Swiss company U-Blox has expanded its Bluetooth and wifi connectivity software with the U-Connect Script to enable easy and interactive development of embedded applications.
In addition to the established U-Connect Xpress, previously known as U-Blox connectivity software, the offering now includes U-Connect Script. The extended software series is said to differentiate the company’s offering by simplifying wireless Bluetooth and wifi device development, enabling embedded script applications in the module while reducing complexity and cutting time to market.
“We developed the U-Connect software series to let product developers focus on their main application,” said Joakim Ryden, senior product manager at U-Blox. “Pre-flashed at delivery, U-Connect manages the wireless connectivity behind the scenes. Scripting support further increases development efficiency and expands the reach of wireless technology to companies that are new to the internet of things.”
U-Connect Xpress, the first pillar of the U-Connect series for more than 15 years, has grown into an extensive software tool for integrating wifi and Bluetooth connectivity into devices. Comprising over 130 standard and U-Blox-specific AT commands, it lets developers configure device connectivity without having to write and test complex code.
U-Connect Script, the second pillar of the series, is aimed at speeding up embedded device development. It is based on the JavaScript programming language, widely adopted and with a short learning curve.
It uses simple syntax to allow device developers to embed Bluetooth applications quickly right onto the module without requiring extensive experience in embedded systems programming. Developers write their applications using U-Blox’s integrated development environment or any text editor.
Power efficient, it leverages the concept of U-Connect streams to manage data flows efficiently between wireless and physical interfaces. This ensures power consumption and performance of the resulting application to remain on par with traditionally developed embedded applications, contrary to other scripts available in the market.
Security is fundamental to all professional applications and is handled behind the scenes when using any member of the U-Connect software series. Secure boot ensures that devices only boot up in the presence of original certified software. U-Connect further ensures a high level of link and data security with support for wifi enterprise security such as EAP-TLS, IP end-to-end security such as TLS and LE secure connections for Bluetooth.
Applications developed for U-Connect Xpress or Script can be re-used across the entire product line and are forward compatible with new product generations.
U-Connect and U-Blox stand-alone modules cater to a broad range of IoT applications such as smart buildings, smart cities, smart industry, smart lighting, industrial sensor networks, asset tracking and building automation. Within these verticals, U-Connect facilitates Bluetooth-based services for cable replacement, configuration and control of equipment using handheld devices, wifi connectivity and multi-radio gateway applications.
U-Connect Xpress is available across the short-range product portfolio. U-Connect Script will be available on selected product variants, starting with the Nina-B3 module.
