Latest and greatest (Build 2.0.25-23-g9910ae2e7-DEV)
I’ll test asap. I was having trouble with losing heartbeat after about 1 second via USB.
Tested OK, using Ubuntu Gnome 17.10, Pixfalcon, didn’t test firmware update or calibration but everything else seemed good.
Heartbeat seems reliable and worked OK even after multiple reboots and APM restarts, which was probably some issue with my laptop and now updates have sorted it out.
