android lcd module with bluetooth supplier

This HC- 08 module is a very good module for those who are used to Serial Port Profile (SPP) in addition to UART and who begin to explore more about BLE technology. BLE is less power hungry and will prolong the battery life (as it is only sending data as needed). But the drawback is that the data rate is smaller and the transmission distance is slightly reduced.

We will use this HC-08 in a simple project. In this project, we are going to update the text on a 16x2 LCD wirelessly via the HC-08 Bluetooth module, using either Android/IOS devices. The goal is to get you started easily with this BLE module without prior knowledge in BLE protocol. Once you follow through the tutorial, it will be a great kick-starter for you to explore more about the BLE protocol and creating more fun and cool projects using this module!

The characteristic and service UUID is fixed and you are not able to create your own characteristic and service UUID like those with more advanced BLE modules (i.e. Nordic based). Supported services: Central and Peripheral UUID FFE0, FFE1 (You need to know this when controlling with IOS apps)

1) Once you download the Bluetooth Terminal Apps, launch it. It will start to scan for your surrounding BLE devices. Click on connect to connect to your HC-08 Module.
