Hello

I can't compile my sketch or other sketchs found on internet that use ESPNOW on your Firebeetle ESP8266. My sketch is running well on an ESP32 from Azdelivery.

I got this error :

<command-line>:0:19: warning: missing whitespace after the macro name [enabled by default]
/private/var/folders/ml/fhx2h4td5bn6jsqjc2w8n1v00000gn/T/arduino-sketch-254AFB23495B17BEC9862AC214E42AE6/sketch/sketch_sep11b.ino.cpp.o:(.text.setup+0x8c): undefined reference to `esp_now_init()'

All ESPNOW directives I used are “undefined reference”.

I try to add "-lespnow" to the compiler.c.elf.libs line in my ~/.platformio/packages/framework-arduinoespressif8266/platform.txt as suggested by some.

What is wrong?

Regards

BTW I can't send a file.
