For ESP32 GPIO that do not have RTC capability, what is their state in deep sleep? Are they disconnected? Tri-state? Undefined?
I couldn't find this documented in the datasheet.

Re: esp_wifi_disconnect() hangs
The reason why esp_wifi_disconnect() would never return is because I was calling it from an esp_timer callback. Which I guess isn't permitted.
Maybe similar to https://github.com/espressif/esp-idf/issues/4115

Re: ESP32 simultaneous a2dp sink/source?
Hello, any updates on this capability? i.e. Can ESP32 work with a Bluetooth device that has both speaker and microphone?
Thanks,
Carl

esp_wifi_disconnect() hangs
I'm working on a provisioning feature with my code. After successful I stop the provisioning service I then call esp_wifi_disconnect() which never returns.
Where can I find the source code for esp_wifi_disconnect() to troubleshoot?

I2S_write blocks with unfilled DMA buffers
The i2s_write() call blocks when I try to pre-fill the TX DMA buffers. I'd like to fill the DMA buffers before I call I2S_start() to minimize the possibility of underruns. However, i2s_write() doesn't return unless I2S is already started. Upon further testing and inspecting the i2s.c code, it seems,...
