Sample Apps List
The Blues sample apps are purpose-built applications that address specific capabilities of the Notecard and Notehub. Smaller in scope than the Blues Accelerators, the sample apps are useful as a set of best practices and copy-and-pastable code samples to use in your connected product.
Continuous Asset Tracking with External GPS and Immediate Location Sync
This sample app aims to provide guidance for developers who are designing asset tracking functionality into their connected products. Specifically, how to build a responsive cloud-connected asset tracker that ignores power management and instead focuses on low-latency of both ascertaining GPS location values and syncing collected location data with the cloud.
Manage a Notecard Wi-Fi Network Remotely
This sample app shows how to remotely manage a Notecard's Wi-Fi connection using the Notehub API and Notehub SDKs. You'll learn how to determine a Notecard's current connection type and network, and how to queue network changes through reserved environment variables.
Putting a Host to Sleep Between Sensor Readings
This sample app demonstrates how to build projects that periodically take sensor readings, and use the Notecard to put a host MCU to sleep for a set period between readings. This approach is useful in low-power applications, where minimizing energy consumption is essential for prolonging battery life.
Routing Data from Notehub to a Custom Cloud Endpoint
This sample app demonstrates how to write a custom cloud service that accepts data from a Notehub route via a POST request, using a variety of popular backend languages and frameworks like JavaScript + Node.js, Python + Flask, and C# + ASP.NET Core.
Sending Inbound Notes and Receiving Acknowledgment
This sample app demonstrates a pattern for sending commands from the cloud to a Notecard-connected device, processing the command on the device, and then sending an acknowledgment back to the cloud. The example includes a sample web application.
Using LEDs and NeoPixels to Monitor Notecard Status
This sample app demonstrates how to integrate both monochromatic LEDs and NeoPixels in a Notecard-powered product to monitor the status of a Notecard and programmatically manage individual LEDs or NeoPixels.
