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

2018 年 05 月 21 日2018 年 11 月 06 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!

2018 年 05 月 17 日2018 年 11 月 06 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.
