I started encountering a problem when calling bt_enable(ReturnCallBack). The ReturnCallBack function returns the error ENOBUFF (105). I assume it's a memory allocation issue in the Bluetooth stack. How can I solve this? How and where is the Bluetooth stack memory managed?
void ReturnCallBack( int err )
{
if ( err )
{
LOG_WRN( "ReturnCallBack err %d", err );
return;
}
k_sem_give( &bluetoothReady );
}
[...]
bt_enable( ReturnCallBack )
my prj.conf
