Hi Pete,
even though I dint want I was spending quite some time yesterday with forensic work on the Blynk libraries (latest version, 1.01) to find why Arduino Wifi Rev2 can not work with Blynk.Cloud and Blynk library (>ver 0.61). Looking at the specific error during compliation I got I was able to identify one specific library:BlynkParam.h inside …Arduino\libraries\Blynk\src\Blynk
The library BlynkParam.h shows two lines of code: return atoll () but in fact atoll does not exist, it is return atol (). When changing two entries in this specific library (return atoll(buff) to return atol(buff)) my Arduino wifi was up and running I got an email from your Maria stating that my device is online, I see my device in the cloud and I was able to upload your demo code Blynk Simple Demo with successfull mobile app interaction. May I ask you to verify if atoll () was indeed a spelling error and should be replaced by atol(). At least it worked well for me. Thanks, Andreas
