How to decode advertising data?

[mento]

I used nRF5_SDK_12.1.0_0d23e2a, SoftDevice 8_9_0。 The peripheral device name is "Nordic"

After central scan, i want to get the device name "Nordic"，i used the following code to decode:

adv_data.p_data = (uint8_t *)p_gap_evt->params.adv_report.data; adv_data.data_len = p_gap_evt->params.adv_report.dlen;
err_code = adv_report_parse(BLE_GAP_AD_TYPE_16BIT_SERVICE_UUID_MORE_AVAILABLE, &adv_data, &type_data);

if (err_code != NRF_SUCCESS) { // Compare short local name in case complete name does not match. err_code = adv_report_parse(BLE_GAP_AD_TYPE_16BIT_SERVICE_UUID_COMPLETE, &adv_data, &type_data); }

Why the ( type_data.p_data) do not have any data? How to get the "Nordic" string? Thanks.

Hi,

You should use the parameters BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME and BLE_GAP_AD_TYPE_SHORT_LOCAL_NAME in the adv_report_parse() functions to search for names.

Check out the function on_adv_report() in main.c file of BLE Multi-link Central Example.

Best regards,

Jørgen
