Hi,
I have some problems with my experiment.
What I want to do is described as follows.
USRP1(device1) USRP1(device2)
±-----------+ ±-----------+
| | @450MHz | |
| | data |db1: |
| db1: --------> FLEX400(A)|
| FLEX400(A) <-------- |
| | data ack| |
| | | |
| | | |
|db2: | data |db2: |
| FLEX400(B) --------> FLEX400(B) |
| <-------- |
| | data ack| |
±-----------+ @470MHz ±-----------+
Now I have two USRP1.
Each of them is equipped with two RFX400 daughterboards.
And I hope that device1’s A can communicate with device2’s A at 450MHz,
and
device1’s B can communicate with device2’s B at 470MHz.
For example, device1’s A sends data to device2’s A ,and when device2’s
A receives the data, it will send
an ack back. Finally device1’s A will receive the ack from device2.
The same thing will happen in B boards at the same time, but in
different frequency. Also B boards will send
different data from A boards.
So every daughterboard has the capability to transmit and receive
payload.
My first qusetion------------>Is this possible to implement on
USRP1???
If it is possible, can I solve it by the following way?
Now I try to create new txpath and rxpath under the top block to solve
the problem.
###########################################################################
#for db1
self.txpath = usrp_transmit_path.usrp_transmit_path(mod_class, options)
self.rxpath = owl_rxpath.usrp_receive_path(demod_class, callback,
options)
#create new txpath and rxpath for db2
self.txpath2 = usrp_transmit_path.usrp_transmit_path(mod_class,
options2)
self.rxpath2 = owl_rxpath.usrp_receive_path(demod_class, callback,
options2)
##############################################################################
And I will create new source and sink for db2.
My second qusetion------------>Is that a possible way to solve the
problem?
If it’s not or there is any better
way to solve this problem, please tell me.
Thanks for help!
I just really want to know the answers.
