#include <bluetooth/bluetooth.h>

How to modify Legato so i can use #include <bluetooth/bluetooth.h>
Using WP7702, Legato 21.05.0

I also need
glib.h
hci.h
and other stuff to make a bluetooth gatt app

I have a modified yocto so wifi/bluetooth is enable and working from terminal

2

do you find those .h in WP7702 toolchain or legato framework?

I see them in the .leaf directory but not in the workspace

/home/pm/.leaf/wp77-toolchain_SWI9X06Y_03.00.13.00-linux64/sysroots/armv7a-neon-poky-linux-gnueabi/usr/include/net/bluetooth/bluetooth.h

I have tried to add the following in legato application:


#include <net/bluetooth/bluetooth.h>

And then add the include path in cdef:

cflags:
{
    -I/home/owner/leaf/leaf-data/wp76/wp76-toolchain/sysroots/armv7a-neon-poky-linux-gnueabi/usr/src/kernel/usr/include/
}

It can find the bluetooth.h, but it has other error that you might need to look into:

BTW, I suggest you cross compile your native-c application with the WP77 toolchain first.

I get the same!
I feel like the wp77-toolchain need to be recompiled somehow with bluetooth and other libs?

I am building a component in VS Code with the rest of our application

I am wondering if you should build your application inside yocto source instead of toolchain
