Overview
Bluetooth® has emerged as a standard of choice for connecting local embedded applications through a smartphone or tablet. Many applications only need simple command and control, or a quick status update from a sensor. By catering to these needs, Bluetooth Low Energy (BLE) has evolved to support these low-duty cycle applications with lower power consumption. Microchip’s eXtreme Low Power PIC® Microcontrollers and RN4020 Bluetooth low energy module help in achieving low power consumption. The PIC24FJ128GB204 or PIC24FJ256GB410 devices used in this demo have an integrated hardware Crypto engine. This demonstration shows the simple communication between the RN4020 module and a Bluetooth Low Energy (BLE) supporting smartphone or tablet. The RN4020 module is controlled by the PIC24FJ128GB204 or PIC24FJ256GB410 MCU which include a hardware crypto engine used for AES encryption in the demonstration. The demo is built using standard development tools from Microchip including the Explorer 16 Board, PIC24FJ128GB204 or PIC24FJ256GB410 Processor Plug-In Module (PIM), and Bluetooth LE PICtail Plus Daughter Card. These readily available tools can be used to easily replicate this demo on your own. The demo is supported by MCU firmware and an app that will run on an Android phone or tablet. The first application is turning the LEDs on and off using the touch buttons on the tablet. The app can also show the state of the switches on the board, toggling on and off. The demo also includes data security using the crypto engine integrated on the PIC24FJ128GB204 or PIC24FJ256GB410 MCU, with up to 128-bit AES. This demo shows a PIC24 XLP MCU working with Bluetooth LE talking to an Android tablet to show basic command and control similar to what would be used for a simple IoT sensor node. This demo can also be built using the PIC24FJ256GB410 Processor Plug-In Module in place of the PIC24FJ128GB204 Processor Plug-in Module.

Package Contents
This demo is not for sale, but can easily be created from standard development tools:
- 9V Power Supply (AC002014)
- Explorer 16 Development Board (DM240001)
- Plug-In Module (PIM) with PIC24FJ128GB204 (MA240036) or PIC24FJ128GA204 (MA240037) or PIC24FJ256GB410 (MA240038)
- RN4020 Bluetooth PICtail Daughter Card (RN-4020-PICtail)
Both PIM and PICtail daughter card plug directly into the Explorer 16 Board.
The user's guide details the PIM jumper settings and other details needed to complete the hardware set-up.
The PIC24 needs to be programmed with the firmware in the zip file on this webpage in the download section.
The Android application must be installed on a compatible smartphone or tablet with Bluetooth 4.0 or newer running Android 5.0 lollipop or previous versions. The app code can be downloaded in the zip file on this webpage in the download section.
