Ballscrewbob,
I followed the steps you went through in your video. I see in your video in the WiFi101 Firmware/Certificates Updater you are able to select WINC1501 Model B (19.5.2) firmware. When I get to that step I am only able to select WINC1501 Model B (19.4.4) firmware. I have version 1.8.1 of the Arduino program. Any idea why I am not able to access version 19.5.2 of the firmware?
