Bluetooth: Extended Inquiry Request: can't set service UUIDs (IDFGH-10266)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.

General issue report

Hello!

I use ESP32 with IDF v5.0.1.
I need to configure a SDP service record and place the same UUID in the Extended Inquiry Request (EIR).

I used this code to create a SDP record and it is works pretty well:

char *sdp_service_name = "TEST RECORD";

esp_bluetooth_sdp_record_t record = {};
record.hdr.type = ESP_SDP_TYPE_RAW;
record.hdr.uuid.len = 2;
record.hdr.uuid.uuid.uuid16 = 0xff00;
record.hdr.service_name_length = strlen(sdp_service_name) + 1;
record.hdr.service_name = sdp_service_name;
record.hdr.rfcomm_channel_number = BT_IAP2_RFCOMM;
record.hdr.l2cap_psm = BT_L2CAP_DYNMIC_PSM;
record.hdr.profile_version = BT_IAP2_PROFILE_VERSION;
esp_sdp_create_record(&record);

I see my test record in sdptool output:

Service Name: TEST RECORD
Service RecHandle: 0x10001
Service Class ID List:
  "" (0xff00)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 1
Profile Descriptor List:
  "Serial Port" (0x1101)
    Version: 0x0102

Then I used this code to configure the EIR data:

   esp_bt_eir_data_t eir_data;
    eir_data.fec_required = true;     /*!< FEC is required or not, true by default */
    eir_data.include_txpower = false; /*!< EIR data include TX power, false by default */
    eir_data.include_uuid = true;     /*!< EIR data include UUID, false by default */
    eir_data.flag = 0; /*!< EIR flags, see ESP_BT_EIR_FLAG for details, EIR will not
                          include flag if it is 0, 0 by default */
    eir_data.manufacturer_len = 0; /*!< Manufacturer data length, 0 by default */
    eir_data.p_manufacturer_data = nullptr; /*!< Manufacturer data point */
    eir_data.url_len = 0;                      /*!< URL length, 0 by default */
    eir_data.p_url = nullptr;//(uint8_t*)&eir_uuid;                  /*!< URL point */
    esp_bt_gap_config_eir_data(&eir_data);

Then I captured EIR with wireshark when hcitool scan is performed.
I see that after this code UUID fields appeared, but they are empty!

They must contain UUIDs from the SDP.

So I can't understand how to add UUIDs to the EIR data. I don't see any API besides esp_bt_gap_config_eir_data().
Could you help me to find the solution, please?

Currently ,there is no API to add UUIDs to the EIR data ,and we may provide them in future version.
Now I think you can do this by modifying the function.
This function creates EIR tagged data and writes it to controller.
