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

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

}}}


`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 .
}}}
