Difference between Adafruit NINA FW and Arduino NINA FW

by omar6995 on Tue May 04, 2021 12:42 pm

Hi everyone,

I'm trying to understand how is the ESP32 used as a coprocessor with other uC.

I'm trying to understand how the ESP32 works along with the Wifi Library.

Here is my understanding :

ESP32 and Main uC are connected throught SPI and UART
Main uC is sending throught SPI commands to ESP32 to delegate a few tasks, then ESP32 is answering and sends results

Here are my questions
1-What is the use of UART connection between ESP32 and main uC?
2-What is the difference between Arduino Nina FW and Adafruit Nina FW ? Is it just the pinout which is changing ?

Thanks for your help!

Best regards,

For the First question, I think I found out the answer
1-The UART Connection is used to program the ESP32 for updating its firmware for example ? Am I wrong ?
