Hi folks,
any solution or hints for this issue? I run into the same problem.

Kind regards,

When compiling the WiFi module, the make command doesn't appear to be finding the esp_timer.h file located in LuaNode32/main/include. So, my temporary solution was to simply:

cd LuaNode32
cp -rp main/include/* components/modules
