[SDK 10.0 Scanner Beacon] sd_ble_enable returns error 9

[MANGO]

Using

• IAR EWARM 7.20

• PCA10001 V 2.0.0 (Changed the MCU to QFAAH00 Revision 3)

• SDK 10.0

• SoftDevice S110 8.0

• J-Link Edu

• Example: Scanner Beacon

/********************************************************************/

Hi, I'm using the PCA10001 board. This board had a revision 2 nRF51822 QFAA chip.

I replaced that chip to a QFAAH00 (0x0072) with a heat gun

to test SDK 10 and S110 8.0 codes.

I check with other examples, such as HRS and NUS, to check whether the board works

and it paired with my iPhone 6 plus's nRF Toolbox app with no problem.

After calling ble_stack_init,

the sd_ble_enable function returns error number 9, which means NRF_ERROR_INVALID_LENGTH.

I just migrated to SDK 10. I used SDK 7.2 in the past. So I hope I didn't make a mistake

about the Linker settings.

Anyways, any ideas why sd_ble_enable returns error number 9?

Hi, RK. I said "I just migrated to SDK 10. I used SDK 7.2 in the past. So I hope I didn't make a mistake about the Linker settings.". I just wanted to ensure that I made a proper setting to cut down the problem.

The point is that, at ble.h,

/**@brief Enable the bluetooth stack
@retval @ref NRF_ERROR_INVALID_STATE stack had already been initialized and cannot be reinitialized.
@return @ref NRF_ERROR_INVALID_ADDR Invalid or not sufficiently aligned pointer supplied.
@retval @ref NRF_ERROR_INVALID_PARAM Invalid parameter supplied.

the documentation does not describe why NRF_ERROR_INVALID_LENGTH is returned.

I use S110 8.0. I didn't understand your instruction.

Do you mean to add ble_enable_params.gatts_enable_params.attr_tab_size = BLE_GATTS_ATTR_TAB_SIZE_DEFAULT;?

This shows compiler error since ble_gatts_enable_params_t doesn't have attr_tab_size.
