Hi RUSP family,

I'm running into a third issue. On the main branch of firmware, it doesn't seem like I can answer the line when a phone call is incoming. However, when I flash the statusline branch, it seems to work fine.

This is the repository I'm working with.

https://github.com/skysedge/rusp_firmware

Here is a video of me trying to answer a call with the main branch and how I'm flashing the firmware. I then flash with the statusline branch and show that I can answer the call. The speaker is disconnected in the video, but that seems to work fine on the statusline firmware.

Any thoughts? Are there other forks of the firmware that folks are working on that you can share?

Thanks,
eppy

I threw in some debugging in the firmware and can confirm that the hook button is working at least.

Which produced the following.

It's interesting, for a moment, it did produce the "hall" output as well. But, I'm not sure what I did. I was tightening the daughterboard screw that holds the mallet in place when it showed and blinked a bunch of lights at the same time. What is the hall sensor for?
