Hi Klaus (bist du auch deutscher? ),
thank you very much for answering.
I have to connect to the RN4871U-V module, because I want to build a Lightgun for the PC.
For that Lightgun I want to use a modified Airsoft Gun with a Mosfet Board inside.
This mosfet Board has optical sensors on it, so every time the trigger is pressed or the selector plate of the gun is moved, these sensors will register it.
On the Board itself is a BLE chip to connect to a smartphone app for changing things.
I talked to the development department of that company, and they told me, that on the Mosfet board I want to buy, the RN4871U-V module is used.
With the android App "Serial Bluetooth Terminal", I can connect to this Board and see the Sensor Data in real-time.
This is the board:
The DFR Beetle would be the perfect fit size wise, because it's tiny, and I would have enough room to store it in the Airsoft.
After that, the sensor data from the mosfet board have to go to a device like the beetle.
Then there is a second arduino I'm using for this project.
On this one there is already an IR camera mounted and a software installed. This software translates the IR camera movements into mouse coordinates. The software is called "Gun4IR".
On the arduino with the "gun4ir" software on it, you can solder cables to the pins. One Pin is for the trigger, the others are for various Buttons you can connect.
I thought that I could connect the Beetle Pins to that "gun4ir" Arduino.
So every time the optical sensors of the mosfet board registers a specific movement, the Beetle gets that Info via Bluetooth and send it directly to the other Arduino with a wired connection. *in theory
Well, I thought at first I have to know what Hardware I can use for that job.
