sd_ble_enable returns error code 5

[George]

I'm trying the ble_app_hrs example on a custom nRF51822 board with s110 6.0.0 softdevice.

Debugging in Keil, the firmware runs fine up to ble_stack_init(). Within ble_stack_init() the call to sd_ble_enable(&ble_enable_params); returns error code 5 (NRF_ERROR_NOT_FOUND).

// Enable BLE stack 
ble_enable_params_t ble_enable_params;
memset(&ble_enable_params, 0, sizeof(ble_enable_params));
ble_enable_params.gatts_enable_params.service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT;
err_code = sd_ble_enable(&ble_enable_params);
APP_ERROR_CHECK(err_code);

I am confused by this as according to the S110 6.0.0 documentation sd_ble_enable() should only return NRF_SUCCESS or NRF_ERROR_INVALID_ADDR.

any suggestions ?

it seems I have found a solution ...I commented out the complete code block shown in my post above and now it works as expected.

Why is this so ?

The SDK v6.0 is for S110 version 7.0.0. If you are using the S110 6.0.0 you have to use SDK version 5.2. The API call sd_ble_enable() does not exist in 6.0.0.

Thanks Ulrich ..now that explains a lot of strange behavior I was finding!

I had completely assumed that SDK 6.0.0 refers to S110 6.0.0 ...thought the version numbers simply followed each other.

Hello !

I am having the same problem but using SDK v6.0 and SoftDevice 7.0.0-3. Is it really safe to comment out the block ? Will the ble stack be enabled ? I have read somewhere that the SOFTDEVICE_HANDLER_INIT macro would enable it but I would like confirmation.

Thanks !
