Example FreeRTOS project demonstrating SEGGER thread awareness scripts and monitor mode debugging for the Nordic nRF52840 DK

Nordic FreeRTOS SEGGER Example

This project is a copy of ble_app_hrs_freertos with the addition of monitor mode debugging and thread awareness scripts for use with SEGGER Embedded Studio.

Requirements

• Nordic nRF52840 DK
• SEGGER Embedded Studio 5.10b
• Nordic SDK 17.0.2

Installation

• Install SEGGER Embedded Studio 5.10b.
• Download the Nordic SDK 17.0.2 and uncompress it somewhere.
• Clone this project to $NORDICSDKROOT/examples/ble_peripheral.

Usage

• Open ble_app_hrs_freertos_pca10056_s140.emProject in SEGGER Embedded Studio.
• Ensure your DK is connected.
• Open the Threads window from the menu View / More Debug Windows / Threads.
• Run the project.
• Use your favorite Bluetooth utility (LightBlue, nRF Connect, etc.) from another device (iOS or Android) to connect to the running Nordic_HRM peripheral.
• Enable Notifications on the Heart Rate Service.
• Verify HRS notifications are being received.
• Set a breakpoint in a thread, for example the NRF_LOG_FLUSH() in logger_thread().
• When the breakpoint is hit, verify that your Bluetooth utility stays connected, and that you can see four threads in the Threads window: LOG, IDL, Tmr, and BLE.
• Disable the breakpoint and resume the app. Everything should continue working and HRS notifications should resume.
