RX Packet: 16-bit address I/O frame - 0x83
Description
When the device receives an I/O sample from a remote device configured to use 16-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 API frame
format.

4-5 N/A MSB first, LSB last.
RSSI 6 N/A RSSI: Hexadecimal equivalent of (-dBm) value. For example, if RX
signal strength = -40 dBm, the device returns 0x28 (40 decimal).

Samples (if
enabled)
(see bit field
table
below)
11 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.
