I have a Arduino MKR WiFi 1010 which appears to be supported by Blynk, however it does not appear in the drop downs, Arduino MKR1000 with a WiFi 101 shield seems to be the default. I’m having difficulty compiling with these settings.
I’d suggest starting with Edgent as it’s fairly difficult to add-in the Edgent provisioning features later.
In the Arduino IDE open Tools > Examples > Blynk > Edgent and select the MKR1010 Edgent example.
If you don’t want to use Edgent then open one of the WiFi examples.
Blynk expects the MKR1010 certificates to be up to date, so you may need to use the WiFi firmware updater to achieve this.
