Story

This project is to add iBeacon functionality to Wio terminal, The purpose is to advertising Wio's information via iBeacon, and then use a smartphone scan the Wio terminal and read the information.

It just a simple advertising function though, However, we can already see the Wio connection signal strength, delay, UUID, and other information through the iBeacon function. What can be done on Wio is limited for the time being, but I will try to develop more applications in the further.

Feature

Wio terminal can be advertising the information via the Ibeacon function.
it can notice the signal strength of the connection, delay, UUID, and other information.

Get Started

materials required

seeed Wio terminal

Software Required

Arduino IDE Download
You need to download the nRF connect APP on your phone

Wio terminal Firmware

Before you upload the code, you need to download the library to support the code. please check here.

Install the LCD screen Library Seeed_Arduino_LCD, please visit Wio Terminal LCDfor more information.

install the FreeRTOS Library, please visitthis GitHubdownload it.

Install the BLE Library Seeed_Arduino_rpcBLE, please visit the Wio terminal Bluetooth.

Instructions

step 1. upload the code on the Wio terminal.

Step2. Open the nRF connect APP to search the Wio terminal device.

Step3. You will see this icon, then click it, the information will be repented.
