I am interested by adding a wifi card in my project ... with all the possibilities that it can offer this addition

but my test with a wifi chip is a failure, I tested the chip esp8266 12E, I have not success to make it work properly, I think I chose the wrong model (12E), finally, I nothing against a new test with a good chip

Thanks
