ble_advdata_set

[bom4]

I use SES for debugging,

the chip is nrf52840 with softdevice 140, sdk 15.3

I ported a project from 2017 and now I'm ready to compile all without any error,

but as soon as I am debugging 

the program runs into advertising_init() and ends up in an infinity loop

the ble_advdata_set() returns error code 10 what means that it's an invalid flag

so far I don't know what flags are allowed and were they where set in code

in Infocenter I found only this structble__advdata__t, but still not sure what flags I could set were I set flags

then it leafs the advertising_init() and reenters again. sd_ble_gap_adv_start() returns from now on 8

from now on the program try to ble_advertising_start() and sd_ble_gap_adv_start()  always return 8 and so on (in a loop)

Edit: 26.06.2020 

I dived deep in debbuging spheres and found some additional informations

down in the function I mentionet already is a call to 

sd_ble_gap_adv_data_set() this function gives me the error code 10 -> Invalid Flags

I extracted some defines from this function the hole definition is defined in ble_gap.h

the value witch is given to the function in *p_data has a flag field witch is 6

but 6 is not an invalid flag as you can see 

#define BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE   (BLE_GAP_ADV_FLAG_LE_GENERAL_DISC_MODE | BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED)   /**< LE General Discoverable Mode, BR/EDR not supported. */

is in fact flag value 6: because 0x2 | 0x4 is 0x6 ... so far so bad, whats wrong now?

Hi,

From the migration guide of SDK 15.0:

"The function ble_advdata_set() has been deprecated. The reason is because sd_ble_gap_adv_data_set() has been removed from the SoftDevice API. Instead, you can use ble_advdata_encode() before calling the SoftDevice function sd_ble_gap_adv_set_configure.

You may need to call ble_advdata_encode() twice, because ble_advdata_set() might have both advertising data and scan response data as input. The function ble_advdata_encode() only encodes one at a time.

Advertising parameters are now part of sd_ble_gap_adv_set_configure() instead of sd_ble_gap_adv_start().

For some examples, we have moved the setting of advertising parameters so they are set together with advertising data.

Action: Replace calls to ble_advdata_set() with ble_advdata_encode(). Call sd_ble_gap_adv_set_configure() before calling sd_ble_gap_adv_start()".

But the program is already based on SDK 15.3 I don't understand why nordic changes old SDK stuff that already running software has to be modified... 

for modifications there are the SDK versions in my eyes... otherwise it makes no sence that there are SDK 15.3 and SDK 16.x etc.

Which example did you base your project on and what SDK did you port it from? Did you add ble_advdata_set() to the project? 

[bom4]

I took the ble_app_template from the ble_peripheral folder and because so much changed in SDK I try a quick and dirts solution 

by replacing the changed .c and .h files with the original ones from the old project.

So I didn't add ble_advdata_set() to the project on purpose but maybe it was in the old files I had to add.

the original project has over 1000 lines of code witch mostly cal the nordic HAL, so if I would follow the migration guide, I may end up as an old grandfather and still not running the program.

It seems they gave me wrong information about this projekt as I started.

it was SDK 14.2 they used not SDK 15.3 what explain some issues that I had. 

thanks for your answers
