Widget LED, reconnects when closing app

iclimb · May 26, 2015, 1:58pm

Hi.

I’m having a problem with the Widget LED, it seems like bug. I can reproduce it in my own sketch and the Widget LED example.

I’m using ESP8266 (01) and Android.

When i’m using the widget LED and run the sketch everynthing is working just as intended, until i close the Blynk app on my android phone.
Then the ESP runs the loop a few more moments before reconnecting to Blynk server. It keeps trying to reconnect every few moments.
Every second time it reconnects to Blynk server, and every other it reconnects to WiFi network.

the log i get from the Example code is:

Just as a FYI the platform is rebooting.

You would want to copy your code sketch up here not much anyone can do without seeing it.

Also your power clean? You got another one of these chips to test? They are not known to be amazingly stable.

@Spudgunman
Well the bug is the same both in my sketch and in the example for Widget LED. The log i posted was created when running the widget LED example. Code in bottom of reply. The only thing from the Example sketch i changed was:

Adding library for ESP8266
adding SSID and PASS
changing the virtual pin numbers.

Unfortunately at the moment i have no other chip to test. But i don’t think the chip is the problem.
It runs flawless as long as the mobile app is open and connected with the correct Project. As soon as i close the app, or stop the project inside the blynk app, it starts reconnecting.

The Blynk library contains several 3rd party libraries.
You need to copy them manually to your libraries folder.

The structure should look like this:
~\Arduino\libraries\Blynk
~\Arduino\libraries\BlynkESP8266_HardSer
~\Arduino\libraries\BlynkESP8266_SoftSer
~\Arduino\libraries\SimpleTimer

Please check that you have this structure

Robots · December 21, 2015, 5:47pm

Check that your Arduino "Libraries " folder has the same structure:

~\Arduino\libraries\BlynkESP8266_SoftSer
~\Arduino\libraries\SimpleTimer

Too many code. The simplest way to find a problem would be to start from begining. So start from empty Blynk example and tell us if it works. If it works - add step-by-step your code and check every time if it works until above error.
