By providing support, service and customization -- this is the mainstream approach with Linux related products. But of course, there are a lot of bussiness approaches -- I worked for a company which sold IP for embedded products, so I'm aware of this too ;-)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
