Updated MetaWear C++ API (WinRT) 0.5.0 not working

afzaal · September 2016

Previously my UWP C# sample was working with old MetaWear API.

I upgrade the MetaWear device firmware to v1.2.3

Also I update the API WinRT to 0.5.0.

I compile the sample code and running.

For paired device it creates board using mbl_mw_metawearboard_initialize().

It initialize board using mbl_mw_metawearboard_initialize().

It gives exception on following line while configuring for gyro;

mbl_mw_gyro_bmi160_set_odr(cppBoard, GyroBmi160.OutputDataRate.ODR_100HZ);

Exception: "External component has thrown an exception."

Did i miss something?

Can you share UWP C# sample for latest API WinRT 0.5.0?

After debugging I able to resolved it and now getting gyro data.

New change in sample is;

- First parameter of writeCharacteristic() is boardPtr and 2nd parameter is gattCharPtr.

- Same case for readCharacteristic().

As these to function pointers are used to initialize the instance of BtleConnection fields writeGattChar & readGattChar.

Hi afzall, I am also getting this same exception. Could you point me in the direction of the sample app you based your writeCharacteristic method on?

Is the boardPtr parameter of type IntPtr?

Base your app off of the uwp starter project.

More I made changes in UWP starter as described in Firmware v1.2.3 Support and API Refactoring;
