Apple Watch Ultra Ascent Rate Questions

[ccphares]

If it helps, here was my python script to go from UDDF to CSV. Anyone good at python would not like the way I did this, but it works. A more proper way to do this would be to use the ElementTree module, which is intended to parse XML, which is what the UDDF file is, but I didn't take the time to figure out how to use that module.

import re

uddf_file = open("c:/temp/python/uddf_to_csv/UDDF_20230710_0748.xml", "r")
csv_file = open("c:/temp/python/uddf_to_csv/UDDF_20230710_0748.csv", "x")

while True:

uddf_line = uddf_file.readline()
uddf_line.rstrip('\r\n')

depth_val = re.search("depth", uddf_line)
if depth_val: depth_val_num = re.findall(r'\d+', uddf_line)
if depth_val: csv_file.write(depth_val_num[0] + "." + depth_val_num[1] + ",")


time_val = re.search("divetime", uddf_line)
if time_val: time_val_num = re.findall(r'\d+', uddf_line)
if time_val: csv_file.write(time_val_num[0] + "." + time_val_num[1] + ",")

temp_val = re.search("temperature", uddf_line)
if temp_val: temp_val_num = re.findall(r'\d+', uddf_line)
if temp_val: csv_file.write(temp_val_num[0] + "." + temp_val_num[1] + "\n")

if not uddf_line: break;

uddf_file.close()
csv_file.close()

I have had the same problem […] It seems to be a glitch with the watch.

Sounds like an oversight by Oceanic – not filtering the real-time depth data carefully enough to avoid spurious rate spikes.

Indeed, I think that is exactly what’s going on; I had it log some ridiculous ascent rate when I waved at one point. Clearly missing some debouncing/low-pass filtering.

I really want to give AWU a try as an evey day watch + dive computer, because I don't dive as much as I used to. I don't want to spend $600-$1000 for a dedicated computer. But reviewing the Oceanic software, I am a bit under whelmed. The two main features I want is average depth on the fly calculation., and stop watch function. why we cannot get that???

If you use an Apple Watch, it's a pretty good deal. By far the best Apple Watch ever, even above the water. Wait until September to buy though- starting to look like an Apple Watch Ultra 2 is actually coming.

I agree it could be heck of a deal as a dive computer and a daily watch.. I do think the limitation is Oceanic software. I don't know why the option of having average depth isn't there, the hardware should have way more than enough capability to keep that calculation. But overall, I haven't had too many good experience with oceanic brand, mayby I cannot expect too much

Both from yesterday (I would still wait to see what happens in September). "Jaw-dropping" is just clickbait, though:

Apple Watch Ultra 2: New Leak Hints At Jaw-Dropping New Design

It’s only a matter of weeks until Apple reveals its next Apple Watch models and a new leak suggests there could be a sensational new look.
