Yes, I added a switch widget and used virtual datastream if I remember correctly.

I deleted the switch in attempt to troubleshoot and I am now trying to just use the blank Blynk provided template ā€œESP8266_Standaloneā€ and if I use:
Blynk.begin(auth, ssid, pass);
I get an invalid authentication code error which is why I switched it to:
Blynk.begin(auth, ssid, pass, "blynk.cloud", 80);

because that was what was working before. However, now the code is not getting past the Blynk.begin() function because if I put a serial print statement before and after the code, it prints the first but not the second. See below.

Also thanks for the help!

  Change WiFi ssid, pass, and Blynk auth token to run :)
  Feel free to apply it to any other example. It's simple!

Look at the datastreams that you have in the template you are using and provide the actual details.

The Blynk 1.x.x library will automatically compile the code so that it connects to the new IoT blynk.cloud servers, provided it sees:
#define BLYNK_TEMPLATE_ID "Your template ID in here" as the first line of your sketch.
This isnā€™t working, because youā€™ve left this line commented-out, rather than pasting your credentials from the firmware configuration screen for the device in the web console.

Probably because the Blynk.begin process with IoT requires a template ID to be passed to the server as part of the connection negotiation process, and you havenā€™t provided one in your sketch.

Hi,

I had the same problem. In my case it worked when I used the Library version 1.0.1. The newest 1.1.0 caused the same WatchDog errors on my NodeMCU. I was using the latest ESP8266 Core (version 3.1.0)
It was also very important to have the template ID as the first line (even before any include), which was mentioned here before.

Please fix this issue with the version of the library and the NodeMCU (maybe even other ESP8266, haveĀ“t tested it though)

Are you using any Digital datastreams?ā€¦

Pete.

Hello,

you are right that was the problem. I didnĀ“t realize it but I changed the datastreams the same time I changed the version. It now works with the latest version when only using virtual datastreams.
