Yo Gary,
many thanks for your feedback.
I'll ask again about hw it failed for you.
I don't have ttyACM1. In my case I can communicate over ttyAMA0 on
RaspberryPi with Debian to the receiver. So I run:
# ubxtool -p MON-SPAN -P 27 -v3 -f /dev/ttyAMA0
ubxtool: poll MON-SPAN
sent:
MON-SPAN (x0a:x31), len: 0x0
header: b5,62,0a,31,00,00
payload:
chksum: 3b,bb
UBX-MON-SPAN:
Poll request
#
And that's it. No more output.
I also tried "ubxtool -p MON-SPAN -P 27.12 -v3 -f /dev/ttyAMA0" but the
same.
Then I thought maybe is this device interfering with running "gpsd". So
I stopped this service but the same result.
My environment:
UBX-MON-VER:
swVersion EXT CORE 1.00 (f10c36)
hwVersion 00190000
extension ROM BASE 0x118B2060
extension FWVER=HPG 1.13
extension PROTVER=27.12
extension MOD=ZED-F9P
extension GPS;GLO;GAL;BDS
extension SBAS;QZSS
# ubxtool -V
ubxtool: Version 3.27.1~dev
# git log -1

The MON-SPAN -v 3 is designed to be easier to parse. Then you don't need
awk and friends.
awk, sed and co are my friends since more than 40 years. So it was not a
big effort for me.
Below the result of my F9P with antenna HAB-ANN-MB-00-00 for L1 and
L2 band.
Definitely is yours very similar to mine.
I realised that it depends also on the fact which GNSS are enabled or
disabled.
Kind regards
Hans
