How do I decode a Voltage Sensor event?

How do I decode a Voltage Sensor event?

The Voltage Sensor will generate events if the measured value rises above or falls below the configured thresholds.
 
Byte 0: 7-4
Byte 0: 3-0
Byte 1
Byte 2 
 
Byte 3 & 4
Protocol version
 
 
(4 bits)
Counter
 
 
 
(4 bits)
Message Type Code
 
 

(0x14)
Voltage Event
 
 

(0x01 in the example below)
Voltage
Measurement
 
 

(0x0810 in the example below)
 
 
 
Protocol Definition
              First 4 bits are defined by Radio Bridge for the protocol
              Next 4 bits are a counter that goes from 0 to F (Hex) and repeats
             
Message Type
                  0x14   represents the Voltage Sensor Message Type
 
Voltage Event
              Byte 2                         Description
                  0x00                              Periodic report
                  0x01                              Measurement has risen above upper threshold
                  0x02                              Analog measurement has fallen below lower threshold
                  0x03                              Report on change increase
                  0x04                              Report on change decrease
 
Byte 3 (Relative Measurement)
              The voltage measurement is in units of 10mV (range 0-3000)

Example of Voltage Sensor Event Message
10 14 00 08 10
1                                 Protocol Version (currently always 0x1)
0                                 Packet Counter (increments by 1 each message and wraps from 0xF to 0x0)
14                               Message Type Code (Voltage Sensor Event = 0x14)
00                               Voltage Event (Event 0x00 means the message is sent to a configured periodic amount of time)
0810                           Voltage Relative Measurement (Relative Measurement is = 0x0810 = 2064 mVolts = 2.064 Volts)
 
 
The Radio Bridge Console will generate the following output for this message:
Voltage Event: Periodic Report
Voltage Measurement: 2.064 Volts
