How to make 8 bits sample works

GNU Radio
1

Hi all, I want to let my application work on 8 bit sample mode.
I have test and checked that 8 bit resolution sample can meet my
application’s accurate need.
I test my application that run it on 16 bit sample and shift the read
data
right 8 bits then shift left 8 bits. My application works fine.
But when I let my application work on 8 bit sample mode, my application
can
not work, I wonder the logic that usrp hardware produce 8 bit sampled
data.

Thanks!

What does the received 8-bit data look like? How is the received 8-bit
data different from the 8-bit data you have generated from 16-bit data?

I have fix the problem which is my application bug.
