Challenge:

An OEM specializing in data acquisition, test and measurement solutions for the automotive industry needed an efficient way to quickly upload diagnostic data obtained during performance testing from their embedded data loggers to private servers while in the field. These devices effectively measure drivetrain, engine cooling, in-vehicle climate control and A/C systems in real time.

Additionally, vehicle testers needed to access this data from their smartphones and tablets via a software-enabled access point (SoftAP) during evaluations. Having the ability to access this information in real time enables testers to determine what factors may be influencing results and whether to run additional testing, thereby reducing test cycles in new car development.

Could Lantronix provide a secure IoT-enablement solution that would allow for the seamless transmission of information from data loggers to in-vehicle testers?

Essential Requirements:

• Ethernet to Wi-Fi Bridging
• Web Manager through SoftAP
• Multicasting

Solution: The Lantronix PremierWave 2050 Enterprise Wi-Fi Module

The OEM embedded the Lantronix PremierWave^® 2050 intelligent IoT gateway inside their data loggers connected to the vehicle’s CAN bus. This compact IoT-enabling solution was ideal for the customer, who needed to maintain Ethernet to Wi-Fi bridging to connect to their remote applications. Equipped with SmartRoam, the PremierWave 2050 can automatically locate external routers and upload diagnostic data while in motion. The testers inside the vehicle could now view this information online through customizable Web APIs on their smartphone and tablet devices.

The PremierWave 2050’s production-ready software stack enabled the OEM to quickly deploy their data loggers and avoid a time-consuming development process. Furthermore, the OEM required an efficient way to reduce Internet bandwidth usage for streaming data to client groups with multiple users simultaneously. This problem was solved by the PremierWave 2050’s multicasting feature, which made it easy to manage clients by simply adding or dropping them from the grouped transmission.

Results:

• Real-time in field data acquisition and measurement helped reduce the OEM’s test cycle
• The OEM could develop their networking interface quickly
• Data could be accessed locally from remote servers
• Ethernet to Wi-Fi bridging allowed the OEM to avoid a costly redesign of their data loggers
