SRF OBD connector
« on: March 10, 2020, 03:29:07 AM »

Does anybody know if the SRF has the possibility of connecting a bluetooth OBD2 adapter?
something like that:
https://www.amazon.com/OBDLink-Bluetooth-Professional-Grade-Diagnostic-Performance/dp/B07JFRFJG6?ref_=ast_sto_dp

In order to obtain similar data as this guy is getting from his Tesla:


with an app similar to that one:
https://play.google.com/store/apps/details?id=com.emon.canbus.tesla

That would be so cool to be able to extract more data from the bike!

So, the OBD-II port on a Zero is functional, but your standard automotive connector dongles will not work with it.

One main reason is that a lot of the pinouts are different, but a big issue is that there is no power to draw from to power a Bluetooth antenna on it, so whatever data logging or interactive programming you do must have its own power supply. The 12V off the DC-DC converter should be sufficient, but keep some circuit protection in there to avoid an issue.

Anyway, there's an extensive article on MBB console access using this port:

There's also CANBus access, but decoding CANBus messages requires more development time, and no one's proved it out yet on an SR/F or SR/S.

This is no longer true for 2020 models. For EU regulations, they had to add an OBD compliant port that works with standard readers. There are now two OBD ports on 2020 non FST bikes. It also has 12V supplied where you expect it. The FST platform bikes have one port but it works just fine with readers :)

Prove it! Forum posts are cheap. Let’s see some evidence.

I have an SRF and a cheap bluetooth dongle... The port is in the tank. just never tried it because my daily phone is an iPhone. I'll try this evening if I can connect with it using an Android phone.

That would be nice if it worked!!
I'd like to have some sort of an additional data on my dashboard (even if I had to buy a cheap android phone for it), indicating things like the battery charge, temperature, regen levels, instant power ect…
That would be a geek's dream ;)

The official app and the Metrics For Zero Motorcycles app can get you all of that data.

No, it cannot get you "all of that data". I work with MBB logs, the MBB console, CANBus data, and the metrics app, and they are much deeper when parsed correctly.

Plus, the official app and metrics app only deal with numbers, not logical conditions and events for diagnostics.

I was talking about the data that Larry is after. Battery charge (SoC and voltage), temperature (motor, battery, and controller), regen amount, power output.

Metrics For Zero Motorcycles app doesn't work for the SR/F and SR/S right?

I am looking for data as per those in the video, and presented in the form of a dashboard with live updating as I ride around.
I don't think the Zero app would do that? Would it?

for SRF that information can only be retrieved by recording a single trip and then watching it back afterwards. So no live data, and you have to start and stop recording manually within the app.

The official app gives you some data. It might be different with the SR/F but for my DS you go to the settings tab (can be in demo mode if you don't want to connect to your bike right now), ride screen setup, then tap on one of the numbered panels to bring up a list of all the info you can choose to display there. You can then click on ride screen preview to see what it will look like, and if you're connected to your bike it will then show live data. I do believe that if you have the app open and connected it will also go to the ride screen automatically when you start moving.

No one has confirmed a test of that app against the Gen3 motorcycles. I would presume that it doesn't work because the bluetooth data protocol is different, but it's possibly backwards-compatible.

Let's be clear, here:

Zero's official app for Gen3 bikes doesn't accomplish what the OP asked for, and any solutions for Gen2 bikes are reasonably presumable not to work for Gen3.

The one caveat to this is the open source app developed to use the Gen3 cloud service, which focuses on a narrow amount of data, although it does log GPS coordinates. (Note that the GPS coordinates seem to be local on the bike to the cellular data unit, and are not logged by the MBB or emitted to the official app.)
