Cegalo Posted October 23, 2015 Share Posted October 23, 2015 Yesterday I updated 1.2.2 firmware to 1.2.7 and I have ridden 10 km.I think that it is a bit different to ride on it now, I mean it seems that that you need more effort to move the 9Bot1.It seems that the 9Bot1 tends to decelerate more than before (the sensation is that the 9Bot1 is heavier now)My driving mode is 3, the same than before.Also, the engine makes a little more noise.Do you have that impression too?

faipassa Posted October 23, 2015 Share Posted October 23, 2015 Don't think it is feasible (unfortunately I would say) Link to comment Share on other sites More sharing options...
OliverH Posted October 24, 2015 Share Posted October 24, 2015 I keep on 1.2.2 on our old (first batch) 9b1 e. Doesn't look serious what's going on at Ninebot. Link to comment Share on other sites More sharing options...
Viktiga Posted October 25, 2015 Share Posted October 25, 2015 I updated my 9bot one C+ yesterday. I think the wheel feels better then before and no unexpected shutdowns (yet). Link to comment Share on other sites More sharing options...
Cegalo Posted October 25, 2015 Author Share Posted October 25, 2015 Definitely, 1.2.7 firmware is a shit!I have been riding this morning and the speed in my 9B1E+ is too low compared with 1.2.2 firmware. I was nearly riding like a pedestrian and the app said 9 km/h.The 9B1 started to tilt in 22-23km/h and I can say that my speed would be 18-19km/h or less in 1.2.2 firmware.This is very dissaponting, now speed is reduced considerably in 9B1 E+Is 1.2.7 firmware bad designed or is it designed for 9B1 P and should not be installed in 9B1 E+?I have updated the app some days ago (it says 9B1 P support)Maybe there is sometning wrong with the models, the app and the firmware.It is a pity that such a great unicycle design does not go with a reliable firmware.

Gil Posted October 25, 2015 Share Posted October 25, 2015 Many thanks Viktiga for this original visit of Oslo. I am impressed by your velocity and ease on your Ninebot. It could be a good idea to have a video gallery on this site. Link to comment Share on other sites More sharing options...

Cegalo Posted October 25, 2015 Author Share Posted October 25, 2015 At last, I think I fixed it!I recalibrated the attitude sensor with the app and now the speed of 9b1 seems to be ok (only 3 km ridden since that) Link to comment Share on other sites More sharing options...
Phil Wright Posted October 26, 2015 Share Posted October 26, 2015 Hi Cegalo, sounds like you have it sorted.after I read your post, I remembered reading a post entitledWARNING http://forum.electricunicycle.org/topic/1528-w-a-r-n-i-n-g-ninedroid-apps-version-217-for-p-model-don-t-download-if-you-have-e-model/ sounds like youve got it sorted though so all good...

You reset it just by holding ninebot still while you click it from the app? Link to comment Share on other sites More sharing options...
Gil Posted October 26, 2015 Share Posted October 26, 2015 Nooooo ! You lock your ninebot and you let it still in a steady position. Then you click on the app function. Link to comment Share on other sites More sharing options...
LosCal Posted October 27, 2015 Share Posted October 27, 2015 and what does it sense? Link to comment Share on other sites More sharing options...
Gil Posted October 27, 2015 Share Posted October 27, 2015 No idea... but it works. There must be several sensors and it computes an average or something like that. Link to comment Share on other sites More sharing options...
