Is it question of time compression - using ext IP produces the assumption that NO work will now be needed on that function? Reality is that time is needed to characterise the new IP, at least to run it safely in a test harness wherein future suspected bugs can be verified / hunted down. Using own IP is often out of the question due to complexity anyway.
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.
