Android Question BLE not supported by android 4.4.4 ?

[Deleted member 103]

Hi,

according to the example of Erel, BLE (Bluetooth Low Energy) should be supported starting with android 4.3.
I am currently trying on my old Nexus 7 with Android 4.4.4 and the sample says that BLE is not supported.
Does anyone know the problem?

Does the device hardware support ble?

yea that is the issue. Your Nexus 7 may only have Bluetooth 3.0 hardware in it. There are 2 versions of the Nexus 7. 2012, and 2013. Only 2013 has the BT4 hardware.

a good test is using the "nRF App Connect"

Only 2013 has the BT4 hardware.

Also, BLE is an optional part of BT4. Just because box or specifications say BT4 (or 4.0 or 4.2), doesn't guarantee the device supports BLE. No prizes for guessing how I found that out.

BLE Checker (by Michael Yan) is the easiest way to confirm BLE hardware present.

And if it is, then +1 f0raster0 re Nordic Semiconductor nRF Connect app. I tried a few, and thought that app was the best for connecting to and exploring BLE peripherals.

Thank you guys!
Then BLE is not only dependent on Android 4.3+ but also on the Bluetooth version.

It must be said that some 4.4+ devices still did not have the Bluetooth 4.0 hardware even though Android supported

Yes, that's the problem!
In Android, there is no standard where each manufacturer must comply.
