Example: Suppose an IO sample is received with analog and digital IO, from a remote with a 64-
bit address of 0x0013A200 40522BAA and a 16-bit address of 0x7D84. If pin AD1/DIO1 is enabled
as an analog input, AD2/DIO2 and DIO4 are enabled as a digital inputs (currently high), and AD3/
DIO3 is enabled as a digital output (low) the IO sample is shown in the API example in the table
above.
XBee Sensor Read Indicator
Frame Type: 0x94
When the module receives a sensor sample (from a Digi 1-wire sensor adapter), it is sent out the UART using
this message type (when AO=0).
Example: Suppose a 1-wire sensor sample is received from a device with a 64-bit address of
0x0013A200 40522BAA and a 16-bit address of 0xDD6C. If the sensor sample was taken from a
1-wire humidity sensor, the API frame could look like this (if AO=0):
For convenience, let's label the A/D and temperature readings as AD0, AD1, AD2, AD3, and T. Using the data in
this example:
AD0 = 0x0002
AD1 = 0x00CE
AD2 = 0x00EA
AD3 = 0x0052
