MDBT42T & MDBT42TV Joined Raytac AT Command Codeless Module Family

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.

AT-Command Module Tutorial ~ About First Time Connect To The DK Demo Board

Raytac AT Command Family

With strong demand for AT command module coming up from markets, here provides an easy introduction about hardware and software setup work for Raytac’s AT command module demo board for quick start.

AT-Command Module Tutorial ~ How To Read Battery Status?

After AT Command Module, MDBT42Q-PAT, released, Raytac has received several feedback from developers about “How to read battery status through AT command?

In order to help developers quickly set up the environment, the tutorial hereby is using a AT command DK board which deployed MDBT42Q-AT, to demonstrate how to work out this function.

First of all, the DK board schematic is provided in below for reference.

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

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.

MDBT42Q-P192K-nRF52810 Nordic.jpg

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.
