 Welcome everyone, my name is Salvo from SC Microelectronics and today we showcase a demo for ultra low power and low cost Bluetooth solution. The key element of this demo is a feature supported by our Blue Energy LP, a programmable Bluetooth Low Energy 5.2 system on chip. This feature is called Low Energy Codify and it's a robust modulation scheme introduced in Bluetooth 5.0 where thanks to data redundancy it increases the robustness of the demodulation and extends the range of the wireless link. With a Codify link layer the payload can be encoded with two different data rates. 500 kilobits per second for the SU modes where two symbols represent 1 bit and 125 kilobits per second in S8 mode where 8 symbols represent 1 bit. Here we have a Blue Energy LP Kit acting as a central and it's connected to a remote device acting as a peripheral at a distance of about 60 to 70 feet in our office space here in Santa Clara and despite the distance between the two nodes it's a quite harsh environment to establish a reliable BLE link because we have different objects in between the two boards and also people moving around. The tablet is connected to a remote camera to monitor the remote nodes and for the purpose of a visual demonstration we developed a simple and user-friendly graphical user interface to monitor the link at both application level and link layer level. With this user interface we can monitor some quality indicators of the link. The application level we monitor the number of write operations from the central device successfully completed out of the last 20 write attempts. The closer this number is to 20 the fewer write operations have failed and a link layer level we observe within a rolling time window of 10 seconds the percentage of the packet received with CRC errors, the missed BLE events and finally the packet error rate. As soon as we switch from the encoded 1 megabit per second to the codified with this button we can see that the link quality increases and this can be observed both at the link layer level and the application level and it is evident for example by looking at the missed BLE connection event which is reduced in the latter case. Ultimately the developers can monitor the link to determine which one of these two moderation schemes best fit the application needs in terms of performance, robustness and reliability of the link.
