ble_gap_cfg_device_name_t USAGE

[arshdeep]

Hi,

We have a requirement of reading the BLE Advertising name from flash instead of predefining it in as a MACRO.  I saw in the notes it says to use ble_gap_cfg_device_name_t. But I don't know the actual usage of it. Can you please direct me to an example where this API has been used.  

I have seen the structure reference for this but I am still not sure where and how to use it. 

Shall I remove SVCALL(SD_BLE_GAP_DEVICE_NAME_SET, uint32_t, sd_ble_gap_device_name_set(ble_gap_conn_sec_mode_t const *p_write_perm, uint8_t const *p_dev_name, uint16_t len)); from my code and add ble_gap_cfg_device_name_t ?? 

using nrf52840 and SDK 15.0.0

Please suggest!!

Thanks

Hi,

What is the purpose of placing the name in flash? If you set it directly in the application, it will still be stored in flash in application code.

You can find an example in this post.

Best regards,

Hi,

We are storing our serial number in flash and we want the device to advertise by that serial number.

uint8_t * adv_address = 0x40000;

ble_cfg_t* p_ble_cfg;
ble_gap_cfg_device_name_t device_name;
device_name.p_value = adv_address;

Now can you tell me how to change the gap_params_init():

static void gap_params_init(void) {

BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);

err_code = sd_ble_gap_device_name_set(&sec_mode,
(const uint8_t *)DEVICE_NAME,
strlen(DEVICE_NAME));

}

 Thanks,
