6
Cellular component state mirroring (digital output)
This option is available in firmware versions ending in *17 and newer. When
D0
is set
to 6, the DIO0 pin mirrors the state of the cellular component's power monitoring pin
(V_INT). DIO0 is driven low (0V) when the cellular component is off or in LTE PSM
mode and driven high (3.3V) when the cellular component is powered and active. This
function is primarily for use with USB Direct or Bypass operating modes. Note that
while the XBee is asleep (such as Pin Sleep or Cyclic Sleep), DIO0 will be driven low
and will not update until the XBee leaves sleep.
