In this issue, we will briefly touch on Bluetooth technology and its development process. Also, we will talk about the steps Ozdisan Elektronik has taken to serve its customers who “use” or “want to use” Bluetooth in their projects. Even when Ericsson introduced Bluetooth, a short-distance communication technology, in 1994, it did not think that this technology could reach these levels. When we say “Bluetooth”, we always think of an inefficient technology that could communicate over short distances and connect to only one device. However, we see that many terms such as Bluetooth 4.0 / 5.0 / 5.1 / A, BLE / Mesh have appeared recently. At this latest point, and contrary to what is known, the transmitting range has also been greatly increased and now it can be connected to multiple devices using Bluetooth technology. Compared to this, the power it spends was reduced to a minimum. As a result, we are now seeing Bluetooth technology in places that require low power consumption, such as wearable technology, especially the Internet of Things. Therefore, the number of companies working in Bluetooth field and the number of companies producing Bluetooth modules has increased.

Each year, a different theme dominates the Embedded World embedded systems fair. Whatever the trend is, the products presented are always associated with that trend. As a result of the field researches and studies about the direction of technology we conducted before going to the Embedded World Fair this year, we saw that the technology and systems at the fair were progressing exactly in the same direction we had predicted. The entire concept of the fair was based on connecting objects or systems to the Internet in some way. As Ozdisan Elektronik, we have signed a distributorship agreement with Taiwanese Raytac at this fair that we participated.

Raytac is a company that produces Bluetooth modules. The integrations, which are the basis for its modules, are manufactured by the world-renowned Nordic Semiconductor company. Today, when everything is modular now, we often see chip manufacturers as well as companies that produce modules with these chips. Raytac is an approved partner of Nordic Semiconductor company, and it has also received FCC, IC, CE, Telec (MIC), KC, SRRC, NCC, RCM, WPC certificates for all the modules it has designed. In addition, it provides smooth services to its customers by performing all the required RF tests. Raytac’s existing structure can adapt to all kinds of projects by producing products in all combinations that its customers may need. Communication can be established at lower distances with products with a PCB antenna on them, while communication can also be established at medium distances with products with a chip antenna on them. In addition, in products with a uFL connector, the distance can be increased to maximum levels by making an external antenna connection.

While the range of the Raytac modules used with the chip antenna is 400 meters, the tests conducted with the uFL connector showed that the Raytac modules could exchange data at a distance of 2 kilometers. This is a fairly sufficient distance in areas such as communication and data collection. Raytac product group consists of 3 different structures in total. These vary according to the structure of the Bluetooth chips manufactured by the Nordic Semiconductor company.

Raytac has designed a demokit for each product family so that the testing and development phase of all products can be facilitated and accelerated. Thus, customers who want to work with Bluetooth technology or develop projects can develop their codes with the help of development kits before designing their own PCBs. As a result of the distributorship agreement with Raytac, Ozdisan Elektronik has added Raytac’s entire product range and development kits to its inventory. So, all our customers who are interested in this subject can easily buy these products from us and try them by themselves.
