What Roles Will Bluetooth Technology Play In the Automotive Field?

  The Bluetooth Special Interest Group (SIG) and the market research organization ABI Research cooperated to analyze the future market development of Bluetooth solutions in the new version of "Bluetooth Market Updates". The forecast points out that the annual shipment of Bluetooth devices will increase to 6.2 billion units in 2024, an increase of 2 billion units from 2019. ABI Research's research confirms the great potential of Bluetooth technology in the automotive industry. By 2024, Bluetooth vehicle equipment shipments will reach 109 million units, and in 87% of newly produced vehicles, Bluetooth will become the standard wireless technology. By then, two-thirds of passenger cars, SUVs and commercial vehicles will also be equipped with Bluetooth technology. At the same time, Bluetooth technology can help realize intelligent wireless networks, thereby improving road safety and driving experience. In the future, 4 to 6  Bluetooth wireless sensors  will be used in every ca...

Bluetooth Audio Module with AptX Low Latency

图片
  For many high quality Bluetooth audio products, they will great audio, cool low latency and so on. And provide a good low latency technology is the aptX Low Latency (aptX LL). It reduces delay and improves end-to-end speed of the audio transmission, resulting in a high quality, synchronised user experience. With aptX Low Latency you can enjoy the freedom of wireless for applications such as gaming and watching videos.   Recently, some customer show us, they need a perfect audio and lowest latency on their Bluetooth speaker. In order to have lowest latency, their want choose a codec for the low latency. However the codec have different with their application. After Feasycom engineer evaluation, we suggest customer using the aptX LL, it will convenience for the customer get great audio. In this application, Feasycom audio module FSC-BT802 for the audio receiver. The module FSC-BT802 use CSR8670 chipset, not only support aptX LL, it also support aptX. This module is great for ...

Security Mode Of Bluetooth Module ?Level 3 Or Level 4?

  To whom may concern : What is the security mode of bluetooth module ?Level 3 or Level4 ? 1.Every one can pair with the bluetooth module 2.It will auto connect to the bluetooth module which you have connected last time 3.Need password then can pair with the module 4.Others These are spp security mode ,how about ble security mode ? BLE Security Mode : No password ,the most common method (factory default settings PASSKEY:when pair, it need input any number from 0~999999.(Some android cellphones with poor compatibility for this ,so usually we do not recommend this. SPP Security Mode: SPP:LEVEL 2 ,security simple pairing mode Support pair with password https://www.feasycom.com/blog-598.html

The most common app for the bluetooth device

  Today we are going to recommend most common app for connect you to all of your devices that use Bluetooth Low Energy . For iOS device ,the most common app it is LightBlue®,you can feel free to download from APP Store. 1)LightBlue® can connect you to all of your devices that use Bluetooth Low Energy (also known as Bluetooth Smart, or Bluetooth Light). With LightBlue®, you can scan, connect to and browse any nearby BLE device. 2)For android device ,the most common app it is LightBlue®,you can feel free to download from Google Store. nRF Connect for Mobile is a powerful generic tool that allows you to scan, advertise and explore your Bluetooth low energy (BLE) devices and communicate with them. nRF Connect supports number of Bluetooth SIG adopted profiles together with Device Firmware Update profile (DFU) from Nordic Semiconductors and Mcu Manager on Zephyr and Mynewt. When you use ''nRF Connect '' ,i have to mention that this app default setting is 20 bytes ,you need se...

How to Use AT Commands To Control Bluetooth Modules Over The Air With Feasyblue APP?

  Since we can’t carry computers/laptops all over the place all the time, sometimes we might want to know how to use AT Commands with Smart Phones. Today Feasycom will get you out of the mist. https://www.feasycom.com/blog-use-at-commands-to-control-bluetooth-modules.html First of all, we need to download an APP called Feasyblue. (We could get this App from both Appstore or Google Play) Second, we could go through the following steps to get works done: a) Connect the module with feasyblue. b) Send ‘$OpenFscAtEngine$’ to the module, then you will get ‘$OK,Opened$‘. It means that you’ve got access to the developer mode. c) Send any AT commands, and after typing the AT command, turn the HEX mode on, adding ‘0D 0A’ to the end of the string.(See the reference photos below) d) Turn the HEX mode off, and then send out the command. e) And now the AT command will work the same as using PC serial tool. Please note: Every time you need to send an AT command to the module, you have to go throu...

GATT Configuration File-Easy To Use

图片
  BLE provides several common attribute (GATT) profiles for common applications that simplify firmware and compatibility standards. Examples include Current Time Service (CTS), “Find Profile” (FMP), “Heart Rate Service” (HRS), Wireless Lighting Control (“Grid Profile”), etc. These profiles allow peripherals and servers to communicate with each other using predefined data structures with little overhead. This allows BLE to use simpler protocols than connection options such as Wi-Fi. In addition, high data transfer efficiency is achieved. If the application fits in an existing GATT configuration file, it is easy to use because it reduces firmware development time and opens the door to existing application compatibility. A list of standard GATT profiles can be found on the BLE SIG website. To further simplify the firmware creation process, Cypress IDEs such as ModusToolbox provide an easy-to-use graphical interface for BLE. These configurators provide an option to add a standard GATT ...
