Aaron is on vacation, so I’ll step in here… I’m sorry you did not get a response from support. I had them look for an email from you and they couldn’t find anything, so we’re not sure what happened there.
However, it turns out we don’t really need the log file that Aaron asked for. Coastal Explorer does not support the MTA sentence and has very limited support for XDR, so that is why the instrument is not showing any value.
The MTA sentence is not supported because it was deprecated a very long time ago and we’ve never actually found a device that uses them. The XDR sentence is not supported because the way that it works is different in every device that uses it (the sentence structure is a standard, but how it is used is not).
Coastal Explorer can get air temperature from the MDA sentence. This sentence has also been deprecated but is still widely used. Would it be possible to get your device to emit MDA sentences?
