Updating esp-wroom-32 through stm32f4

Postby AntoineW » Wed May 23, 2018 11:22 am

Hello,

I'm planning on using the esp-wroom-32 connected to a stm32f4 chip through UART1 in a production environment.
I've read everywhere that the best way to flash the WiFi chip was to use esptool.py but for reasons, I don't like this solution to be put on the production line.

So is this the only way to flash the chip ? As I can control the pins from my stm32f4 chip, I would really like to be able to :
1) Flash it in the first place from it
2) Be able to update the WiFi via the stm32f4 through UART1
Is it in anyway possible ? If yes, I haven't found the procedure to do so, or any examples in C or C++, or even mentions of such cases.

Thank you for your answers !

Antoine
