trying to compile firmware for the 8x dev kit as described in:
but running in the compilation issue:
Sketch uses 1375781 bytes (104%) of program storage space. Maximum is 1310720 bytes.
Global variables use 62800 bytes (19%) of dynamic memory, leaving 264880 bytes for local variables. Maximum is 327680 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board Adafruit ESP32 Feather.
Obviously, we are running out of the available HW resources.
I have tested a build on my own (not the binary provided by Bosch) a time ago (think I have used the lastest libs and Arduino ESP core) and run in the same issue. But you can change the default partition scheme and free so more application space. I don't remember what option I use then, but it compiles and could be upladed after changing partition scheme. Is there any recomendation from Bosch?
