I'm getting some great help on the MIT app inventor forum on the basic BT RX and drawing the meter levels.

I'm streaming 1 byte value per meter and a 2 byte header over BT to the android app. The 2 bytes just mark the beginning of a packet the 8 bytes meter values.

since I'm using every possible value of a byte for the meter value I had to go for a 2 byte header to mark the start of the packet.

As i'm typing this I've just realized I should maybe use meter values between values 0x00 and say 0xF9 and use the remaining values 0xFA , 0xFB up to 0xFF to mark the beginning of a packet / code for what kind of meter packets they are !

the bunch of numbers by GAIN are meter values just for debug.
