Have a new RTK Facet mosaic L-Band that appears to be in a boot loop. I did some initial setup and got my phone paired, and went out with SW maps and recorded some points, and experimented with RTK corrections via the phone.
I was attempting to put the facet into config mode so i could connect via wifi to go through the config menus. The facet would not go into config mode. When i stopped the menu on ‘config’ after about 8 seconds, it returns to the main screen.
On boot, i get the normal boot sequence, and then the unit displays:
base started
survey started
and after a few seconds it reboots.
When the device powers up/boots, no serial port is getting presented to my PC. Also when plugged into USB, the green led for charging does not come on.
I did have a serial console (via usb hooked up when it happened, and this is the capture from that).
