BLE5-Stack Long Range Peripheral

Functional Overview

This example page will demonstrate the Bluetooth™ 5 Long Range capabilities of the Texas Instruments CC2640R2 SDK's BLE5-Stack.

This project is a modified Simple Peripheral sample application from the BLE5-Stack component of the SDK.

This list contains the changes from the standard Simple Peripheral example:

  • Removed the Simple GATT Profile
  • Added Support for a custom profile called Throughput Profile
  • Added Support for a custom profile called Temperature Profile

The Long Range Peripheral is intended to be a head-less device that can used with a USB-powered battery pack to evaluate range capabilities. All the control functions are handled by the Long Range Central device. Once connected, the Central instructs the Peripheral to negotiate the use of the Coded PHY at which the device will update the LED status and start gather temperature data. Similarly, when the Central enables notifications on the Temperature Profile's Data Characteristic, the peripheral will send the temperature data to the central at a 1s interval. Once the connection is dropped or terminated, the peripheral must be moved within the range of a 1M PHY.

Project Hardware

  • 1 CC2650R2 Launchpad

LED Output

  • RED: Solid RED indicates the device is not connected to a central.
  • GREEN: Blinking GREEN indicates the device is connected to a central in using the Long Range Coded PHY (S8).

Two Button Menu

The Two Button Menu system is designed to utilize the two push buttons available on the CC2640R2 Launchpad. The left button (BTN1) is always used to cycle between options. The right button (BTN2) is used to activate the selected action or item.

The Two Button Menu is set up by default to utilize the back channel UART present on the Launchpad as it's display.
