WiFi Direct Everyone knows about WiFi, but few people have heard of WiFi Direct. It consumes much less power than WiFi, and a lot less than cellular technologies, but still significantly more than technologies such as Bluetooth Low-Energy or Zigbee. I am looking forward for your interest and offer. Because of the relatively short operating range, Bluetooth is fairly low power. So we'll need Ball ID, Variable/Function to Object - as example changing LED color, Variable/Function to Station - as example to play a movie. To make optimal use of these tools, see the extensive list of developer tutorials and resources to support your application development with Digi XBee modules. if the object is detected, it must be identified and a function or variable must be send to object & station (for following action which will be programmed by us) The Digi XBee ecosystem includes excellent tools to support rapid wireless design, prototyping, development and deployment. the distance detection doesnt have to be extremly precise, i would say +/- 1 meter would be ok. as example: station 1 detects the object from 2 meters, station 2 detects the object from 5 meters
for each station the distance detection must be set individually (can be done manually in code - no problem). PS: this are my ideas of realisation, if you propose some else - we are open mindend.Ģ.) Programming: Variable Distance Detection, Object Identification, Variable/Function to Object & Station The Bluetooth branding covers several rather different protocols. The Bluetooth standard is developed and administered by the Bluetooth Special Interest Group (SIG), which coordinates interoperability between device manufacturers. (probabley a decision between Bluetooth BLE & XBEE) Like Wi-Fi and Zigbee, it operates in the 2.4GHz frequency range, which is license-free globally. In short form, the object is moving, the object must be detectedīy distance (RSSI) and there must be a communication betweenġ.)

Bluetooth for serial port based (UART) communications is much more expensive and less flexible. Bluetooth, Wi-Fi, Zigbee, Thread, Z-Wave and Sub-GHz RF ICs, modules and software.
The XBee series 1 is intended for non-ZigBee applications, these being more common in small projects, as compared to XBee series 2. The main components are Arduino and Bluetooth BLE or Wifi(xbee) You also have the option of ZigBee mesh routing if you need it. I am doing Prototypes for a hopefully bigger following production.
