Hi guys, I came across this thread while trying to fix some M5StickC issues and thought I could chime in with some useful info. You can use Arduino as an ESP-IDF component however, it currently only works up to v3.2.3 of ESP-IDF. If you install v3.2.3 you can then use Arduino as a component from this repo here. Hope this helps.

@rob-biernat It can be hit and miss. Sometimes code on existing function changes resulting in broken code. You can try it but just be mindful of the issues the change may bring.

I have no control over the ble server device. It appears the ble libraries are just flaky

https://github.com/m5stack/GoPlus/blob/master/src/src.ino this is sourece code

@rob-biernat I have some stuff so will try a test this weekend but something else I did think of is the power required to run lots of devices.

No need to cut wire, you can use Dupont jumpers or use grove to dupont male connectors. https://www.seeedstudio.com/category/Grove-c-1003/Grove-4-pin-Male-Jumper-to-Grove-4-pin-Conversion-Cable-5-PCs-per-Pack.html This is what I was using on my M5Stack Black.

@rob-biernat I’m working on a potential divider project which I’m recording to make a guide in taking a design to a finished product. I will be sharing this guide but I’m using a 25W resistor just for its big size!

@rob-biernat which M5Stack or Stick are you using? The M5Stacks and Sticks have an I2C grove port (port A) but this is also a digital I/O port in that it can read or write 0 or 1 values (on or off) I am currently triggering a relay unit from the port. The M5Go base has has 2 additional port which are multi I/O (port b) and UART (port C) Unlike Arduinos, the esp32 which powers the M5Stack has no set pin functions and all pins can be used for a range of functions. When using Port A Yellow is SCL (pin 22) and white is SDA (pin 21) and need to be defined. I have started to document the different functions of the grove connector and you can find them on pg 19 and 20 of my WIP book here https://github.com/Ajb2k3/UIFlowHandbook/blob/master/UIHB1404192.pdf

There is also my ongoing project which is creating a book and the project to create a custom servo module!
