Hi Markwj, I do not know how to easily check the GSM signal. Is that status indicated on the VDS Stats?
I can't remember exactly where, and don't have access to the car at the moment, but definitely remember the GSM status and signal being shown on one of those DIAG screens.
Okay, I searched around and found on the "FW Versions" screen, the last three lines down at the bottom of the report may be related. I see a value for ICCID, IMEI, and the last line (in red text) is "Offline" sometimes followed by "2dbm".
I wonder how hard it would be to upgrade the car to turn that back on.
Yep. That's it. "Offline" pretty much sums it up.
Not going to happen, IMHO. They would need to change the modem module to a 3G/4G version. Nobody is going to do that for a discontinued model like the roadster (especially when the manufacturer is paying for the data, not the customer).
How about a low power (in garage) DIY 2G base station setup to let the car use the legacy technology it has, patched to home internet access? Seems possible.
Build Your Own GSM Base Station For Fun And Profit
Why not try the new OVMS3 that Markwj has been working on for a long time?
You are in an area that should have GSM coverage and then you could check your Roadster
similar to the way you are able to check your Model S with the Tesla app.
For $150 or $160 it is a real bargain...
I got mine a month ago and I really like it...
Markwj is working on a new harness to allow us access to the CAN bus.
Thanks for that suggestion.Hi driver_EV,
Warning: You might need to check with @markwj to see about the level of your
OVMS3 and the harness for it.
The time you ordered was about the time Mark added some internal wiring for the
K-line support. There is also a new harness necessary for the K-line support.
It is labeled OVT1 and it has all of the wires for the K-line and the multiple CAN buses.
It will be better to get it all together, rather than a few back and forth orders to China...
When you receive and install the OVMS3 harness and the K-line kit,
I will be happy to help if you need it with the K-line and TPMS implementation...
I am well suited for the TPMS but @markwj is the expert for the OVMS3.
As a preparation step for the K-line add on module and activation of the system,
It would be beneficial if you could get the addresses and locations for the TPMS
sensors on your car now... You will be ready when the equipment arrives.
