Periodic I/O sampling

Periodic sampling allows a device to take an I/O sample and transmit it to a remote device at a periodic rate. Use the IR command to set the periodic sample rate.

To disable periodic sampling, set IR to 0.
For all other IR values, the firmware samples data when IR milliseconds elapse and the sample data transmits to a remote device.

The DH and DL commands determine the destination address of the I/O samples.

Only devices with API operating mode enabled send I/O data samples out their serial interface. Devices that are in Transparent mode (AP = 0) discard the I/O data samples they receive. You must configure at least one pin as a digital or ADC input to generate sample data.

Although samples may be taken every millisecond, IR should be at least 20 milliseconds. This allows time for OTA transmission and output on the serial port of the receiving device.

A device with sleep enabled transmits periodic I/O samples at the IR rate until the ST time expires and the device can resume sleeping. For more information, see Sleep support.
