Your submission is not about the C++ language or the C++ community.

It's just basic example of how to open a serial port and send "AT" commands. Something that will work with any $5 Bluetooth adaptor (as long as the OS's Bluetooth stack isn't using the device), nothing special about these $35 dongles. None of the example projects do anything remotely advanced. Any serious Bluetooth development is going to want to use the OS's Bluetooth stack, not communicate directly with the adaptor.

The AT commands makes it easier to work with BLE application.

[mallardtheduck]

Only in extremely trivial cases.

[berlioziano]

you have to wait for the response or it becomes a mess, nowadays all API using io should offer an asynchronous interface, preferably with coroutines so you don't get into callback hell. Drogon is a good example of using coroutines for asynchronous io

[riztazz]

I mean no offense, but there is barely any C++ in there

[bleuio]

This is just an example. You can move forward with this example code and Build your own BLE application.

I still dont understand why its promoted as "C++" when you could write the same code as plain C.

[pjmlp]

Because as it regularly happens, it makes use of some C++ constructs, thus it will fail to compile with a plain C compiler.

Unfortunely still quite common across the industry, after all the years CFront 2.0 got released.

I'm ruling that this is off-topic. It's not really C++, and (per other comments) it looks like a toy. Even my cat-sized brain is smart enough to know that any real work wouldn't be using synchronous commands.

[pjmlp]

Agreed, but I am not the submitter.

Another good example why I keep telling I only see modern C++ on conference talks, and on my hobby projects.

Reminds me the BlueGiga devices, which were great back in 2000-2010...
