I’m a new Blynker . … Started with Python on Raspberry 2A+. Wrote app to open garage doors. All was workin OK. Upgraded to Raspberry 3 after 2A+ shorted out. I took a few months off and now I am unable to get GPx buttons to work. Used reguests library to access Blynk before. Tried using Blynklib but still no progress. Virtual pins read OK. Terminal writes OK. But GPx buttons are inop via Blynk app. They work OK when manually set.
Where to go for help/example/code for my GPx button in python.
Was using private-anon-093dde407a-blynkapi.apiary-proxy.com as Blynk server but I get a hash error on it so now using blynk-cloud.com .
