How to access Elithion or Zilla via an Android tablet (instead of having to connect a PC via USB/serial cable):
I bought 2 serial-bluetooth adapters from here:
About $59 each. These ones allow the baud rate etc... to be set via the serial port, via bluetooth, or to be defaulted to 9600 via external dip switches.
The software also allows the bluetooth device name to be customized, and the PIN to be changed (important - don't want drive-by changes to my controller!).
I then installed a spp bluetooth serial terminal app for android - there are a bunch of them that are free... I use "Blueterm", "Bluetooth SPP" and "Sena BTerm". It is nice to find one with a usable "esc" key...
Zilla setup with 9600 baud - Elithion setup with 19200 baud - both work great. Now I can see what's happening from my Android phone.
The reason I did this was I got stuck once. The BMS will give an error for an over-charge condition (ie charger fails to stop) or for an over-discharge condition. I trigger on the error signal to create a ground for a relay - ie if there is an error, you cannot charge (this is not good for an over-discharge condition). I suppose I could wire in a switch to the relay to force the ground (and allow charging) - with the Android/bluetooth serial option I can now remove the error and start charging... Way better than those Palm solutions for Zilla too....
I would love to see Android apps that make better use of the Zilla/Elithion data stream via bluetooth - a removable dash android tablet would be great in my car!
