Yes, softdevice_handler_init called inside the macro SOFTDEVICE_HANDLER_INIT. Anyway, I discovered the problem wasn't the handler. The proper error code was NRF_ERROR_SDM_INCORRECT_INTERRUPT_CONFIGURATION (0x1001) that comes up because I had set the adc IRQ priority level too high (0). To discover it I had to disable all the IRQs and than enable them once a time. Finally, when I founded the issue was caused by the adc module, I set its IRQ priority to APP_IRQ_PRIORITY_LOW (3) and everything starts to work fine!

Do you mean softdevice_handler_init()? So 0x0001 is returned? Could you go inside it and see which function that returns NRF_ERROR_SVC_HANDLER_MISSING? What SoftDevice version are you using?

Actually I do need to remove some characteristics when the user disconnects from the device and add them again only when the user provides a correct pin number in the unique visible characteristic. Debugging the code I discover that the problem is in the ble_stack_init() where, internally, the SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL) return this error: NRF_ERROR_SVC_HANDLER_MISSING.

You are only adding services aren't you? That shouldn't be a problem, the post you refer to are about removing services. Anyways, what error code does sd_softdevice_disable() return?
