Enhanced reliability for Bluetooth Low Energy IoT products

2 mins read

Developers using Nordic’s Bluetooth LE-enabled chipsets now have access to cloud-based monitoring, debugging, and updating capabilities for enhanced development, maintenance and improvement of IoT devices.

Memfault, a provider of the first IoT reliability platform, has extended its partnership with Nordic Semiconductor to give Bluetooth Low Energy developers building on nRF52 and nRF53 Series easy access to its device reliability engineering capabilities.

The updated integration gives nRF52 and nRF53 Series developers the same experience as nRF91 Series developers with an out-of-the-box integration of the Memfault platform to accelerate product development, de-risk product launches, and ship more robust products.

"Partnering with Memfault has enabled Nordic customers to maintain and improve their devices more efficiently with deep insights into deployed devices’ performance,” said Kjetil Holstad, EVP of Product Management at Nordic Semiconductor. “Enhancing this partnership with a deeper Memfault integration into our Bluetooth Low Energy chipsets will make it easier than ever for developers to accelerate time-to-market and deliver feature-rich products at scale."

Building devices that utilise Bluetooth Low Energy introduces unique performance and debugging challenges that make access to field diagnostic data critical to delivering a successful product.

These challenges include wireless range and communication stability in real-world environments, connection handshaking and performance with varied Bluetooth LE gateways and mobile devices, and battery life optimisation.

Memfault’s IoT reliability platform helps capture relevant metrics and issue data remotely from the devices operating in development or production, develop fixes or improvements, and monitor updates across hardware and software releases.

The nRF Connect SDK v2.1.0 enables rapid creation of a data pipeline for the nRF52 and nRF53 Series to the cloud and out-of-the-box device debugging and fault analysis capabilities. It includes Memfault SDK examples and template gateway applications for both Android and iOS developers so developers can get started in minutes. With no cost for up to 100 devices, teams using Memfault and Nordic can begin using Memfault for small fleets of development devices for free.

Commenting Francois Baldassari, CEO of Memfault, said, “Pairing Memfault’s capabilities with Nordic’s products will give Bluetooth LE developers the tools and support to build better products and the visibility crucial to delivering a quality connected product that today’s consumers expect.”  

Once the Memfault SDK is deployed on the nRF52 or nRF53 Series, Memfault’s intuitive cloud portal alerts developers immediately when a bug occurs. Users can see the status of the device fleet and detailed reports with tailored diagnostic information for analysis at the time the fault occurred.

 Developers will also be able to see whether issues have the same provenance through Memfault’s fault aggregation and deduplication techniques, which show the occurrence of a specific fault across the entire population of devices.

Available data includes the frequency of occurrence, number of affected devices, and fault occurrence timeline to assist users in identifying unique issues, such as whether a specific device type or software update could have resulted in a fault and the impact of the fault. With this information, developers can easily root cause the issue and publish a fix using Memfault’s OTA update capabilities.
