How do I decode an ABM (Acceleration Based Movement) event?

The ABM Sensor will generate events when movement is detected (that exceeds a configurable threshold). Note that this product should not be used for vibration detection. For vibration detection applications, such as detecting when a motor has turned on/off, see the Vibration Sensor products from Radio Bridge.

 

Byte 0: 7-4

Byte 0: 3-0

Byte 1

Byte 2

Protocol version

 (4 bits)

Counter

 

4 bits)

Message Type Code

 

(0x0E)

Movement Event

 

(0x00 in this example)

 

Protocol Definition (Byte 0)

              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 (Byte 1)

              0x0E represents the ABM Message Type

 

Movement Event

              Byte 2                         Description

   0x00                            Movement has started

   0x01                            Movement has stopped (see settling window)

 

Example of Movement Event Message

 

10 0E 00

 

1                                    Protocol Version (currently always 0x1)

0                                    Packet Counter (increments by 1 each message and wraps from 0xF to 0x0)

0E                                  Message Type Code (Movement Event = 0x0E)

00                                  Movement Event (Movement Event = 0x00 which means Movement started)

 

The Radio Bridge Console will generate the following output for this message:

Movement Event: Acceleration started
