Time until the SoftDevice is enabled

takashina hiroki

SDK: 15.3.0
SoftDevice: S132
Device: EYSHJNZWZ (nRF52832)

Please tell me about "nrf_sdh_enable_request".
This API only makes a request, so I understand that the SoftDevice is not yet enabled just by calling the API.
When will the SoftDevice be enabled?
How long does it take for the SoftDevice to be enabled after this API is called?

    Hi there,

    I don't think the time has been specified. 

    If you're using an external crystal, then the Softdevice will wait for the LFXO to ramp-up before it returns to the program. You can manually start the crystal before calling nrf_sdh_enable_request() to shorten the waiting time.

    regards

    Jared
