Re: ESP32 roam behaviour
This might get tricky if I want to continously send data over WiFi and also have to think about roaming. If I have to do an esp_wifi_scan_start() every 1-5s, just to see if there is maybe an AP with the same SSID but with a better RSSI in reach, I'd assume that I can't send any data while the scan i...

Re: Read from I2S without blocking call
Assuming i2s_read() is on thread A and the output via http is on thread B.
Both threads do not run at the same time, but only consecutively.
So you still und up with thread B not running because it needs to wait for the blocking call of i2s_read() in thread A to complete.

Read from I2S without blocking call
There are various examples how to read from an I2S microphone. eg: https://github.com/maspetsberger/esp32-i2s-mems However, they all are using i2s_read() https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/i2s.html#_CPPv48i2s_read10i2s_port_tPv6size_tP6size_t10TickType_t ...
