# iBeacon using a JDY-08 BLE module

Create and demonstrate iBeacon using JDY-08 module with HM-10 firmware.

The UUID string, major, and minor numbers are dynamically and periodically changeable during operation.



The story behind this is that I want to make an iBeacon without any high-cost Arduino shield or dedicated Arduino IDE compatible BLE (Bluetooth Low Energy) platform such as nordicRF RedBear BLEs. When I found some really inexpensive BLE module on some online shops (JDY-08 BLE module), I quickly checked the datasheet and bought some. Later, I learned that these modules can be re-flashed using HM-10 BLE firmware and then be transformed into an iBeacon. I already wrote another repo which describes the process to re-flash JDY-08 module with HM-10 firmware, here in my [GitHub page](https://handiko.github.io/JDY-08-Reflash/) or [GitHub repo](https://github.com/handiko/JDY-08-Reflash).



## Requirements

* **JDY-08 BLE module with HM-10 firmware installed** please checkout in my [GitHub page](https://handiko.github.io/JDY-08-Reflash/) or [GitHub repo](https://github.com/handiko/JDY-08-Reflash).

* **Arduino UNO** or any pin compatible board.

* **Android BLE Scanner and / or iBeacon Locator app** on your smartphone.

* **One 1k resistor and One 2k2 resistor**. Values are not extremely critical.

* **Breadboard and some jumper wires**



## Wiring

I included the fritzing wiring file in **iBeacon/Fritzing** folder (optional) if you wanna check it out.

## Demo

### Default UUID string, Major, and Minor numbers

* UUID string : 74278BDA-B644-4520-8F0C-720EAF059935

* MAJOR       : 0xFFE0

* MINOR       : 0XFFE1



### Demo - Configure the JDY-08 into an iBeacon with default values

The Arduino Sketch for this demo included in **iBeacon/Aduino-Sketches/Static_iBeacon**

Then i tried to use the iBeacon locator app to find the furthest distance i can detect it.

As it turns out, it was about 10 meters (indoor).

### Demo - Periodically change the iBeacon parameters (UUID, Major, Minor, and Advertising interval)

The Arduino Sketch for this demo included in **iBeacon/Aduino-Sketches/Dinamic_iBeacon**.

Here you see the serial monitor output when it was a one-time-only configuration (left) and periodic configuration (right)

While it was running, you can comfirm the parameter changes with the BLE scanner or iBeacon locator app
