The Russian Mikoyan MiG-29 is a fourth-generation, twin engined air-superiority fighter.

Developed in the 1970's by the Mikoyan design bureau, the legendary MiG-29 and the larger Sukhoi Su-27 were developed to counter American F-15 and F-16 fighter aircraft.

Arrows has used state-of-the-art engineering and testing expertise to develop the dual-64mm EDF MiG-29 confident that this MiG-29 surpasses the performance and features of any other MiG-29 on the market today.

The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. The nRF5340 is an all-in-one SoC, including a superset of the most prominent nRF52® Series features. Features like Bluetooth® Direction Finding, high-speed SPI, QSPI, USB, up to 105 °C operating temperature, and more, are combined with more performance, memory, and integration while minimizing current consumption.

Nowadays, many supermarkets and storehouses require the scanner for goods detailed account. In the big space, the line scanner is not easy for working. For working convenience, the scanner manufactures make wireless scanner. And Bluetooth module cost and consumption are great than other wireless modules. Currently, the Bluetooth scanner is a very popular Bluetooth product.

Eddystone-UID Parameter
Eddystone-UID is a component of the Eddystone parameter for BLE beacons. It contains 36 hexadecimal digits composed of 20 hexadecimal digits Namespace ID, 12 hexadecimal digits Instance ID and 4 hexadecimal digits RFU, split into 3 groups, separated by hyphens.

Eg. 0102030405060708090A-0B0C0D0E0F00-0000

Each of the 3 groups must contain the following number of characters per section:

First section: 20

Second section: 12

Bluetooth technology is one of the widely used wireless communication standards. From the perspective of market and industry trends, the popularity of Bluetooth Low Energy (BLE) consumer devices such as wearable devices, mice, joysticks, BLE, etc. The cost advantage of semiconductor materials and the tendency of mobile devices to have more than BLE GATT (Generic Attribute) Profile and computer system-side BLE HID (Human Interface Device) Profile standard communication protocols make Bluetooth technology mainstream.

In the past decades, cables have been helping people a lot to make phone calls and play music, but it can be annoying when the cables tangled up or when you want to walk around and make phone calls. Bluetooth is a perfect alternative technology for those people who want to get rid of these annoying issues.

Wi-Fi Alliance was established in 1999. After more than 20 years of development, at the end of 2018, Wi-Fi Alliance announced that it will change the naming method of the Wi-Fi standard, and will no longer use the 802.11 electronic engineering terminology. The new generation of Wi-Fi 6 belongs to the sixth generation of wireless LAN technology. What is the difference between Wi-Fi 6 and Wi-Fi 5?

What’s the difference between WI-FI 6 and WI-FI 5?

List of Wi-Fi naming conventions:

802.11ax = Wi-Fi 6

802.11ac = Wi-Fi 5

802.11n = Wi-Fi 4
