 I would like to point your attention to the new application node which focus on interoperability between different Android and iOS smartphones. This application node was released in February 2021 and it shows reports and comparison of different Android and iOS phones. The focus of testing was the basic functionality such as discovery, connection and various guide procedures and some more advanced application scenarios such as BLE pairing and measurement of data transfer. In fact the application scenarios is something you can test with your own smartphone thanks to the BLE data throughput example which is part of the official cube package and that's what I would like to show you right now. So the WBNucleo is now flashed with the throughput application and as you can see it outputs some application traces in the terminal window via the virtual comport and we see the device is now simply advertising. I will open the STBLE toolbox application on my smartphone and connect to the device. The name of the device is DDDTserver. In the traces we can notice the connection interval is exactly 45ms which seems to be an optimal value with regards to throughput. The bandwidth BLE service allows us to measure the speed of transfer in both directions so we can start with the upload so this is the direction from the phone to the WB and we can see the measurement every second is about 77 kilobytes per second on average and this is true for the 2 megabit phi. We can change the phi by pressing switch number 2 and you see the speed drops. We can also test the other direction so now the data will flow from the WB to the phone and we need to initiate that by pressing switch 1 and again we see a speed of about 43 kilobytes per second on 1 megabit phi and if we change the phi the speed will increase to about 70 kilobytes per second. This is a nice and easy test to measure throughput on your phone and if you inspect the application note you will see the numbers very quite significantly depending on the phone and also on the version of the OS.
