CAN ERROR on a lot of commands #91

Closed elpedro31 closed 6 years ago

elpedro31 commented 6 years ago

Hi, great work on this project! Yet I'm having problems when it comes to activate smartphone replication functions in my megane III 2014 (R-Link 1), I modified my obd cable in order to theoretically be able to connect M-CAN, yet I'm having errors on almost every read command, see attached log file, so I did not try write commands logfile

I tried increasing CAN timeout to 1000ms but it didn't resolve the issue.

I'm using a bluetooth 1.5 ELM327 (probably china clone); But except for timeouts, i'm getting OK on every 95 tests on the benchmark.

Regarding version of the project i'm actually using the full master code.

Thank you in advance.

Pierre.

Don't know if it could help identifying the issue, but I'm adding a screenshot of the application. ddt_screen

Re-launch ELM benchmark and check that it's not an ARM CORE. If it is, the ELM is a fake one and won't work at all.

Thank you for your reply, I'll check this later today and let you know what I found.

No ARM CORE issue display on benchmark, plus, I tried without the custom cable and I could access to normal CAN (ON/OFF state of the car,...). I'm putting the fault on the custom cable I did. I bought a new one and I'll be able to see a bit clearer after that. Anyway thank for the tool and for the hint, where can I let you a small donation? :)

EDIT : oopsie, I just found out the paypal link at the end of the repo page!

wiring Here was my wiring (which appeared to be non working), I feel like I did a mistake between my representations of the numerotation of the pins regarding male / female, do you confirm? In my representation I'm looking at the "front" of the cable (spikes for the male, holes for the female). As an other way to tell the question : the pin numerotation (left/right) is based on the female port of the car or on the male port of the obd? I guess I know the answer but I need to be sure! Thank you a lot again for your time.

Just so anyone could not do the same error as me, my previous drawing is false, I effectively made a mistake on pin numerotation (it's the opposite on both sides), I re-made my wiring and everything worked perfectly. I'm closing the issue.
