How to detect whether Rx is receiving any packet from TX?

Hello Everyone,

I have configured two DW1000 in Tx and Rx mode, operating at 6.8 Mbps in Idle state and trying to establish a link b/w them. However, I am not sure whether the two radio are communicating with each other as I do not observe any change in RX current when TX is on or off.

Could you suggest a way that indicates that the RX has started receiving packets from the TX, may be any LED or pin in RX.

Thank you for your help in advance.
With Regards,
