Re: Flash ESP32 programmatically using Java/Android
To upload the .bin to the esp you would need to control the reset and the boot pins as well. Then you can transfer the .bin through uart0 using the SLIP interface.

Maximum number of open files
What is the maximum number of open files that we can have at the same time with esp-idf, and what are the configurations to get to this value?
currently we can't open more than 5. Is there a way to increase this number?
