Connectivity issues across halves?
I often use my Corne sitting on a bench, with each half sitting on the bench next to either side of me (often propped up in a Z tripod with magnets, but the issue I’m describing happens with or without that part of the setup). This historically hasn’t caused any issue, but today I’ve suddenly found my right half / secondary is having difficulty connecting to the primary left half while in this setup.
It definitely appears to be a signal attenuation issue, if I either bring them closer together or put them a similar distance apart without my body in between, they reconnect just fine. But it strikes me as exceedingly odd that this setup I’ve used countless times is suddenly giving me issues today.
Both are over 50% battery, and I’m connected to a host device I typically use without issue. When the right half isn’t connecting, the left half still has a fine connection to the host.
Any thoughts on what might be going on or suggestions to debug?

It sounds like you're experiencing a signal attenuation issue with your Corne wireless halves. Since you've used this setup many times before without issues, it's puzzling that it's suddenly causing problems.
Here are a few potential causes and suggestions to debug:
1. Interference from other devices: Other devices in your environment might be causing interference with your Corne's wireless signal. Try moving other devices away from your Corne or switching them off to see if it improves the connection.
2. Body interference: As you've noticed, your body might be blocking or attenuating the signal between the two halves. Try adjusting your seating position or using a different setup to minimize your body's impact on the signal.
3. Environmental changes: Have you recently introduced any new materials or objects in your workspace that could be affecting the signal? For example, a new metal desk or a nearby wireless router might be causing interference.
4. Battery health: Although both halves have over 50% battery, it's possible that one of the batteries is experiencing issues that affect the wireless signal. Try swapping the batteries between the two halves to see if the problem persists.
5. Reset bonds: Try resetting the bonds between the two halves using the steps outlined in the ZMK documentation. This might help re-establish a strong connection.
To further debug the issue, you can try the following:
* Move the halves closer together to see if the connection improves.
* Try using a different host device to rule out any issues with your typical host device.
* Check the Corne's firmware version and ensure it's up-to-date.
* If you have access to a spectrum analyzer or a tool that can detect wireless signal strength, use it to measure the signal strength between the two halves.
If none of these suggestions help, feel free to provide more details about your setup and environment, and I'll do my best to assist you further.
(I’ll try resetting bonds in a little bit, although I’m skeptical)
try using experimental connection parameters, it’s a config on the zmk bluetooth page
it should extend range a bit between the halves
