Hi. nice program and just in time. I received my obdII BT dongle from dealextreme and tried it out with my n900 and pyobd.
Up till now I had little luck in connecting with my BT device.
after pairing the device, clicking "connect to ECU" and waiting for 30 seconds or so, I get the message "Error can't connect".
the last lines in the terminal output of pyobd (version 0.9.2-11) say:
...
Send: ate0
ate0
Send: 0100
NO DATA
Send: atz
ELM327 v1.4
1
Send: ate0
ate0
Send: 0100
NO DATA
send atz
Send: atz
does anybody have an idea what is wrong?
Thanks in advance,
Farid

Maybe your ECU, under the command "0100" respond differently from what is expected by pyobd or your Dongle is a bit "slow".
Have you the possibility to connect via PC to your BT dongle?
Just do the BT pairing from the PC and then use a terminal (hyperterminal for winzoz).
The commands to give are:
atz
ate0
0100
Then post all the result.

Hi,
I just noticed that oxygen sensor(0114-011B) voltage values are not calculated correctly. Their range should be -100 to 99.2% or 0-1.275V. Now they are showing values like 5000.
http://en.wikipedia.org/wiki/OBD-II_PIDs has formulas for calculating value.
Currently they are calculated with formula (A-128) * 100/128.
I think the formula for showing value in Volts is: A/200
Formula for showing percentage is (B-128) * 100/128 (if B==0xFF, sensor is not used in trim calc)

Thank's Wictor.
I have not changed the original formula present in pyOBD.
Surely i will try to correct the formula in the next release, but for now i will wait other feedback on the functionality.

Hi m750,
in your first post you wrote:
"
Remember:
1) wxPython libreries are needed (20MByte)
2) I added several OBD codes, but this application, as the original, has several limitations.
3) Please, remember thath pyobd is under GNU License"
Where can I find wxPython libreries?
Thanks in advance?

I will compare the readings with another scanner this weekend.
Is it possible to include a feature that will when selected write to a file the current OBD values? It would make comparisons easier & be a useful thing to have anyway.

@miroslav_s: in the maemo repositories. wxPyhon libreries where automatically installed with pyOBD for maemo.
@rotoflex: it is a good idea. In a new release i will try to create a symple log file.

I have issues with pyobd too.
in terminal i can issue:
atz
ate0
0100
and get proper responses, but i get ERROR replys in pyobd.
My device (ELM327) came only today, but from the test i have done so far, carman works OK. (it seems to also open up rfcomm line).

I kindly ask you to provide RATEs (Package Karma) necessary to pass this new version (0.9.2-11) from extras-testing to extras-free.
