I'm new to using the C Pico SDK and Bluetooth as well, but I want to get started by creating an executable on the Raspberry Pi Pico (server) and one for a client (laptop) that will send data to the server after connection. My Pico has a HC-05 BT module, so it's only capable of BT classic. I'm already familiar with connecting and flashing the Pico via USB, but I'm having trouble figuring out how to format my CMakeLists.txt properly. Upon building the project, I'm constantly getting a "Can't find btstack_config.h" error even though I cloned pico-sdk, pico-examples, etc.
Can someone please point me to example files on https://github.com/raspberrypi/pico-examples/tree/master/pico_w/bt that would be useful for my use case and maybe also provide a CMakeLists.txt that will work? Or provide a simple server.c and CMakeLists.txt that would work. Sorry, but the example files on that site are not really beginner-friendly or at least, I'm having trouble finding those that are. All of this is being done on a Linux environment. Thanks.
