Thanks. I just purchased an LELink bluetooth OBDII adapter on eBay for $20, per Turbo3's iOS-related May 16th post near the end of the thread you mentioned.
Has the adapter worked as expected? Can you leave it in place without draining the 12 volt battery? Does it restart seamlessly each time you start your Leaf? Still holding out for consistent good results with iOS bluetooth LE.
Yes, yes, and yes!
I put LeafSpy on an old unused iPhone 4s which I leave in the car 24x7. The LElink bluetooth OBDII adaper is plugged in 24x7 as well. Now every time the car comes home, it automatically connects to my WiFi and uploads the data to DropBox which I can then view from my computer or my personal phone.
So LeafSpy and the LElink are working great, however there is an unfortunate limitation which I believe is caused by the car, not LeafSpy. I only get data when the car is turned on or charging - despite continuous power to the LElink.
So back to my 12v battery dying overnight every six months problem. If the problem is due to a parasitic draw that occurs every six months at night, the LeafSpy/LElink won't really help me. On the other hand, if the problem is due to the DC-DC converter failing every six months - unnoticed by me during the day before the battery dies overnight, then the LeafSpy/LElink should confirm this.
Next I may install a low battery voltage alarm with an extra-loud alarm so I can catch a parasitic draw in the act and maybe start pulling fuses to see what stops it - at 3:00am. But of course, I have around 5 months to find one and get it installed since it just died about a month ago.
BTW, I've been working with Nissan Aftersales and 3 different dealer techs on this for years. The most recent development is that Nissan is sending their own Leaf tech to my dealer to meet me about a month from now. That's after they decided not to buy back the vehicle. They did give me a free Gold 48-month warranty extension, which covers everything but the drive battery, so if I can ever figure this out myself, I should be able to get them to fix it.
And now to make matters worse, my drive battery capacity seems to be dropping exponentially instead of logarithmically as it's supposed to - and I'm at 58k miles - but that's for another thread.
I believe I'm in the Tesla Model 3 queue around 100,000.
