Hi @MohamedElmahdy,
After some quick debugging, we figured this is a problem due to github’s Symbolic Link:
, it did not copy itself for some reasons.
We are fixing this right now and will update all the libraries.
For now, you can use the git clone methods to redownload the libraries, and check if Seeed_Arduino_atWiFi/src/AtWifi.h is a complete file.
