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

2018 年 05 月 21 日 by Raytac Corporation Leave a comment

Raytac would like to remind following external MCU setting for first time connection with AT command DK Board.

1. Baud Rate: Default setting is 9600 without Flow Control

2. UART PD default setting is “Low”

*a. MCU output set as “Low” to connect the DK Board

*b. If MCU can not set up output “Low”, please use jumper to connect UART PD onto DK board to stay in “Low” (please refer to below pictures）

3. AT Command edit can only be committed under the DK boards is “No-Bonded” (Not Paired).

4. DK default broadcasting set as 30 sec and then enter to sleep mode. Developers can press wake up button to restart the broadcasting!

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

2018 年 05 月 17 日2018 年 05 月 17 日 by Raytac Corporation Leave a comment

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!

2018 年 02 月 25 日2018 年 03 月 28 日 by Raytac Corporation Leave 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.
