Did you get one of these monitors?Here is a cold cranking test without fuel or ignition (fuse removed) on a tired but freshly charged 9 year old Honda OEM Yuasa YTZ14S battery.
The stated cranking voltage from the initial turnover of this 3 second test is a bit misleading. As shown earlier a normal start occurs within one second.
Since the engine was not started during this cranking test the voltage for the remaining duration of the cranking is varying between 9 and 12 volts which is more than adequate to supply enough voltage to the ECM to start the engine. Starting vs. ending voltage has about ½ volt drop which is reasonable.
After reading hedgehog's post I tried six 0's and I was finally able to see the BM2 with my (new) Motorola phone, but the app *still* could not see the monitor.When I was able to see the device with my phone I tried both 0000 and 1234 as passwords. Neither worked.
On my wife's phone, it did not ask for a password.
It connected (paired) on her Samsung phone, just would not pair on my Motorola phone.
I'm thinking it's more a phone issue rather than BM2 issue. In any event, I can just use my wife's phone to see what I need. I was just interested in determining the status of the battery while cranking and while charging before committing to purchase a new battery...
Chinese software is kind of like spyware: it wants Bluetooth to connect to the device, GPS for your location, and Cellular Data to phone home and report you.After reading hedgehog's post I tried six 0's and I was finally able to see the BM2 with my (new) Motorola phone, but the app *still* could not see the monitor.
Then I read the reviews for the app in the Google Play Store and several reviewers mentioned that, if you had trouble connecting to the monitor, turn on "location services" (GPS) on the phone. Who knew!?!
When I did that then the app was *finally* able to see the monitor.
So now I can see the BM2 on my own phone but the app constantly cycles between "connected" and "unconnect".
So... I'm getting closer. Guess I'll keep playing with it...
