how to get FWID if it doesn't exist in UICR？

Hi Deng, I tried to do this but had no luck. After erasing and programming the softdevice I tried to retrieve the UICR with the --hexuicrinfo option but I get all 1's:

% nrfjprog.exe --hexuicrinfo hexfiles/s130_nrf51822_0.5.0-1.alpha_softdevice.hex

UICR->CLENR0 = 0xFFFFFFFF

UICR->RBPCONF = 0xFFFFFFFF

UICR->FWID = 0xFFFFFFFF

UICR->XTALFREQ = 0xFFFFFFFF

Hopefully someone from Nordic can help you with this. You'd think there is a way to do this, because nRFgo Studio reports the Config ID (subversion_number) after softdevice programming.

By the way, how to use nrfjprog.exe cmdline tool to retrieve FWID?

Hopefully you can use sd_ble_version_get() as described in the S110 and S120 documentation. You pass a pointer to a ble_version_t structure, on return the 16-bit subversion_number field contains the information that used to automatically appear in UICR FWID with earlier SoftDevice releases.
