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.

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've been using node-red to simulate TCP and RTU slaves on a raspberry pi and a dell gateway. So far, I've managed to get the TCP slave working, but it doesn't seem possible to do it via rs485 on node-red.
Is it possible to use pymodbus running on a raspberry pi connected to a dell gateway via rs485 to simulate a slave device, because the examples provided only specify a serial connection rather than an rs485 connection specifically? If it is possible, please could you recommend an example that I should use from the pymodbus readthedocs examples?
I am trying to establish a serial connection between the RPI3 and an Arduino. Because that wasn't working I connected a USB to TTY cable from my laptop to the Rx/Tx pins of RPI. I was eventually able to use PuTTy to connect to it.
I am running Android Things on the RPI and the android code I have running is supposed to be a loopback (reading from UART and writing back what was read).
Here is where I am confused....
When PuTTy connected I was presented with a command line console on the RPI.
How do I get the Rx/Tx pins on the RPI to just be serial connections into and from my application and NOT a way to log into the console?
Is that a bad idea? I suppose if I ever needed to log into the RPI this would make it more difficult...
I figured out what I was doing wrong...
When following the setup directions at the below site I was using the Bluetooth mode instead of the Application mode. When I followed the directions for Application mode I was able to start using UART0 for serial comms
Set the console attribute to the following in cmdline.txt:
console=tty0
Add the following line in config.txt:
dtoverlay=pi3-disable-bt
Remove the following lines from config.txt:
enabled_uart=1
core_freq=400

Beginning with Developer Preview 3, in which USB-Serial devices support added, You can use external USB-UART dongles like this instead of UART of Raspberry Pi 3.
As part of my project requirement I want to make a system which will detect all the WiFi devices in my router range either its connected or not, I did some research on it then I found something like wireshark ,kismate etc I just tried the wireshark by making my Mac machine's WiFi as an adhoc network and its all fine I am able to list all the WiFi devices in wireshark, now I want to make a real-time system based on a real WiFi router I don't know how I will configure my router using my PC and how I will monitor the router from my PC , one more thing if I am using this wireshark how I will use this data for my requirement. If any one worked with similar scenarios please help me..thanks in advance
To do that you will need more than the usual API that you have on commercial WiFi routers (by that I mean a full SSH access). I would:
flash my router with OpenWRT (you can search for your router on this page for detailed instructions)
Install the aircrack-ng suite on the flashed router with
opkg update
opkg install aircrack-ng
Put my WiFi card in monitor mode and run the airodump service:
airmon-ng start wlan0 #Put your NIC in monitor mode
airodump-ng mon0 #Sniff surrounding packets
You don't necessarily have to install aircrack-ng, you can just put your card in monitor mode using command line (look at the documentation for your WiFi driver) and then run tcpdump (command line equivalent to wireshark) but aircrack works very well and has a nice format.
Also, I should warn you that you can brick your router by flashing it. I never had such a problem when flashing router mentioned on the OpenWRT wiki and there are (most of the times) ways to restore a bricked router depending on the brand but I am not responsible if you break it ;)
Im acquiring data from a sensor using RaspberryPi. Now the idea is to get the data streaming over an ethernet link to my Windows 7 laptop and do the monitoring and recording on the laptop. Can I get some advice on how to implement this in C/C++.
The idea is to get the signal from a sensor streamed to a Windows GUI.
You can push data from your raspberry PI to you Windows
You can have some sort of service on your Windows box and your raspberry PI can push information to your software running on your Windows.
or
you can pull data from your raspberry PI to you Windows
In this case, raspberry PI would be a passive provider and Windows would ask for data.
Hard to give you more information without more details but basically you decide who is going to the passive and active and program that way.
I personally would request data from the raspberry PI to Windows as I can have my service running and just update when I need instead of having my service running and suddenly have my data changing.
That said, it's hard to say without more details.
You need to tell what kind of programming language are you going to use.
According to your question, you need to dig into socket programming.
Recently,I linked my two Raspberry-Pi by writing a python script to establish a TCP connection between them.
and there is this protocol called "RTSP(Real Time Streaming Protocol)" to (as the name says) stream data in real-time.
(If you are to use python , there is this module called gst-python for streaming).
I think the above infos would give you where to start.
