Radio Smart LED Strip
This document will guide you through the Radio Smart LED Strip project. You will be able to interact with your LED strip in Node-RED and Blynk and control Power appliance using 16A Relay.
Block Concept
Requirements
-
Either Control Set, or individual components:
- 1x Cover Module
- 1x Core Module
- 1x Power Module
- 1x AC/DC ADAPTER 5V/4A (or higher current rating)
- 1x 3D printed enclosure BCE301
-
Other components:
- 1x Radio Dongle (not included in the kit)
- 1x RGB or RGBW Digital LED strip (not included in the kit)
- Micro USB cable (not included in the kit)
-
One of these options:
- HARDWARIO Playground installed (recommended) You can find more information in the Quick Start Guide document.
- Raspberry Pi with the HARDWARIO Raspbian distribution You can find more information in the document Raspberry Pi Installation.
- HARDWARIO Firmware Tool installed You can find more information in the document Toolchain Setup.
Firmware Upload
In this procedure we will use the HARDWARIO Playground to upload firmware to the Core Module.
Step 1: Connect the Micro USB cable to the Core Module and your computer
Step 2: Flash firmware
Run the HARDWARIO Playground. In the Firmware tab choose and upload the bcf-radio-power-controller- firmware to the Core Module:
If your LED strip is 144 LEDs RGBW:
bcf-radio-power-controller-rgbw144
If your LED strip is 150 LEDs RGB:
bcf-radio-power-controller-rgb150
If your LED strip is 72 LEDs RGBW:
bcf-radio-power-controller-rgbw72
warning
Flashing Core Module R1 & R2 For differences of flashing older Core Module 1 and newer Core Module 2 please read Core Module R1 and R2 comparison in the Hardware section
Step 3: Remove the Micro USB cable from the Core Module and your computer
success
At this point your firmware is successfully uploaded
Hardware Assembling
See short video with easy step by step demonstration:
Step 1: Start with the Power Module
warning
Make sure the Power Module does not have power adapter inserted.
Step 2: Plug the Core Module on top of the Power Module
Step 3: Plug the Cover Module on top of the Core Module
Step 4: Put assembled modules into the enclosure BCE301 and fix it with O-rings
Step 5: Connect the LED strip to the pluggable socket on the right side
Step 6: Connect the 5V DC Power Jack
Playground Bootstrap
danger
If you are using the new HARDWARIO Playground, then use the Functions tab instead of using http://localhost:1880/. Also the pairing process is now done in Devices tab. For communication test use the Messages tab.
Step 1: Open Node-RED in your web browser
Step 2: You should see the empty workspace with Flow 1
Step 3: Insert the following snippet in the flow (using Menu >> Import >> Clipboard) and click in Flow 1 tab, then deploy

It will look like this:
info
This snippet provides control buttons for gateway/radio commands. These commands are sent over the MQTT protocol.
Step 4: Deploy the flow using the Deploy button in the top-right corner
Step 5: Open the debug tab
info
In the debug tab, you will be able to see all the MQTT messages.
Step 6: Click on the List all gateways button. You should see a response like this in the debug tab
success
At this point, you've got working Node-RED, MQTT, HARDWARIO Radio Dongleand HARDWARIO Gateway.
Radio Pairing
In this section, we will create a radio link between the Radio Dongle and the Radio Smart LED strip.
Follow these steps in Node-RED:
Step 1: Click on the Start node pairing button
Step 2: Connect the power adapter into the Radio Power Controller to send the pairing request (you should also see the red LED on the Core Module to be on for about 2 seconds)
Step 3: Click on the Stop node pairing button
success
At this point, you've got established a radio link between the node (Radio Smart LED Strip) and the gateway (Radio Dongle).
Communication Test
Follow these steps in Node-RED:
Step 1: Switch to debug tab on the right
Step 2: Insert the following snippet in the flow (using Menu >> Import) and click in Flow 1 tab

Step 3: Edit set node id node, and change "Replace with" to your node id, e.g. kit-power-controller:0 (you can find your node id by clicking on List paired nodes)
Step 4: Press led-strip set color #ff0000
Integration with Blynk
Now we have assembled our Radio Power Controller and let's start with some basic integration with Blynk. We will start without describing what Blynk is. If you want get some information about what Blynk is. The best thing you can do is to visit their page. In our example we will be showing you how to control LED strip colours in Blynk's mobile application.
Firstly we need to configure our Node-RED app.
Step 1: Blynk nodes
If you are using HARDWARIO raspi version you should be fine, but still check that Blynk nodes are installed. (You can view them on the left side menu in Node-RED). Otherwise you will need to install Node-RED package node-red-contrib-blynk-ws.
Step 2: Add another flow (you can add them by big plus button next to the flow name)
Step 3: Insert the following snippet in the flow (using Menu >> Import >> Clipboard) and click in Flow 3 tab

It will look like this:
Step 4: Configure Blynk connection
Configure MQTT node to connect it on you broker. It will propably connect on localhost if you are using Raspberry Pi. After that you will need to configure Blynknode. Just fill in URL ws://blynk-cloud.com/websockets. The Auth Token we will configure later after obtaining one from Blynk over e-mail.
Step 5: Mobile app
Now download the Blynk app from App Store or Google Play. Create an account and log-in.
Step 6: After installing, you should create account, login and you should see something like that
Step 7: Now click a button on the top right to scan QR code
Step 8: Now you should scan following QR code to get everything preconfigured
Step 9: You should see something like this
Step 10: Email
Click the settings wheel and you should see settings for your project. We need to get Auth Token which you have to copy to our Node-RED in Blynk node configuration.
