Arduino101 BLE how to sending data

hello arduino~
i try use ble send data arduino101 another
so refer heart rate monitor sample code

my code looks this

code: [select]


#include <curieble.h>

    bleread | blenotify, 2);  // remote clients able notifications if characteristic changes

well code not made code
full of errors, compiled anyway
i use joystick shield , read data that
and send specific data via ble

return topic
when upload , connect android nrf toolbox applications
nothing shows in graph

why happens?
because service read analog sample?

if want send data service fit me?

please me

full of errors, compiled anyway

i haven't looked through code specific problems, if code compiled lot of warnings, that's sign program may not behave in way you're expecting

fixing warnings might go long way you!
