ManufacturerSpecificData is not working properly

[Ruifen9]

I have a low-power Bluetooth device that advertisement data like this:
[
02 01 05 08 09 61 6e 74 68 65 72 6f
09 ff 11 02 11 02 d9 21 a3 38
1e ff 11 02 11 02 d9 21 a3 38 21 43 01 d9 00 10 19 44 45 4c 20 68 73 65 4d 20 47 53 54 42
4a 00 00 00 00 00 00 00 00 00
]
// result.getScanRecord().getManufacturerSpecificData()
//or
//result.getScanRecord().getManufacturerSpecificData(0x0211)

The ManufacturerSpecificData I read sometimes is like this：
[ 11 02 d9 21 a3 38 ] (When the signal is weak, more is like this)
, sometimes it is like this:
[
11 02 d9 21 a3 38 21 43 01 d9 00 10 19 44 45 4c 20 68 73 65 4d 20 47 53 54 42
4a 00 00 00 00 00 00 00 00 00
]
And I want to get all the advertisement data, but I didn't find the relevant method.
I hope I can get your reply, thank you.

With this: https://developer.android.com/reference/android/bluetooth/le/ScanRecord.html#getBytes() method you may get all the data received, not only Manufacturer Data. I think, if the data are truncated, the only solution is to ignore such packet and wait for another.

Thank you very much for your reply. This method will still get incomplete data, and most of them come from devices with weak signals.
