Release Notes
Connect to remote cortex
This feature is only available since 2.7.1 release.
Following steps are the guideline to use the remote tool to work with Cortex running on Raspberry Pi 4
Install Cortex on Pi
To install Cortex on Pi :
- ssh to Pi
- Download the file emotivapps_2.7.1.beta_armhf.deb
- Run the following command to install
1
$ sudo apt-get install ./emotivapps_2.7.1.beta_armhf.deb
Copied!
After installing, you can check if
cortex service is running with command1
$ sudo systemctl status cortex
Copied!
Remote connect to Cortex running on Pi
- ssh to Pi and change directory to /usr/local/emotivapps/bin
1
$ cd /usr/local/emotivapps/bin
Copied!
- Run following command to allow access from remote IP. More usage of
cortexaccesstool can be found here.
1
# cortexaccess ip accept ip_address_of_machine_which_does_remote_to_pi
2
# for example:
3
$ ./cortexaccess ip accept 192.168.1.11
Copied!
- After allowing access, run the following command to confirm
1
$ ./cortexaccess ip list
Copied!
- Find the IP address of your Pi device with command ifconfig, for example 192.168.1.21. Note that only IP addresses in a specific range are supported, otherwise you have to configure
hostsfile and useemotiv-cortex.remoteDNS. See the range of supported IP addresses and how to configure hosts files. - Put the above IP address (or
emotiv-cortex.remoteif the IP address is not supported) into the text box under the Remote Connect session - Then click Connect
Connect headset
After Cortex is running on Pi and EMOTIVApp remotes to Pi successfully, user can connect a headset to Pi with Dongle or Bluetooth connection. Headsets will be showed up on the Devices tab.
Note with bluetooth connection, in case the headset connection is lost unexpectedly (even the headset is turned on), there may be an issue with
bluetooth service, you should make sure this bluetooth service is running stable. Most of the time, you can troubleshoot by restarting bluetooth service first, then cortex service, using the following commands on Pi:1
$ sudo systemctl restart bluetooth
2
$ sudo systemctl restart cortex
Copied!
Develop a remote application
In order to connect with Cortex running on Pi and develop an application, user must change url to Pi's IP address.
For example with python example, user should have following change in file
1
def __init__(self, user, debug_mode=False):
2
url = "wss://ip_address_of_PI:6868"
Copied!
