Unable to connect DWM1000 in Two Way ranging and thus unable to calculate distance

I used the two way ranging example . Both the devices work individually . RX_BUFFER in responder is always getting updated with random values once turned on . Initiator is continously transmitting data as tx_count is increasing .
But they do not connect among themselves . I have no idea what could be the reason and how can I curate it . I have mentioned the link to both of these files below:
