I have plugged in a RFID scanner into the usb port of the raspberry pi. I noticed it appears in the /dev/input/by-id folder as usb-RFIDeas_USB_Keyboard-event-kbd.
I found code on GitHub that seems to suggest that I can read from this device, but I am pretty new to understanding all of this so I keep getting confused about how I can run the code to read information from my RFID scanner.

I'm using temperature Sensor in my project which supports BLE, first I checked this sensor with android mobile with BeaconSet+ app it worked fine, later I tried to connect with Raspberry Pi it got connected, but problem is I can't able to read characteristic data from sensor, but I'm able to read it in android mobile, so I tried to capture and compare two packets the difference I noted is Bluetooth packet from raspberry Pi only contains handle it does not contain UUID but packets from Bluetooth Packet from Android contains both handle and UUID, is this the reason that I'm not getting my data with Raspberrry Pi.
Tools I used are gatttool and bluetoothctl and version of bluez is 5.55.
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.
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 am thinking of starting a project where I use the NXP Explore-NFC board for the Raspberry Pi so that I can write NDEF messages to the NFC via an Android device. I currently own the Raspberry Pi and the NXP Explore-NFC board. I have been doing some research and know that you can use the libnfc library with the board. My background is in Java and Android development, so I have very little experience in embedded systems. This is why I wanted to use the libnfc library.
I wanted to know if anyone has managed to get this working with the same NFC board and if so, do I need to learn any new programming languages to achieve this. If anyone has any information about this please let me know. Thank you in advance.
I have set up Ibeacon raspberry pi
it is detecting bluetooths
root#raspberrypi:~# hcitool scan
Scanning ...

Now I want it to broadcast messages
How can I do that
You can make an iBeacon out of a Raspberry Pi using this tutorial. My company also sells all the parts you need as iBeacon Development Kits that have this pre-assembled with the necessary software. If you want, we can also send you just the SD card so you can use the Raspberry Pi you already have.
If you want a utility to do more advanced iBeacon detection on the Raspberry Pi, check out this answer. We are still working out some of the kinks, but we will eventually release it with the iBeacon Development Kit as well.
