Connecting Realsense L515 in Network

[TheNemo05]

|---------------------------------|------------------------------------------- |
| Camera Model | L515 |
| Firmware Version | 01.05.08.01 |
| Operating System & Version | Ubuntu 20, Debian 11 |
| Kernel Version (Linux Only) | for ubuntu (Linux 5.14.0-1054-oem x86_64), for debian (Linux 5.15.76-v8+ aarch64)|
| Platform | PC & Raspberry Pi |
| SDK Version | v2.51.1 |
| Language | Python |

Issue Description

As mentioned in system parameters 2 systems are being used, Ubuntu installed in PC & Debian based system used in Raspberry pI Model 4. Both the systems has Realsense SDK viewer version 2.51.1. Realsense L515 lidar is connected to Raspberry Pi using USB type C connection. Raspberry pi is connected to PC using SSh command.

The IP 10.42.0.176 is Raspberry Pi's IP.
As per the process shown in https://dev.intelrealsense.com/docs/open-source-ethernet-networking-for-intel-realsense-depth-cameras the Realsense SDK should display the camera connected in Network using the Add network device.


After inserting the IP of Raspberry pi, an error is displayed stating '[getStreams] error: Connection to server failed: Connection refused - -107'
Is there anything missing, Thanks in advance for support.

@MartyG-RealSense can u please look into this.

[MartyG-RealSense]

Hi @TheNemo05 Can you confirm please whether you have built the librealsense SDK on the Pi 4 from source code with CMake and included -DBUILD_NETWORK_DEVICE=ON in the CMake build instruction so that the SDK is built with networking support and installs the rs-server networking tool on the Pi? Doing this is necessary in order to be able to make a network connection from the RealSense Viewer to the camera.

i ve included the -DBUILD_NETWORK_DEVICE=ON in CMake file, i ve not found any document to install rs-server. can u help me with it please.

[MartyG-RealSense]

rs-server should be compiled automatically when the SDK is built if ** -DBUILD_NETWORK_DEVICE=ON** is included in the CMake build instruction on the Pi. For example:

cmake ../ -DCMAKE_BUILD_TYPE=RELEASE -DBUILD_NETWORK_DEVICE=ON

However, a RealSense team member advises at IntelRealSense/realsense-ros#1804 (comment) that the L515 camera model is not supported by rs-server. As the L515 model is now End of Life (retired), support would not be added to rs-server at a future date.

There is an alternate RealSense ethernet networking system for Python called EtherSense, which was the predecessor of rs-server, though I cannot guarantee that it will work with L515 due to EtherSense's age.

After cloning the repository & running this command 'sudo python setup.py' from librealsense directory, an error message is displayed 'python: can't open file 'setup.py': [Errno 2] No such file or directory'

[MartyG-RealSense]

The EtherSense project is also hosted on its developer's own GitHub. Do you experience the same problem if you clone that repo, please?
