🐛 device.manufacturerData is undefined in iOS

[luca-tomasetti]

Prerequisites

• I checked the documentation and FAQ without finding a solution
• I checked to make sure that this issue has not already been filed

Expected Behavior

After starting a scan with startDeviceScan() I'm expecting to receive the manufacturerData populated in the found device.

With a previous version of the library (2.0.3) in parallel with MultiPlatformBleAdapter 0.1.9, the manufacturerData is normally populated, both with iOS and Android (used the same devices for triggering the bug).

Current Behavior

The manufacturerData field in the found device is not populated, but undefined.

Everything is fine with an Android phone, but using iOS the manufacturerData is not defined, just the rawScanRecord.

This issue is related to #1138, which was supposed to be fixed in the latest version (3.1.2) but I am experiencing the same issue.

Library version

3.1.2

Device

iPhone 12 Pro (17.1.1)

Formatted code sample or link to a repository

const bleManager = new BleManager()

const services = [/* my services */]
const options = { allowDuplicates: true }
bleManager.startDeviceScan(services, options, (err, device) => {
    console.log(device.rawScanRecord) // <-- always populated
    console.log(device.manufacturerData) // <-- populated only in Android
})

Additional information

I'm using MultiPlatformBleAdapter 0.2.0

[luca-tomasetti]

I did some more testing and it seems like the bug appears after the major update to 3.0.0 and MultiPlatformBleAdapter 0.2.0.

With 2.0.3 and MultiPlatformBleAdapter 0.1.9 the behaviour is as expected.

[projectnatz]

I also experience the same problem (3.1.2). Does anybody know a quick patch to add?

[roys-qlog-co]

for me 2.0.3 and 3.1.2 not showing manufacturerData
using iphone 11

[intent-kacper-cyranowski]

Hi everyone
Is anyone still struggling with the issue?

[luca-tomasetti]

Hi @intent-kacper-cyranowski, for now I'm using this package with version 2.0.3 and MultiPlatformBleAdapter 0.1.9.

I will update my project with your new version (3.2.1) and check it tomorrow with an iOS device.

[luca-tomasetti]

I updated to the latest version and after testing on iOS 17.5.1, the bug seems resolved 🥳

I will perform more tests later but everything seems as expected!

[intent-kacper-cyranowski]

@luca-tomasetti thanks for confirming that it works as expected!
I will close this issue. Anyone that comes with similar problem should open it's own issue as this one should be unrelated
