Hi I am making a project on BeagleBoard which collects different data.
Now I want to interface a 433MHZ transmitter to the BeagleBoard and receive the transmitted data on a computer using SDR(Software defined Radio).
I don’t want to use two BeagleBoard, it’s OK if the Transmission speed is low with the SDR.
So If anyone can suggest me ways in which I can interface the transmitter to send data on RF and receive it on SDR.
Thanks

First question I'd have is what is the legality of using that band in
your area, and the exact category of transmitter...
ISM radio band - Wikipedia (interesting -- I have loads of
remote temp/hygro sensors that are 433MHz, but this indicates that the band
is not valid for the US... But likely falls under the Part 15 rules that
they do not cause interference, and have no protection against interference
from licensed uses)
Would likely be easier to interface a BTLE, WiFi, or ZigBee system as
those are designed for computer digital data. 433MHz radios probably need
to have you code the entire protocol... CW (on/off), (A)FSK (shifting tones
ona fixed carrier). Using HDLC bit-stuffing and handshaking (Amateur Packet
Radio)...
