You can pack "Hello World" string as paylaod then use send_pkt(payload) on the transmiter side. similarly unpack the payload at reciever to convert into string.

you need to use same formating for pack and unpack at Tx & Rx respectively. I am assuming you are using packet radio.

When we send and recieve using USRP boards and GNU SDR, on the recieve side usrp setup, demodulator connects to gr_correlate_access_code_bb which connects to framer_sink. framer_sink pushes the assembled packets into the target queue. Can we extract the pkt here to read the data? How can we send a "Hello World" string on the transmit side usrp sdr setup?

Any suggestions?

I was about to ask a similar question:  "Has anyone implemented
a simple RTTY mode?"  I suspect keyboard to keyboard RTTY would
be the simplest possible "Hello World" type example.
