[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?

Why on earth are you talking about linker settings. The linker has absolutely nothing at all to do with it. Read the documentation on the error message which tells you the attribute table size isn't valid, despite the fact you're passing in 0 which should be the default and ought to work. Go give it a proper value which is bigger than the minimum and a multiple of 4.

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.

That's not the S110 v 8 eader file. So you are compiling with the wrong headers. So you have the wrong structure so you're not initializing it properly. Use the right header which has that error message described in it.

Oh, you are correct. I accidentally set the path to use the S120's ble.h. My bads.
