General Discussion » Change CSV logfile Utc format in Excel » 11/06/2023 4:25 pm |
For those going from Expedition to Unix in Python:
msDate = float(vals["Utc"]) # Expedition's Microsoft DATE like 45059.344034
seconds = int((msDate - 25569) * 86400)
ts = datetime.datetime.utcfromtimestamp(seconds)

Software Releases » Tracks disappear in 11.16.4 » 7/20/2022 5:30 pm |
Upgraded to 11.16.4 on Windows and the tracks of everyone I'm following in the Pacific Cup disappeared. Messed around for a while, couldn't get tracks back.
Downgraded to 11.15.2 and they reappeared.
Bug or pilot error?
Technical Q&A » Connecting Expedition to a new B&G Zeus3 via WiFi » 6/21/2022 10:47 am |
I use a number of nav apps through Zeus/WiFi and they all work great including AIS targets. The default Zeus config is 192.168.76.1 port 10110. I use TCP, but I 'spose UDP would work, too. I've had no problem w/ Expedition/Zeus/WiFi once it was configured properly. Eliminating USB and Ethernet cables has been an experience upgrade.

Wow that did it - 2019 data is playing back with databoxes and everything. Thanks!
Google-programming (aka programming by cliche) for converting Python datetime objects:
def excel_date(date1):
temp = datetime.datetime(1899, 12, 30) # Note, not 31st Dec but 30th!
delta = date1 - temp
return float(delta.days) + (float(delta.seconds) / 86400)
Technical Q&A » logfile fields » 4/22/2022 11:55 am |
I'm trying to convert some historical logfiles to the Expedition format for further analysis - two questions:
(a) what format are the timestamps? They look like floating point numbers but aren't Unix timestamps (seconds since January 1, 1970)
(b) When reading logfiles does Expedition parse the header line to determine the set of fields ensuing or does it used a fixed set? I'm using the set from an example file, but there are many, many unused fields.
Networking Issues » Windows 10 WiFi & H5000 » 4/08/2022 9:31 am |
We fixed this with a Windows 10 generic from scratch reinstall from a pure image (not an OEM image) with no "Enhanced Microsoft Experience" or other "value added" features. This means only a local user, no OneDrive, no Office 365, no 3rd party anti-virus, etc.
- The WiFi Network Profile (under the net's properties) is "Private" and Metered connection is enabled. The profile change may be the significant one, the metered connection should prevent Windows Update and other services from firing up when at sea.
- Disabled Windows Defender Firewall on "Private" networks. Probably unnecessary.
YMMV. Caveat emptor. Illegitimi non carborundum.

We have Expedition running on a new Windows 10 Pro laptop connected via WiFi to an H5000.
We see the H5000 via the browser interface but Expedition sees no data via websockets.
Windows Firewall is disabled, Expedition is added to the network exception list, etc. I've seen that others have had similar problem but haven't found a list of what to check on any forum.
Any ideas?
