I have setup a Raspberry Pi and a cameramodule, the Streaming Server UV4L works fine, I have a nice picture over a WebRTC stream.
Now I wanted to use an IP camera (RTSP) as input for the UV4L server, how can that be done?

I'm trying to use Sparkfun's OBD-II-UART board to interface with a CAN network using a Raspberry pi 4. Upon connecting to sudo screen /dev/ttyAMA0 and when I send the commands, I'm not able to get any response from the OBD-II-UART board. Can anyone suggest why it is not communicating?
I wanna catch probe requests of mobile devices that are not connected to a network using monitor mode on Raspberry pi 3. I am using Raspbian OS. I used "Wifite" command but it only shows the mac addresses of access points and not of the non connected mobile device. I am a beginner in networking and Raspberry pi. Kindly guide me which commands should I use for this purpose?
You might try looking into sniff-probes.
It switches WiFi channels every two seconds and captures incoming packets using tcpdump.
how do i connect my raspberry pi to WIFI without ethernet cable. I have a wifi dongle or usb connected to my pi but the internet still doesnt work unless i connect a ethernet canble. can someone please help me out
You can setup your wi-fi via the command line, see a detailed guide on the official site:

Another option is to use the PIXEL desktop:

I am able to send data from sensor to server using Raspberry Pi, but my aim is to find the devices (for example a sensor) connected to the Raspberry Pi using any language.
I have a task to connect PROFIBUS (field bus technology by Siemens) to my Raspberry Pi. I need to make my Raspberry pi as a master and others devices as a slaves.
Let me know if you have any idea about how to make this connection. I am totally new in this topic and have no idea about this.
You might have a look at this project: https://bues.ch/cms/automation/profibus
When I understand it correctly, Profibus (Modbus) ist implemented by RS-485, that is not directly supported by the Raspberry Pi GPIOs.
You have to buy an extra shield or an USB to RS-485 Adapter.
There is also a library to send/receive data using modbus-protocol:
