How to make sure WARP nodes sending packets via wireless medium?

Hi,

How to make sure WARP nodes sending packets via wireless medium not via the ethernet?

Thanks!

You'll have to provide much more information about your setup - how many nodes, running what hardware/software designs, Ethernet connections, etc.

Re: How to make sure WARP nodes sending packets via wireless medium?

We are running blink node experiment now to test our boards. We have 2 nodes, one AP and one STA, and a PC which are connected to a common gigabit switch. When we run the python code on the PC, the LEDs on both AP and STA start blinking but I am not sure that station get the command from AP via wireless medium or the ethernet. So how could I make sure that AP and STA are exchanging packets via wireless medium?

Re: How to make sure WARP nodes sending packets via wireless medium?

Commands from wlan_exp (Python) are never sent over-the-air. By default wlan_exp connects to the WARP v3 node on the node's ETH B interface.

The AP and STA designs bridge the ETH A interfaces to the wireless medium. A common configuration is to connect the AP ETH A interface to an Ethernet network that is connected to the internet (has a DHCP server and router), then connect the STA ETH A interface directly to a PC. The PC will send packets via its wired interface; these will be encapsulated by the STA design, transmitted wirelessly, received by the AP, and bridged to the AP ETH A interface.
