BLE_STACK_HANDLER_INIT vs SOFTDEVICE_HANDLER_INIT + softdevice_ble_evt_handler_set

[julian]

I saw two different way to ini ble 1 ) BLE_STACK_HANDLER_INIT

2. SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, false);

err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch);

seems it is also ble_stack_evt_schedule vs softdevice_handler_init

which case we use 1), which case we use 2)?

thanks

This depends on SDK version. Version 5.0.0 introduced the SOFDEVICE_HANDLER_INIT(), so if you use this version or later (recommended), you should use this.

If however you're limited to 4.4.2, you should use BLE_STACK_HANDLER_INIT().

Thanks!, I am using 4.4.2, is there a upgrade guide to upgrade to 5.2?

[julian]

after upgrade to 5.2 in keil, in app_error.h, it reports nrf_error.h can't found

Unfortunately, we don't have an upgrade guide as such, but this shouldn't really be very difficult.

If you have a custom project that you want to upgrade, you may need to change the include paths, as the softdevice header files have moved from Include/ble/softdevice to Include/s110. Similarily, other header files may also have moved. I'd recommend you to compare project settings between a native 5.2.0 project and your own to get things working.
