Connect Bluetooth Dongle (CSR 4.0) with Arduino Bluetooth Module ("BT05")

Projects Networking, Protocols, and Devices

Hello,

I bought a Bluetooth Dongle (BT 4.0; CSR 4.0; Bluetooth 4.0 USB Stick BT Adapter Mini Nano Dongle EDR High Speed Dual-mode AUX online kaufen | eBay) for my PC and a Bluetooth Module for my Arduino.
And now my problem: If I try to connect the dongle with the module I get this error: "Connection failed because wrong code was entered"! OK, I know that I have to enter a code but it doesn't ask me for that. If I try to connect it it shows me almost instantly that error.

Thanks in advance,

but it doesn't ask me for that.

What doesn't? The elephant in the pink tutu?

The program does not ask me to enter the code.
Here is a screenshot of the error: https://drive.google.com/open?id=0B5Jav5xBGQ2lMm1pUWNRZHFxN28
I use the driver that was delivered with the dongle.

Well, at least "the program" isn't a useless pronoun with no referent (and isn't an elephant in a pink tutu (how they got that guy into it, I can't imagine)).

But, still no clue what "the program" is.

Pretend that we can't see what you see. Because we can't. Explain what you are doing. Explain which device (the dongle or the one connected to the Arduino) is supposed to supply/require a code.

And, no, I can't see what you posted on google drive. Paranoid employer (with good reason, with employees like me).

Okay, step by step:

  1. I open the explorer and click on "Bluetooth Devices" under "Devices and Drives".
  2. I click on "Add Device" in the top left corner and then on "All".
  3. I choose my Bluetooth Module ("BT05") and the computer/Bluetooth dongle trys to connect to it.
  4. The error message shows up.

Sorry if my English is not perfect because I'm German...
I hope that was better now. If you want I can record that on video and upload it to YouTube.

Thanks,

Much better. Thank you.

One final question. Is there code running on the Arduino?

No. For the start I just wanted to connect the module to the PC.
That means I only connected GND and VCC of the module.
The red LED of the module is blinking. I know that it means it isn't connected.
Did I something wrong? I tried it also with code but the result is the same (I connected RX (Pin 10) -> TXD; TX (Pin 11) -> RXD and used SoftwareSerial).

No idea what the problem is?
