Error 22 Incompatible Hardware Detected
-
@mike Your present Jw chip needs to be relashed to pair a 4209 bms to your 4212 controller. Owie 1.3.0 is the firmware that is flashed on a esp 8266 chip and will pair the 4212 controller to a 4209 bms.
Since the Owie project is public and free, in my opinion, charging a fee for programming the chip isn't right, but that's just my view.
I think whatever you do, keep in your comfort zone, but we're here to help. -

utopian nonsense. time has value. charging for it is reasonable.
-
@notsure Yes, time is valuable, the time spent by the Owie project developer was also valuable, but was given freely. In my personal view, the firmware was free and should be forwarded.
I would rather mentor someone with what I learned, either by mistakes or successes rather than doing for them. -

but the two acts scale differently. i can compile a piece of software once n deploy it infinitely. flashing roms occurs once at a time not including the "loss" incurred in deployment. most of the underlying infrastructure of the internet is in fact open source, but web devs still get paid. network admins get paid. the guys that install the hardware get paid. open source slicers for cad/cam... u pie-eyed dreamer u lol.
-
@notsure Haha, that's how I make my projects come to life, from dreams and dreaming .
I'm pretty sure others in this group especially Lia fallows a similar path. -
how hard is it to flash this thing? looks like the instructions are here below. i'm a developer so there's no excuse. i should just do it for mike.
https://github.com/lolwheel/Owiealso for mine and mike's references:

flashing was a pain and not working until i realized i had a bad usb cable lol. then it flashed beautifully. got it all nicely soldered in (was weird that the green wire from the connector was to be left disconnected for this install!). and it works! though he's only getting stock range (it's a jwxr battery), so seems Mike needs to do some more homework. oh and this is with a new (used) BMS.
-
ugh so range was good for a little while, but then he started getting battery temp out of range. had to walk 3 miles to get back to his car with his brick ow cause it wouldnt cycle back on. also, as you can see in the screenshot, the diagnostics page is missing a LOT of entries.
he filed an issue with owie, but it got closed, crossposting here
https://github.com/lolwheel/Owie/issues/57"OK you def have hardware issues.
- BMS is reporting over/undertemp - the status message has bit number 1 set on it.
- One of the temp sensors seems to be busted/disconnected as it's reporting 0. I don't know which one is which.
- Your cells seem to be super out of balance.
I'd suggest opening up the battery enclosure and wiggling the balance lead.
This ain't Owie issue, closing."
@Lia do you know where the battery temp sensors are? is this on the battery or the BMS?
seems like this is just another poorly made jw battery ?
-
@swinefeaster Pretty sure they're just on the battery. 4 of them on the XR. @radimklaska has a great page going over the pinout and types. t1-t4 are the thermistors.
https://klaska.net/onewheel/bms/
I would imagine 1 of 4 issues has happened.
- Pin on the connector for one of the 8 connections has come loose.
- Wire has kinked and broken internally.
- Thermistor has outright broken.
- Trace on the BMS has broken.
Considering the state of the crimping on that pic you shared in the E16 thread where some wires had come loose I would imagine that is what has happened.

@lia thanks for the info! this is a different battery though.
