OK, here is the text of my earlier message (sent at 1702 UTC). You
should see cut-and-paste of my terminal sessions below the "++++" signs.
I'm getting strange results trying to enable GLONASS using ubxtool.
Transcript below, but in summary:
sending -e GLONASS to the F9P sends a message to enable L1, but a
following poll does not show GLONASS is still disabled.
sending -e GLONASS to the F9T sends a message to enable L1, and a
following poll shows that GLONASS L1 is enabled, but not L2.
So... is there a reason to enable only L1 and not L2, and is there a
reason why the command works on the F9T to enable L1, but not on the F9P?
Could the difference be related to my earlier question, i.e. the F9T is
using the ASYNC port via a USB converter, while the F9P is using its own
USB port?
Thanks,
John
