Dear all,
I mean if I open the Rx or Tx then the function will run all the time, I want
to know how to let them stop after they recieve a fixed length package?
Thanks all!

use the recv function with the enumeration that indicates to stop receiving
once get the specified number of samples.

Hello. I need to change the clock of the USRP1 for the OpenBTS project, but
I find incoherent information between your page and the page of GNUradio.
That information is:
In GNU radio:

> Reclocking the USRP-1 for OpenBTS Hardware modifications to the USRP to

- Solder SMA (LTI-SASF54GT) connector to J2001
- Move 0 ohm 0603 resistor R2029 to R2930
- Move 0.01uF 0603 capacitor C929 to C926
- Remove 0.01uF 0603 capacitor C924
The incosistence is:
GNUradio: Move C925 to C926.
In Ettus: Move 0.01uF 0603 capacitor C929 to C926
Thanks
