D Deleted member 103 Guest Apr 5, 2019 #1 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?

techknight Well-Known Member Licensed User Longtime User Apr 5, 2019 #3 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. Upvote 0

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. Upvote 0

It must be said that some 4.4+ devices still did not have the Bluetooth 4.0 hardware even though Android supported Upvote 0
