BLE Raw Advertising Data Cropped

Former Member over 5 years ago

Hey all,

I want to pick up the device name from advertising (or paired) BLE peripherals, but Ble.ScanResult.getRawData() removes/does not include the AD type 9 (local device name) in the raw data, even though I can see it in the packets on my phone!

The device I am currently testing on is a MoveSense that advertises AD types 1,2 and 9, but to be honest, almost ALL peripherals close to me report a null device name in Device.getName(), ScanResult.getDeviceName() and AD types 8 and 9 parsed from raw data.

What's going on?

Thanks,

/Micke

Frankly, what's the point? This part of their empire is clearly just ignored by Garmin. Has anything happened on that ticket for the last 9 months? Nope. Has anyone from Garmin actually answered? Nope…

Sounds like this bug report:

BTW, here is an easy way to see what can be seen in a CIQ BLE app:

BTW, on real 245 and 945 devices, starting a while back, device.getName() returns an empty sting but works fine in the sim.

Sort of, but not exactly, the GUID service data is not at the end of the advertisement.

Thanks jim_m_58 , I did verify with your app as well, to rule out errors on my end, but you show the same thing, i.e. no ID 9 data is present in the "raw" data.

Add anything you find to the bug report I linked to.

Nope. Chances of them actually fixing anything prior to like 2 years after my deadline are slim. I'd much rather switch to another platform. I am not saying this as critique to those from Garmin working on this, it is probably just a lack of resources or policy decisions from higher up, but... that doesn't change the fact that IQ development is... problematic, due to the lack of responsiveness from official Garmin (seems to me like you Jim is 96% of this forum, but as far as I know you are not with Garmin).
