TT02 RS232 command settings
UART Setting: Baud rate 19200, Data bit 8, Stop bit 1, No Parity, ASCII
Activate Trigger
1. Activate by Button:
If Success:
TT02 --> COMPUTER: "BBBBBBBBBBBB” 12 bytes,
- BBBBBBBBBBBB: Bluetooth Address
If Fail,
TT02 --> COMPUTER: "$TFAIL#" 7 bytes,
2. Activate by UART:
COMPUTER --> TT02: "$TXXXRR#", 8 bytes
- $TXXXRR# = Command Code
- $TXXXRR# = Trigger Timer in seconds (HEX)
Ex: XXX = 0x64, Trigger 100s.
- $TXXXRR# = RF received threshold in minus RSSI (min RSSI).
- Ex: RR = 0x4B, Receiving RF RSSI need above -75 dBm
If Success, for Sensor Format 2 (Advertising):
TT02 --> COMPUTER: "$TBBBBBBBBBBBBPPPPTTTTVVVV#” 27 bytes,
- BBBBBBBBBBBB: Bluetooth Address
"$TBBBBBBBBBBBBPPPPTTTTVVVV#”
- PPPP: Pressure in PSI
"$TBBBBBBBBBBBBPPPPTTTTVVVV#”
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 10 KPA , so will display
negative character.)
TTTT: Temperature in Fahrenheit
"$TBBBBBBBBBBBBPPPPTTTTVVVV#”
Ex: TTTT = +200, Temperature is 200F
- VVVV: Battery in mV
"$TBBBBBBBBBBBBPPPPTTTTVVVV#”
Ex: VVVV = 3200, Battery is 3200mV
If Success, for Sensor Format 1 (IBeacon):
TT02 --> COMPUTER: "$TBBBBBBBBBBBBMMMMNNNNRR#" 25 bytes,
- BBBBBBBBBBBB: Bluetooth Address
"$TBBBBBBBBBBBBMMMMNNNNRR#"
- MMMM: IBeacon Major Field
"$TBBBBBBBBBBBBMMMMNNNNRR#"
- NNNN: IBeacon Minor Field
