The device's advertisement data is incomplete.

[BinGarfield]

Operating system: Windows 10, 11
Node: v22.14.0

I found that advertisement data was missing from the Bluetooth device data I searched.

However, I found using a Bluetooth assistant tool that the advertisement data actually exists.

Is there any way to solve this? Or is it that it doesn't support retrieving advertisement data?

Additionally, I encountered an error when using this method: Device is unreachable while discovering services.
const { characteristics } = await device.discoverSomeServicesAndCharacteristicsAsync( SERVICE_UUID, [BLE_CHARACTERISTIC.NOTIFY, BLE_CHARACTERISTIC.WRITE] );

I look forward to your reply, thank you.

According to your screenshot, there’s no advertising data included. The device is only advertising a service UUID and a local name - exactly the same information that Noble reports. You can see the 0x1218 service listed under serviceUUIDs along with the device name.

The part you highlighted in the Noble output is manufacturer-specific advertising data, but that field doesn’t appear at all in the screenshot from the app, so it’s not actually being advertised there.

Well, manufacturerData doesn't exist. I expressed it incorrectly and I'm sorry for the misunderstanding.
Actually, what I want to say is whether there is a way to obtain the information in the screenshot below, such as "AD Type"
( It would be great if we could obtain the raw data of the advertisement ^0^ )

I printed out all the device information I searched for, but I couldn't find it. If there are any other ways, please let me know.

Looking forward to your reply.
thank you very much !

you have this information parsed. Look at connectable parameter for example. I dont see anything missing in noble.

After scanning, the peripheral information was obtained. The advertisement information only includes "locaname, manufacturerData, serviceData, serviceUuids, txPowerLevel", but I need other AD types, such as "Appearance, Flags", which were not found in "@ stoprocent/nose".

Looking forward to your reply.
thank you very much !
