nRF51822 ble_app_hrs_c doesn't work.

[Kuba]

Hi! I have a problem with testing ble_app_hrs_c. I am using nRF51822 develpment board + nRFgo Motherboard. Softdevice is S120 1.0.0 1alpha, SDK version is 5.10. Specifically after execute line 338 in cnn_mngr.c file ( uint32_t retval = sd_ble_gap_scan_start(&m_scan_param); ) retval is 0x00003001, wich means NRF_ERROR_SVC_HANDLER_MISSING. I don't understand what is a reason of this error. How to fix this error? I am trying to modify ble_app_hrs_c to test data transfer rate in my custom app. Is there another way to test it?

Best regards, Kuba

Hi,

I had the same problem. I noticed that version 0.8.0-3 of S120 works fine for me. After flashing version S120 1.0 it wasn't recognized by nrf studio as s120 softdevice. Using version 0.8.0-3 it is visible in nRFStudio as softdevice by displaying S120_nRF51822-0.8.0-3.alpha as FW in region 0.
