3 days ago Hello, we've recently added debug mode which will help us identify any issues by printing error messages. Could you please download the updated version and run it again? This way, we can see exactly where the problem lies.

3 days ago The Output is as follows:
debug: true SDK Version: 2.0.1 No adapter found Init failed: 1
C:\Programming\csharp_sdk-master\bin\Debug\net8.0\csharp_sdk.exe (process 34556) exited with code 1.
The thing is, when scanning any barcode while I am in a textentry field, the code's text will get written in said textfield... So there definitely is a device connected.
On the Inateck website there is a paragraph stating, that the Firmware of certain scanners has to be updated, but only if the SN-Prefix is in a certain range.
For my case (the BCST-42) the range is: 3B09 - 3D10
As the SN of the owned scanner is 4B22[____] I haven't done anything regarding the firmware. Maybe that could be the solution?

2 days ago Hello, based on the error, it appears that your computer either lacks a Bluetooth adapter or the Bluetooth function is not turned on, as the SDK requires a Bluetooth adapter and for Bluetooth to be enabled. The current SDK does not support wired connections or connections via a dongle.

2 days ago Hello, this explains a lot. Thanks for clarifying! It works like a charm as of yet.
If you are interested, I extended the demo a bit to be able to understand better, what is happening. Maybe it helps future customers:

After changing the path to the libfile to: const string LibPath = "./lib/scanner_ble_x86_64-pc-windows-gnu.dll"; and copying the file to: "C:\Programming\csharp_sdk-master\bin\x64\Debug\net8.0\lib\scanner_ble_x86_64-pc-windows-gnu.dll"
running the project results in this output:

The Scanner used is: Model: BCST-42 SN: 4B22XXL1
The Scanner is connected via the Dongle. I've tried disconnecting the dongle and connecting using a cable. The results are the same.
The OS is: OS Name: Microsoft WIndows 10 Enterprise Version: 10.0.19045 Build 19045 System Type: x64-based PC
I hope I provided all needed Information...
