S120 RC clock problem

[Alexander Maurer]

Can the S120 work without RTC XTAL? Iam using SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION, false); but it still hangs in the softdevice_handler_init function. The internal RC is working fine with the S110 for my hardware?

Thanks Alex

Hi Petter

Thanks for your answer

I have tried all defines and just the NRF_CLOCK_LFCLKSRC_SYNTH_250_PPM is working. The SVC to the S120 is only returning with the "NRF_CLOCK_LFCLKSRC_RC_250_PPM_8000MS_CALIBRATION" and the error_code is 0x1000 == "NRF_ERROR_SDM_LFCLK_SOURCE_UNKNOWN" Iam using S120 with the fwid: 0x4a s120_nrf51822_0.8.0-3.alpha_softdevice.hex and nRF51822QFAAC0.

I have another problem the function err_code = sd_ble_gap_scan_start(&m_scan_param); is returning with an error_code = 0x3001 BLE_ERROR_INVALID_CONN_HANDLE

Thanks Alex

I just tested the nRF51822 QFAAC0 with SoftDevice S120 0.8.0-3.alpha and the newest SDK. I used the ble_app_hrs_c example found in nrf6310->S120->experimental. I'm using the development kit. It worked fine, with different low frequency clock sources.

Are you using the newest SDK?

What example are you using?

Are you using the evaluation kit, the development kit, or something else?
