[nRF52833] NRF_ERROR_NO_MEM for sd_ble_gap_adv_start()

[abhiash_sl]

Hello Experts,

I am writing a code for nRF52833 using the SDK nRF5 version v16 using the Segger Embedded Studio as development environment.

In my code when sd_ble_gap_adv_start() is called, I get the error NRF_ERROR_NO_MEM.

i.e. SVCALL(SD_BLE_GAP_ADV_START, uint32_t, sd_ble_gap_adv_start(uint8_t adv_handle, uint8_t conn_cfg_tag));

/**@brief Function for starting advertising.
*/
static void advertising_start(void)
{
ret_code_t err_code;

err_code = sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
APP_ERROR_CHECK(err_code);

err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING);
APP_ERROR_CHECK(err_code);
}

I have created the pca10100/s140 folder and modified the .emproject file.

Below are linker specifications

linker_section_placements_segments="FLASH RX 0x0 0x80000;RAM RWX 0x20000000 0x20000"

linker_section_placement_macros=
"FLASH_PH_START=0x0;
FLASH_PH_SIZE=0x80000;

RAM_PH_START=0x20000000;
RAM_PH_SIZE=0x20000;

FLASH_START=0x27000;
FLASH_SIZE=0x59000;

RAM_START=0x20002ae8;
RAM_SIZE=0x1d518"

Also I tried other values of RAM_START and RAM_SIZE from ble_app_hids_keyboard example but still the same error.

The project settings show the flash_placements.xml being used and the .emproject file values exported when seen through common settings 

Cannot understand what should be modified.

Thanks in advance for your support

Best Regards

AbhiAsh

The Debug Terminal shows the following output

Hi Abhi, 
Error 12292 = 0x3004 mean it's BLE_ERROR_INVALID_ADV_HANDLE not NRF_ERROR_NO_MEM.

Please take a look at the documentation of sd_ble_gap_adv_start() and try to debug the 2 possible causes of the problem:

@retval ::NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied:
* - Invalid configuration of p_adv_params. See @ref ble_gap_adv_params_t.
* - Use of whitelist requested but whitelist has not been set, see @ref sd_ble_gap_whitelist_set.

Thanks Hung for the reply.

I am kind of new to this development environment.

The handle was the problem. The previous handle is used for beacon while I am using advertisement module

ret_code_t err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);

Hi Abhi, 
Please clarify if you've solve the problem with the handle ? 
Note that the Softdevice in nRF5 SDK can only do one set of advertising at a time. So you won't be able to advertise 2 sets at a time (in nRF5 SDK). 

Also, please be aware that nRF5 SDK is deprecated since 2020. For new development it's strongly recommended to start with nRF Connect SDK.
