4LIGHT RING STATUS
State Light Ring Color Pattern Description
Idle/Debug Slowly flashing orange The system is in Idle or Debug state where the
HostMCU Firmware stops discovering the power
receivers, performing power receiver queries, or
scheduling TPS. The HostMCU Firmware, however,
still handles new commands and asynchronous
messages from power receivers. The system enters
this state when the Pause command is used at the
command line interface (CLI) or in the Cota DTU.
The system also remains in this state if the Debug
Mode parameter is set to true in the
Cota_Config.json file. To exit this state, enter
the Run command at the CLI or in the Cota DTU.
Calibration Purple segments progressing The system is performing power transmitter
calibration and initialization. The power transmitter
enters this state automatically upon starting up, but
users can also initiate a manual calibration in the
Cota DTU.
Wait for Power
Receivers
Light red background color with one bright
light segment moving slowly in circle
The power transmitter has been initialized and
calibrated, but it does not detect any power
receiver devices within the vicinity.
Ready Green background color with one pink light
segment moving in circle
The power transmitter detected at least one power
receiver and is ready to deliver power to that power
receiver, however, the power receivers might not
have been authorized or enabled to receive power.
Users can use the Cota DTU to register and enable
power delivery.
