Ever since I attempted to share my project on my wife’s phone, it has stopped working altogether.
I turned sharing off, updated the Blynk library and also the latest app on my Iphone.
I tried new authorizations and verified my hardware is OK by loading a simple program to turn an LED on and off. The hardware (ESP8266 “Sparkfun Thing”) shows up on my wireless router when powered up, so I’m pretty sure the hardware and wireless is OK.
At first, I switched 'sharing" on on my phone, hit “generate link” and shared that with my wife’s phone via a message. I could not get the Blynk app on my wife’s phone to read the image (see post to Pavel on May 30). The Blynk app attempts to take a picture, and I have no way of printing the link image.
Giving up on this approach, I decided to just create a new project on my wife’s phone, identical to the original. I got the new authorization token (on her phone) and put it into the code on the ESP8266. I could not get this to work at all.
Subsequently, I put the original auth token back into the code to get it to work again with my phone, but with no luck. I then refreshed the code and tried again. Still no luck.
I get no error messages. Routinely, I get a message saying “ESP8266 is offline” when I first activate the project, but it acts the same when the ESP8266 is powered or not powered, so it really doesn’t tell you anything.
Any simple test I can run to verify that my phone is connected to the Blynk server and also that my ESP8266 is connected to the server?
Hello previous blynk app version can share the project using url and but now only qr code is possible.
What if the other mobile device you need to share to is on another country? how is it possible to share??
Do dashboards shared via QR code generate a unique token, or do they replicate the original token?
I’ve been asked to share a QR code for my HVAC / thermostat project. While I’m happy to share the code if it helps someone to more easily reproduce my work, I don’t want share the token, and inadvertently give a stranger control of my hardware.
