I still can't get the MKR Env Shield to initialize with a WiFi 1010, running any of the tutorial sketches. Ardunio had me try many things, send them a video of trying and getting stuck at "failure to initialize" from the initial Env.begin() statement.
They had me send back my board, a replacement Env Shield Rev 2 arrived today - same exact problem. Tried multiple WiFi1010s, same problem with new R2 shield across both WiFi1010s.
I ran the blink and simple web server sketches on the WiFi1010s wtihout the ENV shield attached, works fine. But if I attach the ENV shield the LED_BUILTIN on the WiFi 1010 no longer lights on the Blink sketch and WiFi doesnt start up. Seems like Pin 6 is the LED on the 1010 board, and the ENV shield might be using that pin.
I've asked Ardunio if there is something incompatible between the R2 ENV shield and the WiFi 1010 - has any one use a rev2 ENV shield?
Thanks, jojobaa - Joyal from tech support just sent me that link.
I have one of the ones with the silk screened sun symbol with no sensor installed. But, that help piece doesn't say if that is a problem or if there are R2 issues.
After many exchanges with Arduino tech support, they found a problem in the MKR ENV library .cpp file. They sent me a candidate replacement to try and it solved the problem - WiFi1010 and MKR_ENV sandwich initialies and reports temp/humidity/air pressure, light, UV all fine.
When new MKR_ENV library is released, it will include fix.
