As the title suggests, I would like to analyze the bluetooth traffic of my android device on wireshark, I was able to do that just a few hours ago by just connecting the Android device via usb and opening up wireshark, the android bluetooth interface would just shouw up and worked perfectly, after some time (I rebooted the phone and did a couple other things), the bluetooth interface was gone. I'm now able to only access the phone Logcat.
I think I disabled something, or have to do some steps in order to activate this feature, that I had activated before without knowing, but I can't seem to replicate that, and the only things I find online are about saving HCI log in a file and then analyzing them on wireshark, which is not ehat I'm looking for right now
I too was looking for a way to do this and I think the best way I've found so far is to use wireshark's androiddump tool: https://www.wireshark.org/docs/man-pages/androiddump.html
It's built in with wireshark and if your phone is plugged in with adb installed and configured correctly so that you can do an adb shell from your computer, then when you open wireshark your android's bluetooth interface should show up as possible source of capture as soon as you open wireshark.
You were probably using Wireshark extcap androiddump option which has three requirements:
rooted device
developer option Bluetooth HCI snoop enabled
adb server running
From your description, you simply opened wireshark and did not start Android server
Please do the following:
enable developer option Bluetooth HCI snoop - you can do so by
tapping your device serial number in your settings menu
From your terminal execute the following command: $adb start-server when you are finished you can use $adb kill-server

I installed the Android WiFi ADB plugin to run the app wirelessly. But it's not working it's giving error that Phone and PC should be connected on the same network. I use my phone hotspot to run the internet on my PC. Then I use another phone but then also same error. Someone says it will not work because you use the mobile hotspot for an internet connection on your PC. But when I try to connect another phone then also the same issue. But the same way my friend also does. he also uses the internet using a mobile hotspot but it's working fine on his phone. I have a POCO F1 Phone.
I'm answering this hoping this may help others as well as I find it helpful for my use.
First, Turn on ADB in your phone's developer options. You can search Your_phone_model developer options to find that.
Second, After turning on ADB, Connect your phone with data cable to your laptop/desktop.
Open a Command prompt window, Type adb tcpip 5555, Press allow in adb prompt shown in your phone, it will show restarting adb in tcpip mode. Now, disconnect the USB cable. You can use different port number to connect another device.
Type adb connect your_phone_ip:5555 as for example adb connect 192.168.43.1:5555 in case of hotspot. You can check Phone's IP in WIFI's advanced setting of your phone or in status section.
Now, Everytime your device restarts, repeat steps 3-4.
You can also make a script, just type adb connect your_phone_ip:5555 in a notepad file, save it as name.bat file, right click on it and send to desktop (create shortcut), in the settings on the shortcut, set any shortcut keys. Now, anytime you want to connect, just press the shortcut keys. That's how I do it. You can further open Android studio by this script so it will open Android Studio as well.
Remember, whenever it says Device is Offline, restarts your phone's wifi and reconnect it.
I'm using scrcpy to mirror the phone screen to computer, which uses adb.
I've followed the steps and it works:
# connect via USB
adb devices
adb tcpip 5555
# now unplug USB, and the following will work over WiFi
adb connect 192.168.1.14:5555
scrcpy
But when you reboot the phone or computer, doing adb connect 192.168.1.14:5555 and scrcpy doesn't work anymore (NB: the phone IP hasn't changed, it's fixed).
Reading the answers from Run/install/debug Android applications over Wi-Fi?, I see 3 options:
plug the USB cable each time before doing a wireless connection, but this is annoying, and somehow reduces the interest of wireless...
Use "ADB over network" (main answer's screenshot), but as noted by many people in comments: "i do not have the "ADB over network" option in debugging option"; so this option doesn't work for me
other techniques that need root (not possible for me)
Question: how to pair the phone and computer with a USB cable only once, and then be able to use adb between them without having to use a USB connection first, after each reboot?
Note: I don't use Android Studio, but only scrcpy.
It's not possible without root the phone. If your phone has rooted. You can use this app. https://play.google.com/store/apps/details?id=com.ttxapps.wifiadb&hl=en. With this app you can easily debugs android apps with only wifi. Don't want USB cable even only first time.
Based on all the information I have the next conclusion. Just for reference, how a low-level setup with changing add routes works inside, described here. It comes up, there is a pretty straight thing inside changing navigation with adb tcpip <port>.
The first thing we need to do, it's setup system property with tcp port with name setprop service.adb.tcp.port (and values with a port number) By default, there is not such property.
And then just restart adb with few commands. stop adbd and start adbd on a device in order to debug bridge listen new port. What is the trick here, that you don't have access to this service and stop/start it without root. But it could be easily done, via Developer setting with stop/start debugging.
This few simple action hidden inside adb tcpip <port>. And the problem, that you cannot change system properties (point 1). That is why all application requires root access, it's just to change the single option. That is why, we need to connect with USB to debug bridge, which can change properties with his sepolicy.
So answering your question. I don't understand either, what is the problem or enabling this small setup in Developer options. But right now, it's possible to do so on some Roms, or devices with root access.
I recently bought chinesse device that connects via bluetooth with android phone / tablet. Since there is no application availible for windows / linux I want to create one for personal usage.
Usually phone connects to the device and exchanges some data. I connected PC to the device and looked into serial debugger and menaged to discover the protocol (one way only). Phone sends only one command to the device. But this time I'm not able to find out what it containts.
Is there any software that will allow me to look into data sent via bluetooth? I tried decompiling the app, but it looks really unfriendly.
Thanks.
Android 4.4 (Kit Kat) does have a new sniffing capability for Bluetooth. You should give it a try.
If you don’t own a sniffing device however, you aren’t necessarily out
of luck. In many cases we can obtain positive results with a new
feature introduced in Android 4.4: the ability to capture all
Bluetooth HCI packets and save them to a file.
When the Analyst has finished populating the capture file by running
the application being tested, he can pull the file generated by
Android into the external storage of the device and analyze it (with
Wireshark, for example).
Once this setting is activated, Android will save the packet capture
to /sdcard/btsnoop_hci.log to be pulled by the analyst and inspected.
Type the following in case /sdcard/ is not the right path on your particular device:
adb shell echo \$EXTERNAL_STORAGE
We can then open a shell and pull the file: $adb pull
/sdcard/btsnoop_hci.log and inspect it with Wireshark, just like a PCAP
collected by sniffing WiFi traffic for example, so it is very simple
and well supported:
[source]
You can enable this by going to Settings->Developer Options, then checking the box next to "Bluetooth HCI Snoop Log."
Also, this might help finding the actual location the btsnoop_hci.log is being saved:
adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"
On a Xiaomi phone with Android 11, after enabling "Bluetooth HCI Snoop log" in developer settings the file seems to be written to
/data/misc/bluetooth/logs/btsnoop_hci.log (only accessible with root)
/sdcard/MIUI/debug_log/common/com.android.bluetooth/btsnoop_hci.log
In addition, it's possible to get the log by running adb bugreport zipname from the computer, as written here.
Note that the logging only turned on after a reboot for me.
On Xiaomi Redmi Note 9s
This configuration file can also be found /storage/emulated/0/MIUI/debug_log/common
named as hci_snoop20210210214303.cfa hci_snoop20210211095126.cfa
With enabled 'Settings->Developer Options, then checking the box next to "Bluetooth HCI Snoop Log." '
I was used Total Commander for taking file from Internal storage
How can I capture mobile phone traffic on Wireshark?
Here are some suggestions:
For Android phones, any network: Root your phone, then install tcpdump on it. This app is a tcpdump wrapper that will install tcpdump and enable you to start captures using a GUI. Tip: You will need to make sure you supply the right interface name for the capture and this varies from one device to another, eg -i eth0 or -i tiwlan0 - or use -i any to log all interfaces
For Android 4.0+ phones: Android PCAP from Kismet uses the USB OTG interface to support packet capture without requiring root. I haven't tried this app, and there are some restrictions on the type of devices supported (see their page)
For Android phones: tPacketCapture uses the Android VPN service to intercept packets and capture them. I have used this app successfully, but it also seems to affect the performance with large traffic volumes (eg video streaming)
For IOS 5+ devices, any network: iOS 5 added a remote virtual interface (RVI) facility that lets you use Mac OS X packet trace programs to capture traces from an iOS device. See here for more details
For all phones, wi-fi only: Set up your Mac or PC as a wireless access point, then run wireshark on the computer.
For all phones, wi-fi only: Get a capture device that can sniff wi-fi. This has the advantage of giving you 802.11x headers as well, but you may miss some of the packets
Capture using a VPN server: Its fairly easy to set-up your own VPN server using OpenVPN. You can then route your traffic through your server by setting up the mobile device as a VPN client and capture the traffic on the server end.
In addition to rupello's excellent answer, a "dirty" but very effective trick:
For all phones, any (local) network: Set up your PC to Man-In-The-Middle your mobile device.
Use Ettercap to do ARP spoofing between your mobile device and your router, and all your mobile's traffic will appear in Wireshark. See this tutorial for set-up details
Another option which has not been suggested here is to run the app you want to monitor in the Android emulator from the Android SDK. You can then easily capture the traffic with wireshark on the same machine.
This was the easiest option for me.
Wireshark + OSX + iOS:
Great overview so far, but if you want specifics for Wireshark + OSX + iOS:
install Wireshark on your computer
connect iOS device to computer via USB cable
connect iOS device and computer to the same WiFi network
run this command in a OSX terminal window: rvictl -s x where x is the UDID of your iOS device. You can find the UDID of your iOS device via iTunes (make sure you are using the UDID and not the serial number).
goto Wireshark Capture->Options, a dialog box appears, click on the line rvi0 then press the Start button.
Now you will see all network traffic on the iOS device. It can be pretty overwhelming. A couple of pointers:
don't use iOS with a VPN, you don't be able to make sense of the encrypted traffic
use simple filters to focus on interesting traffic
ip.addr==204.144.14.134 views traffic with a source or destination address of 204.144.14.134
http views only http traffic
Here's a sample window depicting TCP traffic for for pdf download from 204.144.14.134:
For Android phone I used tPacketCapture:
https://play.google.com/store/apps/details?id=jp.co.taosoftware.android.packetcapture&hl=en
This app was a lifesaver I was debugging a problem with failure of SSL/TLS handshake on my Android app. Tried to setup ad hoc networking so I could use wireshark on my laptop. It did not work for me. This app quickly allowed me to capture network traffic, share it on my Google Drive so I could download on my laptop where I could examine it with Wireshark! Awesome and no root required!
Packet Capture Android app implements a VPN that logs all network traffic on the Android device. You don't need to setup any VPN/proxy server on your PC. Does not needs root. Supports SSL decryption which tPacketCapture does not. It also includes a good log viewer.
Preconditions: adb and wireshark is installed on your computer and you have a rooted android device.
Download tcpdump to ~/Downloads
adb push ~/Downloads/tcpdump /sdcard/
adb shell
su root
mv /sdcard/tcpdump /data/local/
cd /data/local/
chmod +x tcpdump
./tcpdump -vv -i any -s 0 -w /sdcard/dump.pcap
CTRL+C after you've captured enough packets.
exit
exit
adb pull /sdcard/dump.pcap ~/Downloads/
Now you can open the pcap file using Wireshark.
Install Fiddler on your PC and use it as a proxy on your Android device.

Similarly to making your PC a wireless access point, but can be much easier, is using reverse tethering. If you happen to have an HTC phone they have a nice reverse-tethering option called "Internet pass-through", under the network/mobile network sharing settings. It routes all your traffic through your PC and you can just run Wireshark there.
Make your laptop a wifi hotspot for your phone (any) and connect it to internet. Sniff Traffic on your wifi interface using wireshark.
you will get to know a lot of anti privacy stuff!
As a Wireshark alternative/companion for Android, you can try my open source app PCAPdroid. On non-rooted devices, it uses the VPNService to capture the traffic with some limitations. On rooted devices, it works like a user-friendly tcpdump.
You can analyze connections and packets payload directly into the app, or export the traffic in PCAP format to analyze it on a PC with Wireshark. It has many other cool features, give it a try!
For Android, I previously used tPacketCapture but it didn't work well for an app streaming some video. I'm now using Shark. You need to be root to use it though.
It uses TCPDump (check the arguments you can pass) and creates a pcap file that can be read by Wireshark. The default arguments are usually good enough for me.
I had a similar problem that inspired me to develop an app that could help to capture traffic from an Android device. The app features SSH server that allows you to have traffic in Wireshark on the fly (sshdump wireshark component). As the app uses an OS feature called VPNService to capture traffic, it does not require the root access.
The app is in early Beta. If you have any issues/suggestions, do not hesitate to let me know.

For iOS Devices:
⦿ Open Terminal and simply write:
rvictl -s udid
it'll open an interface on Wireshark with a name, In my case its rvi0.
udid is iPhone's unique device id.

Can I dump logs from an android phone over wifi (using tcp/ip) using adb? adb connect can be used, but it needs some server to be running on the phone (at 5555 port). How do I start this server?
Or the only way to get logs from a phone is by connecting it as a USB device?
Install adbWireless on your phone. Run the application and click on the big button (you cannot miss it!). It will activate ADB over Wifi and display the URL to use to connect to it with the adb command.
On your computer, run the adb command with the connect parameter. The usage for adb says:
connect <host>[:<port>] - connect to a device via TCP/IP
Port 5555 is used by default if no port number is specified.
Obviously the computer and the smartphone must be on the same Wifi network.

All you are trying to do is drop adb logcat command on the device & send output stream to a remote location. I would suggest, read this post about how to run shell commands in your app.
The summary is
Run "adb logcat"
Collect Output Stream of the command in a file on device
& Finally post that file to your local server OR Manually pull that file from device
The post contains link to everything you are looking for.
Android is very paranoid when it comes to network access. Without root access, you can't really run any servers, just clients. In short, without root, look at the answer from 100rabh.
If you do have root, you could either open up your network stack for incoming connections on port 5555, or you could hack adb to do the inverse connection (that is, connect to your client). The latter is way more secure and shouldn't really be to hard to do. (I haven't looked at the code for a while, though.) The communication bits for all parts of adb is handled in one and the same library, for all three parts of adb (server, daemon and client).
By the way, what you refer to as a server on the phone is really the adb daemon.
