how to use metawear-sdk-cpp in C on Ubuntu.

wchai

  Greeting,

   wrote a c program to interface with the api without luck.

   Anyone could kindly share a sample C/C++ code? Thanks in advance.

• What code have you written thus far?
  
• How have you compiled the code?
  
• What errors are you seeing?

     tried to write C code to call metawear API to get battery status, started with the following  

     simple code to test out the C code. 

   #include "metawear/core/connection.h"
    #include "metawear/core/metawearboard.h"
   
    int main(int argc, char **argv) {
        MblMwBtleConnection btle_conn = { write_gatt_char, read_gatt_char, enable_char_notify };
        MblMwMetaWearBoard* board = mbl_mw_metawearboard_create(&btle_conn);

       

        
    }

   I was using g++ to compile the code and specifies the header locations, but the compiling errors

   complaining cannot find the header files, such as module.h, model.h, metawearboard_fwd.h. 

   noticed that there was no connection.h in core directory.

"metawear/core/connection.h" was moved to "metawear/platform/btle_connection.h" in a later release, looks like the documentation wasn't updated to reflect the change.  That issue aside, it also looks like your g++ flags are not correct.  Please post your g++ command as well as the compile errors.

Hey, I am facing the same problem.
The command is used was just "make sampleFile" which is g++ sampleFile.cpp -o sampleFile.
What is the correct way?

Add the usual g++ include and library flags
