Bafang GO+ parameters change

[stancecoke]

To be aware though that the Go+ App will only set what is available to be set in your region hence the need to set up an account and log in.

Interesting information about geofencing. Are there screenshots of menues that are only available in countries with weak rules for E-Bikes? It should work to connect the mobile phone via VPN to a foreign provider to get access?
We would have to decode the meaning of each of the 256 bytes in the payload of the CAN messages, then we could send the "right" bytes ourselves by any suitable CAN device.
The documented commands and payloads are far from complete as far as I found in my first CAN sniffing attempts.

 

[Waynemarlow]

I think the developers called Casainho and also Cidi who frequents here has most of the CAN messages ?

 

[Waynemarlow]

Most use New Zealand as their VPN home country

Might be worthwhile purchasing one of the M510 or preferably M560 FC2.0 or FC2.1 controllers from Aliexpress to learn what CAN messages Bafang send to the display and then BTE over to the App.

I may have a damaged FC2.0 controller that still talks to the display if you PM me your address ?

I'm working with the hubmotor controller from windmeile.de, I guess they are all using the same CAN protocol, as they are all working with the BESST tool....

Thank you for the spoiler "can sniff" in post 20. Now i could compare parameter 6011 with my controllers. Specific bit 3 - 4 and 5 - 6 from parameter 6011. Your controller seems to use bit 3 AND 4 too for calculating the undervoltage which seems to give for your controller 31 volt. BESST (if it can show parameters 6011 and 6012) will probably show a wrong value in this case ( at least my version 1.2.43.0 does) because it uses only bit 3 to show undervoltage value. So does OpenBafangTool.

A controller of mine, CR S10F.350.FC uses bit 3 and 4 too for calculating undervoltage which is 38V (43V system) and BESST shows 216V ! Because BESST reads only bit 3 and not 3 and 4 together. However a similar controller but with older HW and Softw, this one uses only bit 3 for undervoltage and also only bit 5 for recovery voltage and on this one BESST shows the correct value's. But not for controllers which are using bit 3 AND 4 for undervoltage and bit 5 AND 6 for recovery voltage. So that had me confused for a long time but your controller uses bit 3 and 4 and 5 and 6 too so i'm satisfied now lol.

So it looks like BESST and OpenBafangTool will show wrong value's for some controllers regarding undervoltage and recovery voltage. Possible Bafang changed some things over time regarding those value's who knows.

I saw in your table most data for parameter 6012 is zero? Is it a controller with torque settings?

I found something interesting on github to check out too but i don't know anything about it and why it is that it seems nowhere mentioned. So i don't know what to think of it.

very interesting. I've just downloaded and unpacked the repo. It's a HTML gui and runs without compiling, just double click on the unzipped HTML file. But it doesn't connect to my Canable module. Maybe because I bought the cheapest (old) one.
With the Cangaroo tool it works....

Hm, there seems to be a write command with one byte 0x40 payload, that announces a "long write command" for the 0x60xx parameters. It seems, that I have to learn a lot about this protcol
The 256 bytes payload are described here, even the torquesensor settings can be found there

Trying to connect to BESST and the same message comes up " Disconnected Websocket closed " any clues to get it to run ?

 

[stancecoke]

Hm, I found, that the app doesn't send the settings to the controller. If you change to the main screen and go back to the settings, the old values are shown again.
So I have to try an older version, or proceed with the BESST tool

D you mean from the github link i posted? In server.js i saw a VID and PID mentioned and my (2) canable's have different VID and PID. I also saw in those files mentioning candlelight so i thought maybe my canable needs Candlelight firmware.
I flashed online candlelight firmware and now the VID and PID are the same as the ones in server.js from the github link. But stil not working.

In the end i have put a bootable UBUNTU image on a external SSD. I'm not a programmer at all and i don't know anything about Linux. But long story short ( 1 full day trying as compleet noob) my canable with now candlelight firmware works in UBUNTU. Replay canbus logs (canable SLCAN serial) on windows laptop and receiving it on another laptop in UBUNTU via my second canable with candlelight firmware. So my canable with candlelight firmware works but still no go with the github repository link.

You can start index.html but that's just it, it runs till the end of main.js in the map UI. Nothing shows up in the index.html because the server.js is not running. Or it checks for the canable device and something is not right and stops?

package.json points to server.js as the "main". I think something needs still to be done so that server.js automatically starts ands feeds data to the index.html. I tried to manually start server.js but got error "ws" package not found. It has some dependencies and "ws" looks like one of them. See also package-lock.json but actually it's all latin to me.

Again i don't know anything about programming, but here in this forum i guess some people are able to figure out what needs to be done to get it running. Under windows probably no luck as long as candlelight firmware is not recognized?
Sorry for the long post but i hope someone will take a look at it. BTW on github, issues 1, that is me I hope the developer did not leave this project as it looks promising.

I have read that canable candlelight firmware does not work under Windows anymore? When flashed with candlelight => Unknown device, no drivers for the 2 instances, don't try zadig, i did.

One thing for sure, you know a lot more about programming than I do. AudreyPR uses the BESST tool from Bafang to link his CAN program, perhaps have a look at his code and see how he handles the interface to Windows ?

 

[stancecoke]

In the Telegram group there was this hint, thanks to @Tomblarom!

stancecoke it turns out, the index.html is expecting a backend server running on localhost:8080. You need to install NodeJS and run:

npm //test NodeJS install
npm install
node server.js

 

[DPC18RI]

Yes thanks to Tomblarom server is running on my end too now under windows, but i get no data for now by replaying a can log via other laptop. Will check this afternoon connected to a motor. Here is the answer / solution.

I've forked the repo, updated the ReadMe and added two batch files to make it easier to install NPM and start the server.
The pull request is done.

Not for me, see my new comment on github.

I've added the hint for the needed processor and firmware to the ReadMe

needs STM32F072 processor with candlelight firmware

with the latest candlelight firmware, there is no need to install additional drivers, windows recognizes the module automatically:

The Firmware also implements WCID USB descriptors and thus can be used on recent Windows versions without installing a driver.

Sadly, if you are searching for "Canable" at eBay or aliExpress, you don't get that detailed information about the processor and the firmware
I was lucky to buy a "right" one (FYSETC UCAN) by coincident.

The author of the tool is a member here at ES. But he wasn't seen for quite a long time now.
Nevertheless: big thanks!!!

@Stancoke, thanks for bringing that GitHub project up to a working conclusion.

Now all we need is someone to write the code to allow the BESST tool to be useable with this CAN tool for us code dummies, there are a lot of BESST tools out there as it offers plug and play ( give me engineering problems, coding is just not my forte, sorry ).

AudreyPR's is nearly there, but I think its missing part of the setup, that of the torque sensors Delta Voltage

This thread goes into it very well.

Ultra Tuning: Decoding the Voltage Section of Torque Tab

EDIT: This revised post corrects and updates previous information. Thanks to @ProphetZarquon for his insights! EDIT #2: See post #10 below for a How-To primer in case you don't want/need to understand but to try this out. Everyone should update their Base Voltage at least! I've undertaken yet...

forums.electricbikereview.com

I'm not sure how Audrey uses this initial calculation of the spread of the sensor voltage and I'm not sure how Bafang do it but I suspect that only part of the torque sensors out put is being used ( probably simply read from 0 volts ) on the M820 engine that I have ( in comparison to the M510 motor the sensor is very much on or off although with the testing and alteration of the SPD parameters I can dial this in a bit better ) .

If we had this part we could at least make some assumptions then become predictable and also make the torque curve more tuneable.

But perhaps the M820 does things in a slightly different manner to the Bafang Ultra engine as I suspect the Spd tables that I'm using in the OpenBafangTool has slightly a different effect than the thread below. Is it the way Audrey calculates the Delta voltage or is he simply reading the output values from the motor and then integrating them in the Spd table ?

Ultra Tuning: Decoding the Torque Tab's SPD Table

This will be 2 Posts: One on the decoding procedure and results, and then a starter post on how to tune based on the revolutionary new discovery.

Hm, Audrey uses TypeScript for his tool, I think it would take days or weeks until I would get familiar with this programming language and the structure of his project

TypeScript in Visual Studio Code

Get the best out of editing TypeScript with Visual Studio Code.

[Waynemarlow]

Not sure though that the Canable Pro does the mV part either ?

Thanks for looking at Audrey's code.

Shame as the BESST Pro does exactly the same but in quite a simple and elegant way with a very good representation of what each part does to the torque curve but only the later M510 and M560 with FC2.0 or later controllers and not the M820 which you can only set assistance and acceleration, hence my assumption the M820 is a copy of the Ultra setup.

 

[Waynemarlow]

Although to be fair maybe the Canable Pro does but my betting that will be again only for the later motors with FC2.0
