Luna BBSHD Ludicrous V2 controller documentation

[grahamgfr]

Solved !! Back on the app now !

[grahamgfr]

Just sat down to have another go at setting up and the VESC Luna phone app has presented me with this message. What's the best solution please ? Thank you

[grahamgfr]

Thank you for the confirmation.

I just checked the latest eggrider firmware with the latest bbshd firmware and seems to be working ok. Eggrider is displaying 84V here.

[grahamgfr]

Thank you again Marcos, let me get my work shifts out the way and I'll update you.

Okay, so here are the checks I'm running:
* Updated the eggrider firmware from within the eggrider andoid app. Firmware included in their app is v2.5.61
* Checked that PAS levels are set correctly. For that I use the desktop version and look at General->Current. I see that "Max Current Scale" field changes when changing PAS level in the display. On startup the last PAS level used is correctly acquired.
* With a lab supply providing 61V I see that the eggrider shows 61V, despite the controller is supplying the display with 12V. I need a second supply to bump this to 84V for proper coverage, will do it tomorrow.
* I checked that when the controller is configured for 72V battery the max voltage threshold is set to 86V.

So for now it looks like software wise is okay. If you have the app running could you make a brief datalogging so I can take a look? That way I can see dozens of variables at once, maybe there is one going off spec and makes it limit the torque.

Cheers Marcos, I actually tried both versions but from now on i'll be using the stable one.

[marcos]

graham, did you use eggrider_fw_v2.5.61_stable.zip firmware?

I couldn't find my eggrider today, I think I left it in the bigger lab but the ludi v2 manual says "version > 2.5.58_beta". That beta now became stable, so "v2.5.61_stable" should be the correct file, which is prone to confusion. I want to test that firmware anyway to be sure, but meanwhile I thought I should let you know

[grahamgfr]

Thank you but I'm pretty certain I have changed the settings to 72v via the Luna app,

[choochoo]

You’re using a 72v battery. The controller won’t spin the motor until you use the Luna VESA android app to change the battery type to 72v.

[grahamgfr]

Thank you, any help is very much appreciated

[marcos]

If the wheel spins but its producing low torque, it sounds like the system is in PAS level 1 (the default on startup)
If the eggrider is showing 12V it seems the eggrider firmware is not right, it should show the battery voltage even at 72v. Let me check if the link to eggrider firmware is okay. An old eggrider firmware IIRC could show level 9 but on startup but the controller was still in level 1 until you press a + or - button

Good Afternoon Everyone,

I'm after some advice please if I may, I've been lucky enough to get my hands on a V2 (Thank you again) and I'm in the process of trying to set it up. This is my 3rd day of trying !

I've come from an original Ludicrous and a couple of ASI BAC 800's. I'm running a 72v battery.

So I purchased a brand new Eggrider to go with the V2. Connected it and switched on, got it activated, downloaded and installed the beta version from the link provided although the build number was different to the one on the installation instructions. Protocal chosen was Bafang. Downloaded the correct Luna Edition app via the links provided, seemingly set it to 72v on the app, Firmware showing FW 5.3 and HW Luna_bbshd.

The above all went without a hitch and was completed quickly. Tried the throttle and the motor moved, had response and mildly revved up with the wheel in the air And this is where the problem started, I had livedata coming through on the Luna app (looks great) but nothing happening on the Eggrider display nor the Eggrider app. It was then I discovered it had zero power with the wheel on the ground. Ok I thought maybe a setting I'm missing so for the next 2 days I have tried everything...

I've tried the different versions of the EggRider firmware provided, uninstalled and reinstalled both apps, I noticed on the EggRider that once the protocol of Bafang is chosen I get 4 different timeouts suggesting it can't connect. No functions seem to make any difference the only live information I get on the Egg is the voltage that reads approx 11.8 which I know is correct for the 72v version. Only voltage on the phone display too. I noticed on the Egg with the later version it showed error code EFF.

I've now run out of ideas, can someone please help ?

Thank you,
Graham

mileage is built into the bbshd display (it doesn't depend on the controller), and range estimate is not on the roadmap yet as it depends on how good is the battery estimation

Thanks Marcos, I got it to work with a new Android phone. Is there a timeline to when you will provide a firmware upgrade to the stock controller so I can see the mileage and range estimates? Thank you.
