-- packet ID 1100 is both PRE and ERR ?
Here what I have found regarding this:
* PRE Is issued to hubs by the host to indicate that the
next packet is low speed.
* ERR: Returned by a hub to report an error in a split
transaction. (HS Only)
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
