We’re excited to announce the most recent replace to the Golioth Firmware SDK, release 0.12.0, which now contains help for Zephyr’s newly launched Modem Subsystem. This enhancement considerably will increase the flexibleness of our platform, enabling help for a broader array of mobile modem applied sciences, beginning with Qualcomm. 0.12.0 provides help for the Quectel BG95, becoming a member of the Nordic Semiconductor nRF9160 (our go-to modem round right here!) as a first-class mobile modem. We additionally launched further methods to securely retailer credentials.
Zephyr’s New Modem Subsystem
Launched in Zephyr 3.5.0, the Modem Subsystem is a unified interface for modem drivers. This addition simplifies the combination of mobile modems (and others) into Zephyr-based initiatives, drastically increasing the vary of gadgets and applied sciences that builders can make the most of successfully. For an in depth overview of the modem subsystem, check out this summary from Zephyr’s Developer Advocate, Benjamin Cabé.
Integration in Golioth Firmware SDK
With the combination of this modem subsystem in the Golioth Firmware SDK, Golioth customers can now extra flexibly incorporate a wider array of modem applied sciences into their IoT initiatives. There are loads of nice modems and module distributors available in the market and offering alternative is on the coronary heart of what we do at Golioth.
First Supported Modem and Board
The primary modem we’re supporting with this up to date SDK is the BG95 from Quectel, primarily based on Qualcomm technology. The BG95 is paired with the nRF52840 on the RAK5010 improvement board from RAKwireless. This mix highlights the flexibleness of Qualcomm’s know-how built-in into Quectel’s {hardware}, providing builders strong instruments for deploying mobile IoT options effectively.
Why Qualcomm?
We selected to help Qualcomm modems as a result of our neighborhood requested for it! Builders have totally different design wants and need most flexibility. They want extra choices that accommodate numerous enterprise wants. Qualcomm chipsets provide the most recent in connectivity protocols and radio know-how at aggressive costs. Qualcomm gives silicon and help for a large ecosystem of module distributors, comparable to Quectel, U-Blox, Telit, and extra. Golioth prospects have used Qualcomm modems of their merchandise previously, however wanted to do a lot of the combination engineering themselves. Zephyr’s Modem Subsystem makes it simpler to develop functions that combine Qualcomm modems. Connecting this wider vary of modems to Golioth is extra hands-off for the person, decreasing complexity. Builders can focus extra on innovation and fewer on technical hurdles.
Additionally in This Launch
Along with new modem help, this launch introduces a one other function: DTLS socket offloading for Zephyr. This contains an instance for the long-supported Nordic Semiconductor nRF9160.
DTLS socket offloading leverages a modem’s safe credential retailer, which permits for the usage of safe, offloaded sockets. This implies there is no non-public key materials in RAM. This is usually a important benefit because it helps cut back RAM utilization, code measurement, CPU load, and energy consumption. Precise advantages will differ relying on the appliance and the way the code is utilized.
This new function enhances machine safety and effectivity, contributing additional to the flexibility and robustness of the Golioth Firmware SDK. Mike beforehand wrote methods to retailer credentials on the nRF9160 utilizing TLS tags.
Getting Began
To get began with the most recent SDK:
- Replace to the most recent launch, 0.12.0, from the Golioth Firmware SDK repository.
- Discover the documentation and examples offered for integrating the RAK5010 board or strive DTLS socket offloading with the nRF9160.
- Visit our community forums or help channels when you need assistance or need to talk about your initiatives.
Targeted on Your Success
At Golioth, we’re dedicated to offering you with the instruments and suppleness wanted to reach the fast-evolving world of IoT. By including help for brand new modems and enhancing the methods you may handle credentials, we intention to streamline your improvement course of and empower your modern initiatives. Whether or not you’re integrating the most recent modem know-how or implementing safe credential administration, Golioth is right here to help each step of your journey in direction of constructing smarter, extra linked options.
