OBD-II Cables
by Mark Webb-Johnson 11 Aug '13

I'm going to order another batch of OBD-II cables (changing factory because the one I used the last few times is so unresponsive). Is the current 1metre cable length good, or should I order them longer? Regards, Mark.

Re: [Ovmsdev] OVMS VIN 4E9->4F1->4E1 (was OVMS VIN 4E9->4F1)
by Mark Webb-Johnson 07 Aug '13

Michael, OK. I found some old logs you sent me before and these show: 7.628 R11 4E9 E1 80 00 04 6C 00 7.637 R11 514 47 31 52 39 36 45 34 39 8.647 R11 4F1 41 A1 01 A1 00 36 08 88 The 514 looks fine. But, both 4E9 and 4F1 look wrong. In particular, the 4F1 has '41 A1 01 A1 00' - which is what we are seeing for your VIN. But, id #4E1 has: 8.694 R11 4E1 43 55 31 31 36 34 38 39 If the VIN was in 4E1 and 514, that would give us: 8.694 R11 4E1 43 55 31 31 36 34 38 39 7.637 R11 514 47 31 52 39 36 45 34 39 Or, CU116489G1R96E49 for your car. For RScott, his logs show: 41966.094 R11 4E1 42 55 31 30 32 36 38 39 41966.110 R11 514 47 31 52 44 36 45 34 36 Or, BU102389G1RD6E36 for his car. Is that correct? Reading back through the old eMails, I find this from RScott: > The VIN can be constructed by taking the number "1" and converting the CAN IDs 4E9 and 514 to ASCII. So with "4E1 4255313032363839" and "514 4731524436453436", you would end up with 42 55 31 30 32 36 38 39 47 31 52 44 36 45 34 36, where 42 is ASCII for B, 55 is U, etc. So, I think the whole 4E9 was just a typo, as 4E1 is what is mentioned later in the same sentence. I've committed the code with 4E1 into github now. It works ok on my simulator, and hopefully should be ok in your car now. Can you try? Regards, Mark.

Not sure why they would not show up in the App. Perhaps the corrupt VIN# is messing up interpretation of that message?

Two changes to the server code
by Mark Webb-Johnson 05 Aug '13

05 Aug '13

Just made two changes to the server code: The first time a vehicle fails to authenticate (wrong server password), the Apps for that vehicle will now be sent a push notification telling them about the problem (along with the IP address of the vehicle). If the vehicle subsequently managed to authenticate correctly, the apps will get another notification telling them that. Hopefully this will help with setup in cases where the server password is incorrect. I've added a second method to submit vehicle history - the 'h' message. This is the same as 'H', but is prefixed with two extra fields - an acknowledgement ID and a time difference (in seconds). When the server receives an 'h' message, it replies with an 'h' message of its own, containing just the acknowledgement ID. The time difference is used to move the historical data timestamp back the given number of seconds. This allows the vehicles to send in historical data delayed by N seconds (for example, if the link is down and they can't immediately submit). It also allows the vehicles to get back an acknowledgement that the data has actually been recorded successfully. The new server code is already live. I'll commit to github with the ACC stuff I'm currently finalising, as soon as a I can (but maybe a few more days until its ready). Regards, Mark.

Ampera/Volt unlocking
by Nikki Gordon-Bloomfield 05 Aug '13

05 Aug '13

Did we ever discover the message for this? The reason why I ask is that I managed to lock myself out of my wife's Volt on Saturday when running some shopping errands. I got back to the car with a couple of bags of groceries, opened up the boot, and put them inside. Along with my keys…. then the Volt wouldn't let me back in. On my LEAF, it's impossible to shut the keys in the car, because the sensor detects there's a key in there and beeps madly at you. The Volt apparently has a dead zone just in the rear of the hatch area. In the U.S. OnStar can certainly unlock your Volt remotely, so I'm sure the codes have to be there… it's just a matter of finding them. Thoughts? Nikki.

Problems with Ampera setup…
by Nikki Gordon-Bloomfield 05 Aug '13

05 Aug '13

Hi folks, I'm helping an Ampera owner connect his OVMS for the first time using global sim. We confirmed that we could get data working on an iPhone 2g before putting it in OVMS module, but while we can get everything via SMS, there's no luck with IP. GPRS? gives two different errors now. First time it was Not Connected (0x0024) The second time, it was 0x0023. Any ideas? Nikki.

ODO issue once again
by Kevin Sharpe ZCW 30 Jul '13

30 Jul '13

On the 2nd July OVMS stopped reporting my Tesla ODO… I had this problem historically but it just started working one day and had been fine until the 2nd. I've tried power cycling the unit but that did not help. I was driving in mainland europe at the time and could not receive text messages from the unit although the data connection was fine. Any suggestions?

Volt issues.
by Nikki Gordon-Bloomfield 28 Jul '13

28 Jul '13

Hey folks, Finally got the Volt today -- a replacement for our Twizy -- and so got to putting OVMS in the car. The first thing we did was ref lash the module with the latest 2.3.2 firmware. Then checked that it was set to VA in vehicle type. Logging into OVMS and texting the module gets a response. I'm even picking up the VIN number from the car.. But what I'm not getting is the battery SOC, nor does the parking timer appear to be correct. Thoughts? I've got quite a few Ampera/Volt folks in the UK who would like to install, and I said I'd go first. Nikki.

Development of C-Zero/iOn/iMiev version
by Matt Beard OVMS 25 Jul '13

25 Jul '13

Hi, I am now the proud owner of a V2 box, and accessories for ODB-II connection etc. Unfortunately I currently don't have an EV... but as soon as my C-Zero returns I intend to fit the OVMS. Is there currently a draft iMiev version of firmware? I have seen some partly decoded CAN details. I suspect I will also need to start CAN-logging. Matt Beard
