SS_TWR not working

I am working with DWM 1000 for ranging and communication . I have been able to utilize simple transmit and recieve but devices do n ot get connected when I try utilizing the two way ranging.

The rx_buffer in the responder fills up with garbage value and thus never respond as it does not match with POLL MESSAGE . In case of initiator tx_count keeps increasing while the rx_buffer is empty.

I am looking for some help with this as I have not been able to figure out the exact reasons for devices not getting connected . I assume this has something to do with tiing but not sure.
