Is this only since the 143 update that came out recently ? I haven't had this happen, either on the older one or the newer one.
I'm thinking I might have an old firmware on my OBD LX but how do you upgrade the firmware? The Android app connects but since (I'm guessing) the imiev isn't OBD compliant it fails.
Most of the time it just lights up a bunch of warnings lights on the dash and I have to turn the car off and on and remove the LX to clear them.
There is a trick to updating the firmware on an OBDLink LX on an i-Miev. Instead of choosing connect, go into Settings->Firmware Updates, then in the top right of the screen press the triple dot icon (sorry, not really an Android user to know what that icon is called!) and choose Firmware Recovery.
It should now scan your adaptor to find what model it is and then download and install the firmware.
The versions available are 3.4.1, 4.0.0 and 4.3.0. If your adaptor has never been updated before the current reported firmware will probably say 0.0.0! (I've reported this bug to OBDLINK support)
By the way, I've run all three firmware versions on mine whilst troubleshooting intermittent disconnection issues, and they all work to some degree, and I have never seen the screen go black - so that is more likely a problem with your android device. Is the app crashing ? Or is the device going into screen lock mode perhaps ?
Another thing is that older versions of the OBDLink LX adaptor have a bug in the bluetooth module firmware (separate to the STNxx firmware, which is the one you upgrade when you do a firmware upgrade) which can cause bluetooth pairing to be frequently lost - especially if Canion is left running while the car is turned off.
This is not a Canion bug but a bluetooth firmware bug in the adaptor - OBDLink support have sent me another adaptor with a later manufacturing date which reportedly has an updated bluetooth firmware and sure enough - the problem I was having with frequent loss of bluetooth pairing and having to repair the device all the time is solved.
It's not clear whether all new adaptors sold from today have this updated firmware (and if so when the cutover date was) or whether they sent me a special adaptor with a test version of bluetooth firmware.
Finally in case nobody has picked it up yet - one of the changes in Canion 143 is that the instantaneous miles/kWh figure on the left hand side was grossly in error before - under reporting the figure by nearly a factor of two. I reported this to the Canion devs and got an email back saying it would be fixed in the next version and I can confirm 143 fixes this bug.
