GATT Service Discovery Failure on SIG BASE UUID

[matt_wilson]

Support,

I've encountered a challenge while integrating my product with device from a third-party. Unfortunately, they've utilized the SIG base UUID for their unregistered vendor services, and with their product already on the market for a few years, they've expressed no intention to revise this approach. I'm integrating with two of their devices, which I'll distinguish as device A and device B for our discussion. Establishing a connection with device A poses no issue, as its service characteristics are easily discoverable due to the use of 16-bit UUIDs. However, with device B, their oldest product, I'm not as fortunate. During the discovery process on device B, I encounter the error BLE_GATT_STATUS_ATTERR_ATTRIBUTE_NOT_FOUND. Research conducted using tools such as nRF Connect for both iOS and desktop reveals differences in how devices A and B present their services and characteristics. I have attached screenshots and logs from these tools for reference. From what I've gathered from another topic on this support site, the Softdevice manages the SIG Base UUID internally in a manner that I haven't fully grasped yet. It seems like I need to adopt an approach where I utilize the full 128-bit UUID instead of the 16-bit UUID for service discovery. From the log screenshots below, you can clearly see the differences between the to devices.  However, I'm uncertain how to implement this when the SIG base UUID is in use, which is causing some confusion in getting this to work. I've reached the limits of my knowledge in resolving this issue and need assistance from support to guide me toward a solution. Are there questions I'm overlooking, and do you fully grasp my problem? If so, is there a viable path to resolving it? Thank you.

This screenshot merges the log outputs from nRF Connect for iOS. As evident, the implementation of the SIG Base UUID appears to vary slightly in the way it's being published. I'm having difficulty comprehending these two differences: the utilization of 128-bit and 16-bit UUIDs.

Here's a screenshot of the device connect to nRF Connect for Desktop

 

As always, thank you for the amazing support!

Hello,

When working with vendor-specific UUIDs that do not use the BT SIG base UUID, you must first add the 128-bit base UUID to the SoftDevice's UUID table. This allows the application to reference the UUID later. New base UUIDs are added through the sd_ble_uuid_vs_add()  function.

Note: If sd_ble_uuid_vs_add() returns NRF_ERROR_NO_MEM, it means you must increase the 'NRF_SDH_BLE_VS_UUID_COUNT' in sdk_config.h to allocate additional UUID slots in the SoftDevice table.

You can take a look at the Nordic UART Service Client  project for a practical example of a client using a 128-bit vendor-specific UUID. This client include the following service and characteristics:

Code to add the Nordic UART service base uuid

#define NUS_BASE_UUID                   {{0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0xA3, 0xB5, 0x00, 0x00, 0x40, 0x6E}} /**< Used vendor-specific UUID. */

...

uint32_t ble_nus_c_init(ble_nus_c_t * p_ble_nus_c, ble_nus_c_init_t * p_ble_nus_c_init)
{
    uint32_t      err_code;
    ble_uuid_t    uart_uuid;
    ble_uuid128_t nus_base_uuid = NUS_BASE_UUID;

    VERIFY_PARAM_NOT_NULL(p_ble_nus_c);
    VERIFY_PARAM_NOT_NULL(p_ble_nus_c_init);
    VERIFY_PARAM_NOT_NULL(p_ble_nus_c_init->p_gatt_queue);

    err_code = sd_ble_uuid_vs_add(&nus_base_uuid, &p_ble_nus_c->uuid_type);
    VERIFY_SUCCESS(err_code);
    ...

Notice that the NUS_BASE_UUID symbol is represented in little-endian format, as opposed to the big-endian representation that tends to be used in user-facing applications and documentation. Also, the 'p_ble_nus_c-->uuid_type' holds the index of the base UUID, which the app uses as a tag to reference the UUID.

If anything is unclear, please let me know.

Vidar,

Thanks for getting back to me promptly. I fully understand your reply. My product also interfaces with multiple other vendor products through their distinct UUIDs and services. When I integrated other products a few years back, I followed the NUS client model as outlined.

In my explanation, both devices utilize the SIG base UUID for their services. This can be verified in the screenshot of the nRF Connect logs I posted.  My client code for connecting to Device-A functions smoothly. Since the services of Device-A and Device-B appear identical, I aimed to utilize the same code to connect to either device. When connecting to Device-A, there are no issues with discovering the service. Upon reviewing the logs, we observe that it returns the short UUID (2-byte). However, Device-B is now returning the full UUID (16-byte), and inexplicably, it cannot be discovered, resulting in an "attribute not found" error. So in short, the discovery process cannot find the service "0000FFE0-0000-1000-8000-00805F9B34FB" (Device-B) but can find "FFE0" (Device-A).

Logs from nRF Connect for both devices, with the highlighted comparison.

Device-B debug output from the connection attempt reveals failure due to the inability to find the service FFE0 during the discovery process.

Based on what I've seen, Device-B is advertising its service with a 128-bit UUID. We see that in the logs.  Since it's using the SIG base UUID, is the Softdevice defaulting to searching for services with a 16-bit UUID, which might explain why it's not discovering the service? Device-A is broadcasting a 16-bit UUID, which can be accurately identified since it also employs the SIG base UUID.

Matt,

Sorry, I misunderstood the problem; I assumed it was the other way around. That is, I assumed you were able to discover the service on device B.

I don't understand why iOS doesn't discover the service as having a 16-bit UUID for device B considering it's using the same reserved base UUID. I tried replicating this by using the UART peripheral sample and replacing the NUS base UUID with the Bluetooth SIG's, but that resulted in the same behavior as seen with device A.

There must be some details in the specification that I'm not aware of. I will need to investigate this further on my side. The advertisement payload should not have any influence on the service discovery.

Best regards,

Vidar

[matt_wilson]

Vidar,

Thanks for investigating this. I recall having a GATT Browser app installed on my Mac. I utilized it with the two devices, and you can also observe where it highlights the disparities between them. Device-A reports the short UUID while Device-B reports the full UUID. I'm able to discover and connect to Device-A with the short UUID when utilizing the SIG base UUID.

Device-A

Device-B

Matt,

Are you able to capture a sniffer trace (nRF Sniffer for Bluetooth LE) of the service discovery procedure for both device A and device B? I'm hoping this might provide us with some additional clues.

[matt_wilson]

I've got a Bluetooth packet logger installed on my phone. I've used it to gather these logs for each device. If this information isn't sufficient, I can switch to my sniffer setup and attempt to capture more data.

As I examined the logs, I observed variances highlighted in the screenshots. Notably, there's a differences in the response to a GATT primary service declaration request. I speculate whether the issue revolves around the 128-bit UUID response. Given that this UUID is categorized as a SIG base UUID, could it be plausible that the Softdevice is encountering parsing difficulties?
