Hey All,
Im a little confused with my unity and FW5.
Setup everything using the can forward feature (new to me but ok)
I basically have to treat the unity like two can connected escs, sure no problem.
But now my unity wont work, and neither will my telemetry on my remote.
Usind metr pro unity and feather remote with unity fw.
metr turns on and connects, but no data gets through.
Feather can gas it but gets no telemetry.
Reverting to unity fw worked and telemetry came back.
Settings and clicking on the blue gear near the module name.
Click Upgrade and wait until firmware update over BLE is complete.
I’ll try that tomorrow and get back to you.
I assumed it was vesc related since the feather is out too
The old unity firmware had a slightly modified packet structure. Because of this many Arduino style remotes have modified library due old unity firmware.
My guess would be you more need to update your remote firmware and set it up using standard vesc library rather than unity library.
@Deodand thanks for the super responsive changes. If vedder is ok with it then i look forward to another beta firmware to test.
Damm, the speed of implementation 
I’ll try it out too when available!
has some wierd behaviour today, dont know if its FW5 related but its not something iv not experienced before.
Basicaly when going up a long hill i started to notice a weird “pulsing” feeling with the power. here is the log section https://metr.at/r/L17ox?zoom_start=6320&zoom_end=6600
so at the point i marked with blue i started to feel the power drop away, you can see that the motor and battery current start to drop off even tho the PPM is stable. Shortly after you start to see the motor and battery current start to oscillate sharply, again whilst ppm is smooth. At the yellow mark i notice the weird feeling and let off the power.
Interestingly at around the same time the motor temperature seems to get really noisy. all recorded values are below the motor thermal limits but im wondering if there extra samples between the graph data points that were not logged. Its starting to get warmer here so it could well be a combination of warmer motors and noisy temp sensors but why did they get so noisy all of a sudden at the same time i started to loose power?
any ideas? any way to smooth the temp sampling?
Nice (or not) to see someone on the same situation
I have this happen since forever, when near the temperature limits and at high phase currents, they induce noise in the temperature measurements and the current limiting kick in and out all the time, depending on how noisy it gets really dangerous
There should now be some heavier filtering on the motor temperatures. Which ESC and which Beta version of FW?
Unity and I think I’m on beta 3 or 4 but I will check tomorrow. Also looks like I can only see 1 motor temp sensor on the logs although this could be a hardware issue or an issue with metr logging. Again, I will hook up the vesc tool tomorrow and see if I can read both temp sensors from there.
Yeah Beta 5 or 6 has increased motor temp filtering. So make sure to run latest. Let me know which Beta version you were on when you update please.
Having the high impedance temp sensor run parallel to phase leads can cause some interesting coupling so heavy filtering is needed I think.
Would wrapping the sensor wire around the phase lead run help?
Wrapping metal foil/mesh around the temperature wire and connecting the foil (or wire mesh) to ground can definitely help.
Or just using a very small coaxial cable all the way from inside the motor to the ESC could help, with the shield connected to the Sensors or PWM (“PPM”) ground pin.
Hmmmm I hadn’t thought of that, faak me… I have copper shielding foil that we sometimes use on noisy quads… one of my boards is about to get a refirb. I’ll wait and see what @Deodand has to say about the matter, and maybe wrap, and twist the sensor wire around the phase wires…
where do i find a “ground” on an electric skateboard?
ESC ground
battery ground?
the gnd pin in the sensor harness? (i assume this is tied to the mcu gnd pin)
Yes, either that or the ground pin in the servo header or the ground pin in the SWD header or the ground pin in the CANBUS header. Definitely NOT battery negative and NOT the big fat black wire powering the ESC.
Im on 5.4 now for metr,
the april 22 version of fw5 and still no luck…
My remote however, does work. @ducktaperules thanks for the tip
For some reason my motor temp shows as -99.9C
I’ll look into this.
