AT commands
Default
0xFF
Example
Sending the command ATPR 6F turn bits 0, 1, 2, 3, 5 and 6 ON, and bits 4 and 7 OFF. The binary
equivalent of 0x6F is 01101111. Bit 0 is the last digit in the bit field.
PD (Pull Up/Down Direction)
The resistor pull direction bit field (1 = pull-up, 0 = pull-down) for corresponding I/O lines that are set
by the PR command.
See
PR (Pull-up/Down Resistor Enable)
Parameter range
0x0 - 0xFF
Default
0xFF
IU (I/O Output Enable)
The IU command disables or enables I/O UART output. When enabled (IU = 1), received I/O line data
packets are sent out the UART. The data is sent using an API frame regardless of the current AP
parameter value.
Enable or disable the serial output of received I/O sample data when I/O line passing is enabled. IU
only affects the device's behavior when IA is set to a non-default value.
When IU is enabled, any received I/O sample data is sent out the UART/SPI interface using an API
frame. Sample data is only generated if the local device is operating in API mode (AP = 1 or 2).
Parameter range
0 - 1
Parameter
0
1
Default
1
IT (Samples before TX)
Sets or displays the number of samples to collect before transmitting data. The maximum number of
samples is dependent on the number of enabled I/O lines and the maximum payload available.
If IT is set to a number too big to fit in the maximum payload, it is reduced such that it will fit. A query
of IT after setting it reports the actual number of samples in a packet.
Parameter range
0x1 - 0xFF
