RX (Receive) Packet: 64-bit address IO frame - 0x82
Description
When the device receives an I/O sample from a remote device configured to use 64-bit addressing, the
I/O data is sent out the UART using this frame type
Format
The following table provides the contents of the frame. For details on frame structure, see
Frame data fields
Offset
Total number of samples Description
Frame type

N/A
0x82
64-bit source address 4-11
N/A
MSB first, LSB last.
RSSI
12
N/A
RSSI: Hexadecimal equivalent of
(-dBm) value. For example, if RX
signal strength = -40 dBm, the
device returns 0x28 (40 decimal).
Status

N/A
bit 0 = reserved
bit 1 = Address broadcast
bit 2 = PAN broadcast
bits 3-7 = [reserved]
Number of samples
14
N/A
Total number of samples.
Channel Indicator
(see bit field table
below)
15
MSB
Indicates which inputs have
sampling enabled (if any).
Each bit represents either a DIO
line or ADC channel. Bit set to 1 if
channel is active
16
LSB
Digital samples
(if enabled) (see bit
field table below)
17
MSB
If any of the DIO lines are enabled
in the Channel indicator, these
two bytes contain samples for all
enabled DIO lines. DIO lines that
do not have sampling enabled
return 0. If no DIO line is enabled,
no bytes are included in the
frame.
