Re: I2S sound recorder using only ULP - Possible?
The ULP cannot access I2S or SDMMC peripherals, so you would need to do this all in software. This is not a trivial task, if even possible given the limited speed and memory of the ULP. Light sleep might be an option, given you have 5mA to work with. I'm not familiar with I2S but if it can operate i...

In your backtrace, "operator new(unsigned int)" leads to abort, which is a strong indication that you're out of memory.

Re: CORRUPT HEAP after reconnect
Can anybody confirm that bug? I commented in your GitHub issue, I'm getting it too. In my case the ESP32 provides an AP and HTTP server for configuring WiFi connection and so forth - pretty typical scenario - and when the ESP32 does a WiFi scan for access points, my laptop often disconnects and rec...

Re: Using OTA with multi-partition application
If these files are so tightly coupled with the firmware, embedding them in the firmware might be more suitable than a separate SPIFFS partition. Does the firmware function properly without the files? If not, I would suggest they must be embedded in the binary. Are they ever altered, except in the ca...

Re: I2C ULP
What happens if you remove esp_sleep_enable_ulp_wakeup or I_WAKE? Suspecting the repeated initialisation while running is breaking the I2C or ULP.

Re: Problem sending data in json format using at+httpclient in put
Some of these escape sequences don't look right. Double check the quoted part above.
Use something like https://webhook.site to check that the server is receiving what you expect.

Re: esp32 pico brownout level
It will be exactly the same. It's still the same ESP32, just packed into a tiny module. It will specify a higher minimum voltage due to the integrated flash, which typically has a higher minimum than the ESP32 itself. The same will be true of WROOM modules, for example. So there will be a ~500mV win...

Re: WiFi switch without disconnect.
Unfortunately no, at the moment I must disable the Wi-Fi network everytime I want to switch modality. I hope someone will help me to clarify how to do this. Do all of the initialisation once, and I would include configuring your AP in this. You can create your AP netif something like this: ESP_ERRO...
