing memory usage when using BLE
Ooooops.
Some Callback processing causes a crash.
Stack size somewhere in Arduino version needs increasing I guess.
The troubleshooting costs might exceed the benefits.

Re: Reducing memory usage when using BLE
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...

Re: ESP32-S2 ESP32-S3 engineering usb dongle "esp32-sx-stickley"
Can’t wait for any news on S3—mini or maxibut 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.

Re: Speed of Switching between Wifi and Bluetooth
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?

Re: SAMPLING AUDIO - How to handle large data?
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.
