Headache about how to make your device going wirelessly? Want to have Bluetooth connectivity implement but worried about there is no resource to support firmware code developing ? Raytac AT command modules is the best ideal solution to enable the project having a breakthrough achievement quickly without writing a line of code or building up a design of RF hardware.

AT command stands for Attention Command, which is the most ordinary, easy and widely applied protocol to connect and bridge between IoT devices. Learning from Bluetooth Classic Serial Port Profile (aka SPP) experience, Raytac has been using UART service (ask NUS, Nordic UART service) since 2016 to assist customers proceed the Bluetooth project development. With full experience accumulated from projects, Raytac released the fist AT command module in 2018. Until now, Raytac AT command modules have been widely applying in different applications and successfully easier the project development and shorten the schedule.

Raytac keep improving to meet your demand now and future. When IoT device goes smaller become a trend of fashion, Raytac headed for it. Today, Raytac is happy to announce there are 2 new AT command modules released which are MDBT42T & MDBT42TV, which will have 2 kinds of antenna option available for each model. The modules are smaller than ever which benefit for the applications with space constraints design, also an optimized hardware module design to enable the module not only small but low cost. Raytac keep striving to make it better.

Raytac today announced (Central / Master) AT command dongle released.

Part No.:

MDBT50Q-RX-ATM

Raytac AT Command Module Family

nRF52840 is Nordic’s latest and advanced solution, which brings a new interface “USB” from other lines, has drawn the attention among developers.

Raytac developed AT Command (Master / Central ) solution based on nRF52840 solution, fulfilled the demand of USB interface, missioned to deliver a full coverage of AT Command product line.

Raytac’s nRF52840 USB AT Command dongle, MDBT50Q-RX-ATM is a BT5, FCC/IC/CE/Telec/KC/SRRC/NCC/RCM/WPC pre-certified dongle which is eliminating the need for RF design expertise, and speeding time to market for complex M2M IoT applications.

AT command module is an easy solution provides developers a quick breakthrough to Bluetooth connection. Without firmware effort needed, simply have commands setting on MCU and the start to enjoy the implement of bridging connectivity between devices through Bluetooth.

After Raytac’s completed both Central (Master) & Peripheral (Salve) role AT command module projects, the USB interface has brought up the strongest demand by developers.

Raytac nRF52810 Module Incorporated AT Command Over UART Service (NUS) Coming Soon!

2018 年 02 月 25 日2018 年 03 月 28 日by Raytac CorporationLeave a comment

UART Service (NUS) is the most convenient and common Bluetooth Lower Energy proprietary service for all developers.

Raytac has introduced NUS (UART) BT4.2 and BT5 solution in previous article.

Nordic nRF52810 UART service (NUS) Solution (Raytac Module: MDBT42Q-192K)

nRF52 series SoC has below features rather than nRF51

1. nRF52 supports Longer Package MTU
(500 Bytes for Baudrate 9600 / over 10K for 115200 or 230400)

2. nRF 52 has over 10 times higher transmission speed than nRF51

3. nRF52 only needs 1/10 (or less) transmission time than nRF51

Raytac has been hearing from developers about the demand of AT command over UART service based on Nordic Solution.

Learnt from customers’ feedback, Raytac realized that Long Package MTU is the recent critical demand for all customers and IoT applications.

As such, Raytac hardware team has selected Nordic nRF52810 solution , powered by firmware design team to develop a coming AT Command Over UART Service Solution.

The features of the AT Command Over UART solution not only brings a cost effective module, but an easy and user familiar method enables an easy and time-to-market efficiency.

nRF52810 UART service (NUS) Solution (Raytac Module: MDBT42Q-192K)

2017 年 12 月 13 日2019 年 08 月 14 日by Raytac CorporationLeave a comment

Nordic released nRF52810 aimed to provide a low entry barrier for developers to explore Bluetooth Low Energy implements.To improve the effective cost, nRF52810 has provided a limited RAM (24K) and Flash Memory (192K) specification.

Among the BLE implements, Raytac is aware that the UART service (as known as NUS, Nordic UART service) is the most common and widely applied service which is used to called as SPP in classic Bluetooth.
