Turn off the nodes:

omf tell -a offh -t mob4-1
omf tell -a offh -t mob4-2

Load the nodes with images:

omf load -i abhiadhikari-node-mob4-3.sb1.cosmos-lab.org-2023-10-27-21-13-48.ndz -t mob4-2
omf load -i abhiadhikari-node-mob4-2.sb1.cosmos-lab.org-2023-10-27-20-40-46.ndz -t mob4-1

New images (Jan 3):

omf load -i abhiadhikari-node-mob4-2.sb1.cosmos-lab.org-2024-01-03-21-04-03.ndz -t mob4-2
omf load -i abhiadhikari-node-mob4-1.sb1.cosmos-lab.org-2024-01-03-21-12-31.ndz -t mob4-1

New images (Feb 13):

omf load -i abhiadhikari-node-mob4-2.sb1.cosmos-lab.org-2024-02-14-01-47-04.ndz -t mob4-2
omf load -i abhiadhikari-node-mob4-1.sb1.cosmos-lab.org-2024-02-14-01-46-05.ndz -t mob4-1

New images (Feb 14):

omf load -i abhiadhikari-node-mob4-2.sb1.cosmos-lab.org-2024-02-14-09-05-28.ndz -t mob4-2
omf load -i abhiadhikari-node-mob4-1.sb1.cosmos-lab.org-2024-02-14-09-04-40.ndz -t mob4-1

New images (Feb 18) same image for both nodes:

omf load -i abhiadhikari-node-mob4-1.sb1.cosmos-lab.org-2024-02-18-17-27-10.ndz -t mob4-1 -r 0
omf load -i abhiadhikari-node-mob4-1.sb1.cosmos-lab.org-2024-02-18-17-27-10.ndz -t mob4-2 -r 0

mob4-1 is the transmitter, and mob4-2 is the receiver.

Turn on the nodes:

omf tell -a on -t mob4-1
omf tell -a on -t mob4-2

Within the console, make sure the PAAMs are activated properly:

mob4-1:

curl "http://rfdev-mob4-1.sb1.cosmos-lab.org:3000/array_mgmt/connect?dev_name=Local&ics=all&num_elements=16&txrx=tx&pol=h&theta=0&phi=0"
curl "http://rfdev-mob4-1.sb1.cosmos-lab.org:3000/array_mgmt/enable?dev_name=Local&ics=all&num_elements=16&txrx=tx&pol=h&theta=0&phi=0"
curl "http://rfdev-mob4-1.sb1.cosmos-lab.org:3000/array_mgmt/steer?dev_name=Local&theta=0&phi=0"

mob4-2:

curl "http://rfdev-mob4-2.sb1.cosmos-lab.org:3000/array_mgmt/connect?dev_name=Local&ics=all&num_elements=16&txrx=rx&pol=h&theta=0&phi=0"
curl "http://rfdev-mob4-2.sb1.cosmos-lab.org:3000/array_mgmt/enable?dev_name=Local&ics=all&num_elements=16&txrx=rx&pol=h&theta=0&phi=0"
curl "http://rfdev-mob4-2.sb1.cosmos-lab.org:3000/array_mgmt/steer?dev_name=Local&theta=0&phi=0"

Now create two terminals. Terminal 1 will be used for mob4-1. Terminal 2 will be used for mob4-2.

Within Terminal 1, run:

ssh -Y root@mob4-1
gnuradio-companion

Within Terminal 2, run:

ssh -Y root@mob4-2
gnuradio-companion

Run /root/tx.grc and /root/rx.grc in Terminal 1 and Terminal 2, respectively. Obtain the frequency plot shown below.

Now, we will run the beam-steering scripts being used for the NRDZ project.

Make sure to start the receiver first!

In Terminal 2, run:

root@mob4-2:~/rest# ./rx-rest.py

In Terminal 1, run:

root@mob4-1:~/rest# ./tx-rest.py

Within tx-rest.py and rx-rest.py, make sure you indicate the correct rfdev corresponding to the mobile node being used.

Exit the node and copy the data from mob4-2 to your console:

scp root@mob4-2:/mnt/test.bin .

Exit the console and copy the data from the SB1 console to your local computer:

scp abhiadhikari@sb1.cosmos-lab.org:/home/abhiadhikari/test.bin .
