BLE C++ Wrapper

[schef]

I am trying to wrap BLE into a nice c++ class. For this i am using ble_app_uart example. I think it was working fine until i was up to clean the helper functions. After that i got error_code: 8 at SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);.

Here is a full example. ble_app_uart_modified.rar

In file ble_wrapper.cpp:626 when i comment command ble_advertising_start there is no error.

I can't seem to find the reason. Is is possible that this is connected to C++ class? Are there some other ideas? Is there a way to narrow the issue?

Thanks.

I moved to sdk14 but here you go. gist.github.com/.../f945611d3835dc708371269407b29c6b

Nice work, thanks.

you could construct your singleton like below, this is stronger.

static BleWrapper &getInstance() {
   static BleWrapper instance{};
   return instance;
}

Thanks for the suggestion. What do you mean by stronger?

this is thread safe when using c++11 and up. your are sure to have only one instance.

How would i implement this instead of my code?
