Hi.
Yes, I tried it several times, version is V1. I bought the clock some
years ago, I guess about 3, so I have no further info about the
version.
I'm a programmer by myself, so if I can get some of the specs about
what you are doing (mainly about comunication with the watch) I can
try to fix the bug.
Nice sideeffect would be learning Phyton (a bit).
Kindly regards,
Stefan

ok. thank you very much for your offer :) i would appreciate if you could provide some debugging. ok ill try to explain the communication in some short sentences.
first of all, the watches communicate with your PC by an USB-serial-adapter, which is located inside the clamb you use to attach your watch. with some really basic communication, one can retrieve data from the watch in simple ASCII-characters, which can be 'translated' into an integer[1].
to trigger the data transfer, one has to write a 'V' onto a watch of V1 or '\xC0\x04\x00\xC0' (in HEX) onto a watch of V2. (this happens in communication.py). the string which is returned by the watch has a specific length depending of how many awakemoments one have had.
this is also the cause of your bug. the length of the string has not been determined correctly, so there is a loop running behind the length of the string.
<<self.
StopIteration>>
'it' is an iterator which is iterated by 'it.next'. dat is the string containing the data. ord converts the ASCII to an integer. 'self' is the object, containing the data. the attribute 'awakemoments' is an 2D-array. the first index are the hours, the second one the minutes, which are referenced by 'awakemoments[
to begin to resolve this bug, im interested in what your terminal says. it has to respond with 'Watch uses protocol V1'. if it does not, the string is not filled anyway and cannot be used furtheron, which could cause such an error.
we are not that much into exception handling, this is something one has to do in the future, maybe by implementing some kind of easy check. dunno right now.
feel free to make some proposals. if you want to read the sourcecode and get stuck at some point, i would pe pleased to help you.
best regards,
christian.

hi, yeah actually were germans and we can communicate in our language
therefor. but i would prefer to make the public communication in this
place international.
so what i see so far, the problem is located in the line
"data = ser.read(64)"
could you try to change 64 to, say 128? you had too much data points,
they couldnt fit into 64 characters. i thought we did change that
allready. but im a little bit confused :D if you do have that much
data now, than you can try if it works. but im sure that this is the
cause of the bug here.

Hey,
I think we ran into this problem with watches running on V2 earlier on. Can you specify the line where the change has to be made please? :)

its in line 62 of communication.py. but in the current devel-branch

hi, thank you for your bug report. we are sorry that we are kind of inactive for quiet a long time now, but maybe ill have time to do some programming next month. would be great.
as long as i have other dutys, could you kindly provide the version of the watch you are using? did you try it several times to read the data from the watch?
we are far away from some kind of official release and im sorry that such basic things do not work reliably yet.
