<![CDATA[Arduino get_apikey()]]>Hello,

I am working with an M5StickCplus.

In micropython one can obtain a unique device ID like this:

import deviceCfg
deviceCfg.get_apikey()

How does one get this same key in Arduino? Is this only a feature of UIFlow or is there some equivalent other hex identifier?

Thx, PD

Do you mean the hardware MAC adress? It is (theoretical) unique on every piece of network hardware.
WiFi.macAddress()

Do you happen to know if there is any way to obtain a char[] or int that is unique to each M5stickC in Arduino? If one has many devices sending data over wifi, is there any way to tell them apart other than hardcoding a string or using a hardcoded IP address? Cheers, PD

Arduino wipes the firmware and works on a lower level to Micropython
