IR (Sample Rate)
Set or read the I/O sample rate to enable periodic sampling. When set, this parameter causes the
device to sample all enabled DIO and ADC at a specified interval.
If you set the I/O sample rate to greater than 0, the device samples and transmits all enabled digital
I/O and analog inputs every IR milliseconds. I/O Samples transmit to the address specified by DT.
To enable periodic sampling, set IR to a non-zero value, and enable the analog or digital I/O
functionality of at least one device pin (see D0 (DIO0/AD0)-D9 (DIO9/ON_SLEEP), P0
(DIO10/RSSI/PWM0 Configuration)-P2 (DIO12 Configuration).
WARNING! If you set IR to 1 or 2, the device will not keep up and many samples will be
lost.
Parameter range
0 - 0xFFFF (x 1 ms)
Default
0
TP (Board Temperature)
The current module temperature in degrees Celsius in 8-bit two’s compliment format. For example
0x1A = 26 °C, and 0xF6 = -10 °C.
Parameter range
This is a read-only parameter
Default
N/A
%V (Voltage Supply Monitoring)
Displays the supply voltage of the device in mV units.
Parameter range
This is a read-only parameter
Default
N/A
I/O line passing commands
The following AT commands are I/O line passing commands.
I/O Line Passing allows the digital and analog inputs of a remote device to affect the corresponding
outputs of the local device.
