Title: Using Bluetooth LE: Howto ? Components
Post by: JP-CASSOU on June 27, 2022, 03:12:32 pm

Hello,

I want to communicate with a Bluetooth LE device.

I can't find any detailed example in FreePascal, either on Windows or Linux

I am looking for DETAILED code examples.

Thanks

Hi,

You need check which kind of device are dectect. For example  some bluethoot devices (in windows) are a serial port. So you should use a serial port component like LazSerial.

With no more info about the device is  complicate.

My device BT LE uses GATT protocol. TLazSerial unusable here

A fast search in google, gives some pages that sells Delphi packages.

But I found a C library https://github.com/labapart/gattlib (https://github.com/labapart/gattlib). You can take a look, compile it, and access to the library from Free Pascal.

I'm newbie in C. Exists FPC translation of the headers ?
