Bluetooth TV

This project uses the MOTG Bluetooth by 4D Systems. The MOTG acts as data pipe which allows a smartphone app to control the current video playing on the display. This project uses the DATA mode of the MOTG which allows communication between the Bluetooth Module and another Bluetooth Device such as a smart phone.

How it Works

Components

• MOTG Bluetooth

• gen4-MOTG - AC1

• gen4 - uLCD 70DT

• 2 pcs 30-way FFC Cable

• gen4-PA

• Smart Phone Smart Discover App

• uSD Card

Implementation

Step1: Build

• Connect the components as shown in this diagram

Step2: Program

Download the project file here. The image below shows the programs to load to the LCD. Click the 4D Visi Project to open or edit the project.

Step3: Compile

Click on the “Compile” button on both projects,

Note: This step could be skipped. However, compiling is essential for debugging purposes.

Step 4: Comp’n Load

Connect the display to the PC using uUSB-PA5 and a mini USB cable. Make sure that you are connected to the right port. Red Button indicates that the device is not connected, Blue Button indicates that the device is connected to the right port.

Now click on the “Comp’nLoad” button.

Workshop 4 will prompt you to select a drive to copy the image files to a uSD Card. After selecting the correct drive, click OK.

Step 5: Mount uSD Card

The module will prompt you to insert the uSD card.

Properly unmount the uSD card from the PC and insert it to the uSD card slot of the display module.
