I had a minor issue today: driving along, Leaf Spy Pro running, then the ELM losses connection (I have a cheap ELM, it just does that occasionally), then the phone sleeps. At the next red light, I reset the ELM, wake up the phone, enter my PIN (required, don't ask)... The ELM reconnected and things were working again.
It all worked out, but waking up the phone, logging back in, etc. due to a bluetooth blip was a pain. I have the "Stay Awake" option selected, but that seem to only work if there is an active bluetooth connection. I like that idea, it is smart, but I guess my request is that 'stay awake' doesn't give up so fast. Maybe it allows the phone to sleep after 10 minutes or so of no connection or activity?
