In the last weeks I experimented with my Raspberry Pi B and with the PiCamera. I had the idea to establish a connection between the RasPi and an Android device or (if it is easier) to a windows notebook without an access point in between, just like the GoPro camera and its App. I would like to have a live stream from the PiCamera to the other device and the possibility to start/stop recording a video or simply take a picture.
The app itself is not my problem, I wrote some simple apps before. But I didn't yet find a tutorial or description how to set up the communication and the stream.
I bought a WiFi dongle (Fritz!WLAN Stick N - by AVM) that supports WiFi direct and my phone (Samsung Galaxy S5 mini) does as well.
My first question is how to set up this stick on Raspbian - yet it is not recognises as a wifi dongle, and the second is how to achieve what I descriebed above.
Could anyone please describe what I can do?
Thanks in advance!
PS: I prefer a description for bash because I use SSH

I'm a bit confused. I explain to you my project, I would like to make a "reader" by using beacon technology (ibeacon for apple, eddystone for android) using a raspberry pi 3. The smatphone application sends an acknowledgment code when passing the person. The raspberry marks and updates an online database. I wanted to ask, first of all can this be done? My problem is to realize the beacon transmission, then for the app and the database I have no problems. I tried using bluez but I can not detect the phone. Is there any online tutorial that could help me? Thanks
If you are looking to use the phone to emit a beacon transmission and then use the Raspberry Pi 3 to detect the beacon, then yes, this is possible. I put together a tutorial on how to use the Android Things to detect beacons on the Raspberry Pi 3.
The problem with using BlueZ for beacon detection is that it is simply not stable on the Raspberry Pi, and will freeze up and stop detecting requiring a reboot.
Recently I have installed fluxion on my Pi 2. There wasn't any problem in the installation process, but when I tried to use fluxion, (after choosing the language) I got the message no wireless cards found ....
It is strange because I was able to see wlan0 (and also connect to the internet) before I had selected language. And also the light on my Wi-Fi dongle goes off.
Is there any solution to fix this problem?
Finally, I could solve the problem. I bought a new wireless usb adapter. For those who are curious I will introduce model of the device. I purchased TP-Link TL-WN722N which is suitable for hacking tools in raspberry pi. It also supports monitor mode. For more information you can visit the official website.
Hello I am trying to work out how to set kodi up on my smart TV. My main problem lies with the TV being on the wall in another room too far away from power sources. She has sky installed and that was situated in the other room and with a HDMI lead fed under to floorboards to the other room by a professional someone or other. I am unable to feed another HDMI lead along the line.
Is there a way I could connect kodi by some other means to the TV? I am not really up on these things.
At the moment I have the kodi box in another room and I have to switch the sky lead to the kodi box to use. Also this means you have to be in the other room.
Can anyone suggest a way for me to get kodi working on the tv and be able to operate it via remote control?
I use Kodi on all of my TVs through an amazon fire stick. Most smart TVs have a USB on the back of the TV that can power the fire stick while its plugged into the HDMI so you wouldn't have to worry about power. I have a Sony bravia that will control the fire stick as long as I am on the input the fire stick is plugged into so no need for an additional remote.
To start off this is the wrong place to ask. This is a Q and A platform for programming questions and coding related questions.
To give you an answer though because I'm not a dick the best way to do it would be using a NAS. You would have two Kodi boxes but one media store.
I'm not sure which device do you use.
In my case, I installed Kodi on my Raspberry Pi(RPi) and TV and RPi are connected with HDMI. My TV is Samsung SmartTV, which supports HDMI-CEC. So, RPI can get RCU Key input from TV.
(HDMI-CEC allows devices connected to your TV through HDMI ports to communicate back and forth with your TV. )
In addition, you can customize keymaps for remotes in GUI by using the community Keymap Editor add-on.

Check your TV supports HDMI-CEC, first.
I have an android app that outputs sound normally on a phone. I also put it into an android device and can hear audio on tv through HDMI cable. I also have an android things app that moves a servo and can put audio on the tv, also working as expected.
What I can't do is get audio from the audio jack, which would be my preferred option since I want something without a display.
I have lots of logcat entries saying everything is normal and sound is not failing, but other than that I can't rule out if it's an OS capability that's turned off (there's no mention in release notes), something that needs to be tuned into config.txt, whether I need extra lines of code, or it is muted.
I'm assuming audio is not getting to the jack at all. I know that the Raspberry pi 3 b audio jack also carries video, and I've tried to tap into every combination of its pins without success, both using a cable splitter and putting cables on the pins of the connector directly on the board. I'm also assuming that one of the exposed pins under the board carries audio only. Though I'd be grateful if someone could clarify which has left / right channel, even if tested on Raspbian or other OSs.
As seen in following logs, audio focus is ok and SoundPool.play never return 0 (as showin in line that says RESULT === 8):

As pointed in the Raspberry Pi overlay documentation
2) The onboard analogue audio output uses both PWM channel
So you can't use PWM to drive a servo and play sounds thru the onboard Audio simultaneously.
A few options are possible:
try the USB audio support announced in Developer Preview 2
file a feature request to add support for I2S in the Peripheral IO API.
I had the same issue sending audio to AUX port while the HDMI port is connected just for video output.
But, the solution that worked for me is, I first deployed my AndroidThings app onto RasPi and connected AUX port to test the audio, then I connected the HDMI to test the video out. In this sequence, everything worked both audio from AUX port and Video from HDMI.
I have a RPI 2 with Windows 10 IoT Preview installed on it, and I'm trying to create a Windows Universal App that displays a live feed from the Raspberry Pi camera (specifically the Pi NoIR camera). Is this possible?
It's not possible yet. There are no Windows drivers available for the camera. This is likely to change at some point, but your only current option is to use a different OS.
Goobering is correct. Drivers for USB WebCam type devices are likely to be available in the next drop of the OS. I'm uncertain about the RPi camera.
