Simplified version for begginers ?

[Yu-b]

Hi ! I've been able to connect my ble device with your software. I m trying to interact with my device directly through the console terminal with noble, but I ve not been able to succeed so far ...

Could you please provide the minimal code necessary to recognize ble devices and establish connection ?

That would help me a lot !!!

It is great to have example code to start with. I too am new to a lot of this and am racing to try to learn the various types of languages and interfaces. I have been able to do a fair amount with the bluefruit via the arduino ide, and am familiar with visual studio, but have never used node.js.

I installed and followed all the instructions, however I get a ton of errors when I run npm install in the soruce directory. The error says it fails on "node-gyp rebuild" Below is the output when trying npm install.

After I can at least get it to compile and run on windows 10, I will start looking at the code to see if I can update it to my needs. What I really want is just a simple UART interface, of which I'm most familiar with Visual Studio C++ / C# and have been able to do arduino interface programs via the serial port.

Thanks for any help you can provide,
