Talking Points

Recent interactions between the hosts and their guests.

E&M Reality Emerges with Robert Fennis
Q: What advice do you have for someone importing real PCB data into eMERGE?
Keep imports simple initially, focus on essential geometry, and progressively add details like vias or enclosure features only after validating that the core design behaves as expected; too much detail early can blow up computation.
E&M Reality Emerges with Robert Fennis
Q: How important is exact material data when starting a project in eMERGE?
Material data matters, but you can start with readily available dielectric constants and loss tangents from manufacturer datasheets; refine with more precise values as you iterate, especially at higher frequencies.
E&M Reality Emerges with Robert Fennis
Q: What is the simplest way to start modeling an antenna in eMERGE for a beginner?
Begin with the simplest geometry that approximates the real antenna, model it, run a broad frequency sweep, and then iteratively adjust length to hit the target resonance while keeping changes minimal and interpretable.
Space Age Bluetooth with Alex Haro
Q: What does the hardware integration look like for developers?
The solution is open source with a Zephyr plug-in and a base C layer; in many cases you don't need to replace hardware—just install the Hubble stack via firmware updates or an SDK, preserving compatibility with existing Bluetooth functionality.
Space Age Bluetooth with Alex Haro
Q: What about coexistence with existing Bluetooth stacks on devices?
Both stacks run in parallel; you can still use the normal Bluetooth stack, and Hubble slots in when the original stack isn't actively using the channel, with timing coordination to avoid collisions.
