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)

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.
