NRF_ERROR_SDM_LFCLK_SOURCE_UNKNOWN

[steve_in_australia]

Hello,

We are adding BLE scanning to an ANT product.

We have been using SDK 10.0.0 from the beginning, so we use the Example below. 

          SDK 10.0.0.0\examples\ble_central\ble_app_multilink_central\pca10028\s130\arm5_no_packs\ble_app_multilink_central

Test board is

          PCA10028 V1.2.0  2016.19

Problem: SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL);

                returns NRF_ERROR_SDM_LFCLK_SOURCE_UNKNOWN (0x1000).

We have converted SOFTDEVICE_HANDLER_INIT to code for debugging, see below, that's where we see the ERR_CODE 0x1000

We have seen DevZone comments that SDK and 51422 incompatibility can cause this error message.

Is this our problem?

Thanks,

Steve

static uint32_t BLE_EVT_BUFFER[CEIL_DIV(BLE_STACK_EVT_MSG_BUF_SIZE, sizeof(uint32_t))];

ERR_CODE = softdevice_handler_init((NRF_CLOCK_LFCLKSRC_XTAL_20_PPM),
                                                                BLE_EVT_BUFFER,
                                                               sizeof(BLE_EVT_BUFFER),
                                                                NULL);

We have seen DevZone comments that SDK and 51422 incompatibility can cause this error message.

That most likely is the case. Since using clock source of NRF_CLOCK_LFCLKSRC_XTAL_20_PPM on a compatible device should not return this error.

Thanks for that Susheel, but what do we do next? PCA10028 V1.2.0  2016.19 and the SDK10.0.0. are Nordic products. If they don't work together we need instructions what to do. Can Nordic please try it? Which SDK is compatible? 

[steve_in_australia]

Problem is solved: s130 2.0.1 isn't compatible with SDK10.0.0.

s130 1.0.0 has to be used.
