Quantex is German-based company that develops and manufactures diagnostic equipment for a variety of vehicle brands under ScanDoc brand.

Software specific to the automotive industry is a growing industry. Almost every car now offers a variety of applications and electronics to drivers which enhance their driving experience and are essential to running the car. When a fault occurs, it can be quite difficult to find out which of the many applications is responsible. That’s where the ScanDoc comes and helps to garages and car owners to identify faults in a car using the vehicle’s self-test-procedures and their troubleshooting techniques. You can find ScanDoc in cars worldwide.

“Our starting point was the need to rebrand and enhance our automotive scanner ScanDoc Compact. The enhancement should be both around functionality and the overall service portfolio that we offer our customers. The Internet of Things is essential in answering these needs,” Andrey Voronko, Quantex CEO explains on how they started the journey with Mongoose OS.

ScanDoc enables car owners and mechanics to quickly diagnose problems so that they can focus on the fix. It is not acceptable to have slow data transmission or in a worst case, a dropped connection. The diagnostic commands round trip time should not exceed a latency threshold and no significant delays or drops should be expected with the new solution. Also, the solution should support both local network and Internet modes, each with its own latency thresholds.

“We have very strict demands in terms of latency and connection stability. Our WiFi networking functionality was not reliable enough for the diagnostic applications we developed,” we heard from Quantex as the second challenge.

The answer to this challenge was using Mongoose OS with ESP8266. The WiFi module incorporated in ESP8266 provides a stable and strong connection while Mongoose OS satisfies both latency and connection requirements by fine-tuning TCP/IP stack parameters on the WiFi module.

Andrey Voronko continues: “Working with Mongoose OS was very smooth. We are not experts in implementing network functionality. They are. And they exceeded our expectations for both latency and bandwidth. The team is professional, fast to respond to questions and most importantly they made a real effort to understand our own complexities before presenting the right solution. Another vital plus for Mongoose OS, it’s open source and we are able to make changes to the project, which we couldn’t do with a closed source solution.”
