I've often had an "aaah #$%^" moment in the shower, during a "bio break" or while driving. If I get stuck for more than an hour then I go home and will often figure the problem out.
One strategy that seems silly, but often really works, is to have a whiteboard in a room with a teddy-bear in a chair. If you get stuck then go explain to teddy how it works. In doing so you'll often find the problem.
Good..normally the biggest problems are solved when you change the envionment, i guess if we keep working in the same place and keep seeing the problem we tend to ignore minor problems that are actually the cause.
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.
