problem with BLE HRSC - error 0x8502

[dragilla]

Hi, 

I'm on SDK 17.0.2 and SD 340. Trying to combine BLE services as Central server with BLE HRS_C example. The idea is to read the BLE HRM and also to be able to connect to my app using a BT app on my mobile phone. I can do both but in separate apps :) When I try to combine them I get the following error:

<error> nrf_ble_lesc: nrf_crypto_ecc_key_pair_generate() returned error 0x8502.

Can you help?

Thanks

I added the cc310_backend_init.c file as it was missing, and now I get 

<error> nrf_ble_lesc: nrf_crypto_init() returned error 0x8570

edit: I found some previous tickets about this error. For me, moving the BLEadvertising and ANT after the following block of code helps.

peer_manager_init();
db_discovery_init();
hrs_c_init();
scan_init();
scanning_start(&erase_bonds);

The scanning starts, ble services and ant works. However there are still problems with HRS_C functionality. The BLE HRM does not pair and there is no read of HR from it. But maybe I shuold create a new ticket for it?

Sorry for the delayed response.

 But is it able to discover and connect the peripheral? Pairing is often not required for Heart rate sensors.

Yes, I skipped the pairing and bonding process and everything works. Thanks
