as a newbie to Mysensors and platformio this took me a while with the same problem.

The solution (like described above, but not understandable for me at first) is:

platformio.ini add 
lib_deps =    https://github.com/mysensors/MySensors.git#development

which currently links to Mysensors 2.3.2-beta #ea093e5

and the errror is gone :)

Hi mfalkvidd,

thanks for your answer. Today I realize, that I must have been very confused yesterday and mixed up some things and wrote some BS....

To clarify for me and others: The ESP has built-in BT and Wifi interfaces. There are no additional nordic NRF whatever peripherals :)

Also the Philips Hue uses Zigbee, which is not Bluetooth-compliant.

However are there more examples how to use the ESP32 in a MYSensors environment? Could not find much about the interfacing between Node and Gateway...

thank you for your answer

I guess I accept the challenge and keep you posted :)
