I/O Commands
AT
Name and Description
Command
Parameter Range
Default
Pull-up/down Resistor. Set/read the bit field that configures the internal pull-up/down
resistor status for the I/O lines. "1" specifies the pull-up/down resistor is enabled. "0"
specifies no internal resistors are used. The input will be floating.
Bits:"
0 - DIO4 (Pin 24)
1 - AD3 / DIO3 (Pin 30)
2 - AD2 / DIO2 (Pin 31)
3 - AD1 / DIO1 (Pin 32)
4 - AD0 / DIO0 (Pin 33)
5 - RTS / DIO6 (Pin 29)
6 - DTR / Sleep Request / DIO8 (Pin 10)
7 - DIN / Config (Pin 4)
8 - Associate / DIO5 (Pin 28)
9 - On/Sleep / DIO9 (Pin 26)
10 - DIO12 (Pin 5)
PR
0 - 0x7FFF
0x1FFF
11 - PWM0 / RSSI / DIO10 (Pin 7)
12 - PWM1 / DIO11 (Pin 8)
13 - CTS / DIO7 (Pin 25)
14 - DOUT / DIO13 (Pin 3)
Pull-up / down direction. Set/read an internal pull-up or pull-down resistor for the
corresponding bits in the PR command. If the bit is set, an internal pull-up resistor is
used. If it is clear, an internal pull-down resistor is used. See the PR command for the bit
order.
PD
0 - 0x7FFF
0x1FBF
RSSI PWM Timer. Time the RSSI signal will be output on the PWM after the last RF data
RP
0 - 0xFF [x 100 ms]
0x28 (40d)
-
reception or APS acknowledgment.. When RP = 0xFF, output will always be on.
%V
Supply Voltage. Reads the voltage on the Vcc pin in mV.
-0x-0xFFFF [read only]
Voltage Supply Monitoring. The voltage supply threshold is set with the V+ command.
If the measured supply voltage falls below or equal to this threshold, the supply voltage
V+
TP
will be included in the IO sample set. V+ is set to 0 by default (do not include the supply 0-0xFFFF
voltage).The units of this command are mV. For example, to include a measurement of
the supply voltage when it exceeds 3.3 V, set V+ to 3300 = 0xCE4.
0
-
Reads the module temperature in Degrees Celsius. Accuracy +/- 7 degrees.
0x0-0xFFFF
1° C = 0x0001 and -1° C = 0xFFFF. Command is only available on PRO module.
