- BBBBBBBBBBBB: Bluetooth Address
"$RRBBBBBBBBBBBBPPPPTTTTVVVV#”
- PPPP: Pressure in PSI
"$RRBBBBBBBBBBBBPPPPTTTTVVVV#”
Ex: PPPP = 1234, Pressure is 123.4PSI
PPPP = -024, Pressure is -2.4PSI
(2.4 PSI is 17 KPA, 83 KPA (Raw data) - 100 KPA = 17, more than the MIN limit 10KPA ,
so will display negative character.)

"$RRBBBBBBBBBBBBPPPPTTTTVVVV#”
Ex: TTTT = +200, Temperature is 200F
- VVVV: Battery in mV
"$RRBBBBBBBBBBBBPPPPTTTTVVVV#”
Ex: VVVV = 3200, Battery is 3200mV
