Testing Lua Blynk lib on Xedge32

Connecting Xedge32 to Blynk Using Lua

I created an Xedge32 to Blynk IoT test program. Xedge32 is similar to NodeMCU in that it provides a Lua foundation for device programming but it’s designed for ESP32 and preferably the new ESP32-S3.

Step 1: Install and Configure Xedge32

Install and configure Xedge32:

Step 2: Download the Blynk Test Program

I’ve prepared a Blynk test program (ZIP file), which you must download:

Step 3: Upload the Blynk Test Program

  • Navigate to http://xedge32.local/rtl/.
  • Spot the three dots in the top right corner. Click them, then select Firmware Update & App Upload.
  • Drag and drop the ZIP file into the browser window.
  • You’ll see an option to “Unpack ZIP file”. Please select it and click Save.

Step 4: Unpack and Configure

The ZIP file will now be unpacked on your ESP32 and appear as an app in the left pane. Here’s what to do next:

  • Expand the app in the left pane and click on the .preload script.
  • You’ll see a place to enter your Blynk authorization token. Insert it between the quotation marks, just like in the screenshot provided.
  • Hit Save.

Step 5: Launch Your App

Almost there! Let’s start the Blynk test app:

  • Click on .appcfg in the left pane to open the app dialog control menu.

  • Press the Running button to start the application.

Step 6: Verify the Connection

If everything went according to plan, you should now see a printout that looks something like this:

        /___/ for Lua v0.2.0
