Re: [Discuss-gnuradio] Query on USRP2 and Host device Communications

[mleech]

Communications are generally initiated by the host.

If you explicitly specify the target device address using "addr=<your USRP2 device address>", then the host will communicate only with that USRP2 for the corresponding flow-graph.

The USRP2 has no firewalling abilities or anything like that, and doesn't really use an IP routing stack, so the intention is that it sit on a dedicated host-to-USRP2 Ethernet Link. It really isn't intended to live in a regular, routed IP environment.

Hi All

I have a  query motivated by the fact " USRP 2 device is communicating through an ethernet cable
with an IP address"

given multiple host machines and multiple USRP2 devices connected over a network.Is it possible to make sure
that give USRP device will communicate with a particular host machine over the network only.

Based on this Query we have following questions.Kindly please help us in clarify the following.

1. How does host PC running Gnuradio detects a USRP device?
2. In case of initial handshaking whether the USRP device or host machine initiates the handshake?
3. After the initial handshake ,how will the host machine keep track of the USRP device address?

Thanks in advance for the clarifications..


Thanks
