Hello Lee,

The sample code supports PD, you will find a manual where you can see how to modify the code for all the different available power and port modes. You can request the sample code here.

Regards,

Diego.

Hello Lee,

The DISCARD alert is because the channel was busy with an incoming message, it is not a transmission error, but it is discarded due to the channel activity. Please wait for a time (until the channel is clear) and retry the message.

Regards,
Diego.
