Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Don't want to spam, but if anyone is considering flashing their unit -- could you please dump the FW using the method nick / geeksville mentioned first?

I'm the idiot that didn't realize this FW isn't compatible with the BBS02... :lol:

Thanks in advance! :bigthumb:

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

If anyone is planning on flashing the to a fresh device, I'd appreciate if you could try grabbing a copy of the existing factory firmware off the device using the method suggested on the first page of this thread. Thanks!

head --> desk...

Guess I didn't realize this was for the TZD2 only, not the bafang motors.... Oops.

I take it there's no chance of reverting the FW?

Failing that, it looks like I may have to write my own version for the BBS02....

Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Quick side question: is it possible to use another openocd compatible flashing tool? I have a flyswatter2, ft2232h, and an olimex usb-tiny-h at my disposal.

Re: BBS02 750 Unpowered drag?

I am having a problem with the power to my bbs02 shutting off. Frankly, I generally don't, immediately, notice that it has happened. Unless I am going uphill, or into the wind, it still pedals easy. Yep, looks like you're correct. I've driven it about 100 miles so far, and it does seem to be quite ...

Re: BBS02 750 Unpowered drag?

Was dreading the prospect of doing a teardown already on it, or shipping it back to china :) With the chain off the chainring, I can get it to spin about 4.5 times backwards (ratchet clicking), and maybe 1 - 1.5 revolutions forward. I do also notice a bit of a click...

BBS02 750 Unpowered drag?

Title says it all. This is my first build, and while it seems to mostly be coming together, one thing I'm noticing is that there seems to be a fair amount of "drag" on the pedals in unpowered mode... quite a bit more than a regular bike bottom bracket. Is this normal / to be expected, or is there an...
