ESP32 Run multi application

[huybk213]

Hi everyone,

My idea is running multi application in flash.
For example, i have 3 application.
One is factory reset, second is bluetooth classic application, and third is bluetooth low energy application.
I'm trying to make wifi, ble and bluetooth audio co-exist, but performance is so bad.
So i want to run only once app at specific time.

If i want to use Bluetooth audio application, i think i will wirte code that change boot partition in flash.
But i do not know how to do it.

My question are:
1. How to flash 3 application into 3 partition in flash, using make flash or esptool.py
2. How to change boot partition?
3. What is the partition.csv look like?
Please help me, thank you so much?
