By default, the device that collects csi is running under Linux and has already installed csi-tool.
The bash shell required to run the scripting is installed by default on linux systems, and we also need to install expect for interactive communication.
For example, in debian we can install expect in terminal using the command below:
apt-get install expect
As the codes contains configuration information for the devices, we need to modify some of the codes before running the script. We also need to create folders in the devices where we can save the csi files.
In the hmb pro (used for collecting csi), we need to create two folders: one for saving csi files which are generated from csi-tool, the other one for saving csi files which have been transfered.
mkdir file_path # folder for saving csi files, e.g. /home/debian/Desktop/data_files
sudo chmod 777 file_path
mkdir file_sent_path # folder for saving csi files which have been transfered, e.g. /home/debian/Desktop/data_files_sent
sudo chmod 777 file_sent_path
For the receiver to which we want to transfer the csi files, we also need to create a folder for receiving csi files.
mkdir file_received_path
sudo chmod 777 file_received_path
Row 2: Change "/home/debian/" to be the absolute path of the folder linux-80211n-csitool-supplementary. The double inverted commas "" need to be retained.
Row 3: Change "password" to be the password of user. The double inverted commas "" need to be retained.
Row 5: The time after timeout is the time you want to stop the collection, you can change it to any value you want to set.
Row 2 & 4: Change the ip address to be the ip of hmb pro
Row 3: Change "username" to be the username of the receiver to which we want to transfer the csi files. The double inverted commas "" need to be retained.
Row 5: Change "password" to be the password of user. The double inverted commas "" need to be retained.
Row 6: Change "ip addr" to be the ip of the receiver. The double inverted commas "" need to be retained.
Row 7: Change the path after "scp" to be file_path (create in Folders need to create); and change the path after "$user@$add:" to be file_received_path (create in Folders need to create).
Row 3: data_path=file_path
Row 15: Change the path after {filename} to be file_sent_path (create in Folders need to create).
Step 1: In hmb pro, run csi-tool initialization command before data collection. Then open two terminals and enter into root mode.
Step 2: In laptop, after connecting to AP and setting up the ip configration, open a terminal and enter into root mode and start running ping command to keep sending packages hmb pro (just set parameter -i)
Step 3: In hmb pro, first run bash transfer.sh command in one terminal and then run bash receiver.sh command in the other terminal.
Step 4: Press Ctrl+Z to stop collectting csi or set timeout in the commands before running them.
Note: collect.exp, receiver.sh, te.ss, trans.exp, transfer.sh should place in the same folder in hmb pro.
