Im using this one - and it has iPhone app but you have to pay for module - approx £27/$34 delivered to UK - that’s him much I paid. Plug and play 
If you have android @Ackmaniac has a free app- and you can get one of clone Bluetooth modules to go with it.
Btw - what step down converter are you using to have USB out?
It’s all over here - lengthy discussion on new firmware and vesc tool 
Thanks for the info mate. I’m on android so where would I get a clone module for ack’s software please? (I could search but I’m just being lazy! 
)
I don’t have usb power out, I just have a short extension lead from my VESC to the edge of the enclosure, so I can plug in the VESC without taking the enclosure off.
I am thinking about adding USB charging capabilities. If I did I’d use this module…
There you go you lazy ass! 
He has linked the module in his post, from AliExpress. Order it now to have it before xmass haha 
I wouldn’t get any other module as compatibility is a big issue, a lot of guys have problems getting them to work - unless you’ll find exactly same model on eBay uk … might be hard, pictures are usually stolen from listing to listing and module itself might not look like pictured one.
Thanks for the link with step down module!
I found even cheaper one on AliExpress
Look what I found on AliExpress
Or this one - quicker shipping from eBay

I’ll just have to get micro USB to female USB 2 extension or solder female USB onto it Winter project 
Edit 
Found one with female USB already soldered on from Ireland double the price at £4 but easier. Not sure how well USB 2 will hold to the enclosure…

Wait… I don’t have any space left in enclosure 
lol thanks! Although that particular one is no longer available. I found what looks to be the exact same module on Amazon though and I ordered with Prime, so it’ll be here tomorrow
I’m sure you could get those modules cheaper, I wasn’t sure how many cells you had in series so I looked for one that would cover all scenarios. I’ll be getting one for 8s which you can find a bit cheaper 
Haha! No space! 
That’s going to be my problem soon too!!
Dunno, I switched to FOC recently and it’s so much better.
Not sure if it’s a faulty DRV, as the VESC is working…
Just search @Ackmaniac thread I linked above for new link to the module - I think someone else also said it was no longer available and he linked new one - I might be wrong. You don’t want to have this problem:

Not sure if it’s relevant to the problem everyone here is having but I’ve had drop offs that happen because of power coming from the VESC for the receiver would dip when the voltage is getting relatively low on my battery (when it gets down from 42V fully charged to around 38V). With mine I have a custom receiver and adding a capacitor to the ground/vin on the custom recevier and on its radio (since they are separate pcbs in my case) gets rid of the drop outs entirely. I would take advice of others here to reproduce the problem then check for faults but assuming nothing comes through there would look at either adding capacitors to the power input on the receiver so it can deal with small dips in power from the VESC voltage regulator or try repositioning the receiver to see if it has any effect (further from the VESC). Might be red herrings but some things to try if you’re out of ideas.
Hi!
Tried the new FW but it does not work. I can’t get the remote to connect and I tried 2 remotes… any idea why?
Ishay
so did all your issues go away using FOC?
Pretty much, yes
