Hi there!

Setting this app is a bit of a tech adventure, but don’t worry — I’ll guide you through it.

There are two things to keep in mind:

- You’ll need to pick the right LED controller. Most are unbranded Chinese devices, so a little care helps.
- Android and Google TV have some quirks with Bluetooth Low Energy (BLE) devices. You might need to check some details about your device using a PC or an Android phone.

Don’t worry — below I’ll walk you step by step on what to do next, so you can get your LEDs working smoothly.

# LED Controller/Strip Choosing Guide

Picking the right LED strip can feel tricky, but it’s easier once you know what to look for. Here’s a simple guide to help you choose the best strip for your setup.

On marketplaces like **AliExpress** or **Amazon**, you’ll find countless non-branded kits that include a **controller and LED strip**, sometimes bundled with a simple IR remote.
They may look different and be sold under various names, but in reality they are usually the same hardware.

Most of these controllers work with several popular mobile apps (this can also help you identify compatible devices):

- Lotus Lantern, Magic Lantern
- DuoCo Strip, DuoCo StripX
- LED LAMP
- HappyLighting
- Magic-LED
- LED Hue
- BanlanX
- Colorful Lights
- MR Star

Here’s a concise, effective search prompt you can use on marketplaces like AliExpress or Amazon:
'led strip bluetooth 12v'
You can add the app name like 'Lotus Lantern' etc.

### ✅ Recommended Options
- Choose a kit that includes **Bluetooth connectivity**.
- Use an **external power supply** (not USB).
- Prefer **12V or higher** LED strips — they’re brighter and more durable.
- Enough lenght for your TV/table

### ❌ Options to Avoid
- USB-powered LED strips.
> While they technically work, they are limited to **5V**, which makes them too dim.
- RGBW, RGBCCT, RGBWW or addressable strips.
> They may work but officially not supported yet.

# How to Connect
1. Power on the LED controller.
2. Obtain the MAC address of your controller (if you already know your LED controller’s MAC address, you can skip ahead to step 4.):
- Scan for Bluetooth Low Energy deivces
-- Android phone: use nRF Connect app: [Google Play](https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp)
-- Windows: use nRF Connect for Desktop: [www.nordicsemi.com](https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-Desktop)
-- Linux:

    bluetoothctl
    [bluetoothctl]> scan on

> Note: iOS devices are not suitable because they cannot reveal the real MAC address when scanning for BLE devices.
- The device may appear under one of the following names (or something similar):
- `ELK-BLEDOM`, `ELK-BLEDOB`, `ELK-HR-RGB`
- `MELK-OA`
- `LED-DMX-00`, `LED-DMX-03`
- `Triones`
- `SP105E`, `SP110E`, `SP611E`, `SP621E`
- `Colorful-Light`
- `GATT--DEMO`
- Find the device’s **MAC address** — a sequence of six hexadecimal numbers separated by colons (example: `XX:XX:XX:XX:XX:XX`).
3. Open the TV app, enter the MAC address using your remote, and confirm.
4. Follow the on-screen instructions in the app to complete setup.

# Using the app

Once setup is complete, you'll see the main window with colorful, rounded buttons.
- Short press a button to apply the color.
- Long press a button to edit the color.

By default, the app automatically turns the LED on and off along with the TV. You can change this behavior in the settings.

## Edit preset
This screen shows the levels of each LED channel — red, green, and blue.
Adjust them to see how the LED color changes in real time.
Below, you’ll see five rounded buttons representing label colors. Choose the one that best matches the LED color you see.

## Color calibration
The app includes a per-channel calibrator to help you achieve more natural colors — closer to what you see on the screen.

Tip: By default, blue and green LEDs may appear too bright. Try slightly reducing their intensity for a more balanced look.
