I remember seeing this on one of the facebook groups, I couldn't find any previous posts about the bike or battery from the user but I believe this was because they deleted them. They didn't want to give much information out when it happened irrc, people were asking about the battery but due to the watt hours it had to have been a soft mount - diy solution. I actually just recently went looking for it again but couldn't find it due to FB's :poop: search function. I too would like a link if you have one
 
Anybody get a DP245.can with bluetooth 5.1 that works with the Bafang GO+ app?

It's like the Bafang Go+ app is very elusive. No one seems to been able to get it working and I've scoured the internet for info to no avail. Has anyone ever asked Bafang directly what's up with this app and what hardware it works with? Does anyone have a contact with Bafang or a reseller that may be able to provide this insight?

I found this review of a Frey bike using a m510. Says Go+ works with a C245 using bluetooth 5.0 Frey Evolve Review with Bafang M510 Mid-Drive Motor！

I found a thread that notes the Go+ only works with the version of the 245 that is bluetooth 5.1 vs bluetooth 5.0

shows how there is so much contradictory information on this. Guess we need someone to physically try it or get someone directly from Bafang to confirm the exact requirements. I'm hoping this app will work, as I don't really want to invest in a Besst tool if I don't have to
 
To the folks that have gone through the ordering and build process, can you make any recommendations/is there something that you would do differently?

Cheers.
 
Ya that is why I was researching. All I want to do is adjust the assist levels and possibly do a calibration. Much better to do that with the GO+ app.

For me it is all about managing expectations. SZZS had my frames painted and ready to go 4 months ago. But there are a lot of aspects that are out of their control. First there are festivals and shows that take them away from the shop. There have been delays in getting M820 and batteries. Then shipping by boat is not like fedex air. The shipment now has to go by DG dangerous cargo ship. If they don't have full containers they may wait to fill them up before they leave. Might have bad weather on the way delaying arrival. Then you have to wait for customs.
I think now that the original adopters have proven that this frame is a viable option there may be a much higher demand on M820 and associated parts. We have this frame, Lightcarbon, Tantan and others now using the M820. So it could get harder to get one. It would also be reasonable that the prices might go up.
So I don't think it is off to consider 4 months to be the delivery time.
 
I have 245 not working with go+

The problem with Bafang, at least outside of China, is a lack of documentation. Also the stupid decision not to have a commomly available tools for adjusting parameters without the need for a userid and password on the company website.

How much does the best tool cost?
Click to expand...
It is really not the cost, you can't use it unless you have an account with Bafang. Designed for retailers. There are work around scripts out there ecetera but you don't get a password or account when you buy one.

There is the K1 which is a third party effort. It does not require passwords etc but it is a text based device that reads a configuration file when it boots up and sends commands to change whatever you have in the file, upon booting.

But to be a modern player Bafang has to step up and get an app running that does all this via bluetooth. Ridiculous if some of the DPC245.can with work, that have Bt 5.1 , and some won't and you can't tell which one you have and they both have the same part number. So you can't even buy one purposefully.

Judas Priest and I thought Shimano was bad with their software.

The vendor where I bought the motor is selling me the besst tool for 100$ and he gave me the codes

Today was the "hour of power" in decent heat!🥵 97+F°

I went full boost-mode in rolling hills terrain with 65% flowy climb and a smooth, bermed downhill ripper 35%.

Just 53 minutes of 9.2 miles in all turbo to stress test the M820-75Nm performance tolerance during fairly hot conditions. I had 82% battery remaining.

I didn't notice any power drop-off!👍

Personally, I like to climb as an ex- analoger, so I've never been a huge fan of powering up switchbacks moto-style, especially in dealing with strong motor overrun and the drivetrain abuse potential.

The M820 had a little overrun in Boost mode, but it's minimal and can be used smoothly and predictably when climbing most tech. So, it yields a pedal-bike-feel still without being crazy like full-powered or wimpy like lower-to-mid powered motors. IMHO💪😇

Next ride is in the morning for cooler temps and on a fairly steep switchback-oriented mountain climb. This should really put it to the test for my typical riding terrain, and hopefully provide more testimonial feedback!🚵

Hey @TCFlowClyde was this ride report done with stock OOTB tuning? No BESST tuning?
I'm just trying to gauge motor feel and response.

Yes. That Frey review seems more like a marketing and press release. It's unclear if they actually used the app.
In the middle somewhere they say they would release a video or review of the GO+ app itself. This was in Feb.

In fact, probably like all who searched before me, there's no evidence that this app works on ANYTHING.
No reviews, no videos, no comments on the app stores, anyone who knows anybody with a working example?

My gut tells me Bafang has screwed the pooch on this one.
My gut tells me BESST is my best hope for tuning.

I use the stock tuning...seems gradual and significant at each level for the M820 using the DPC245 display. 👍

I know Jim at Light Carbon speculated that the BEEST tool might provide M820 tunability, but honestly when using it for the M600 motor it sucks. You can't tune the M600 at this point in time. I also thought the stock power modes setup worked, so I only used the BEEST to calibrate a new controller recently.

The only thing I want to change in the M820 is the weak-a$$ walk mode that I mainly use when shifting in the stand or walking it up stairs to my house. 💪

I think the mobile app is still a low priority for Bafang and developing. However, it would sure be a major selling point to level up with the competition. Com'on Bafang great motors, but step up your user-friendly app game!😁

Ha. I didn't read your's before I made my "...step-up your game for the app!" comment. 😝

Too true.💯 Bafang go forth into the 21st century with your app. Ditch the 1980s BESST Atari-console-vibe. (No offense to Atari!🤖).😉
