Data transfer through Pre-cog

Hi
I am trying from the past week to use the pre-cog library for data
transfer between two USRP N210 devices. I have tried a number of
configurations by replacing many blocks and modifying the Python code.
I
managed to transmit just a single packet and then the transmitter stops
with no error. The spectrum analyzer also shows just a single packet
transfer.

Can some body guide me on how to use the pre-cog simple trx for data
transfer.

Regards
