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!

  1. Hello,
    This link above (AT Command Module Spec Sheet (Please Click Me)) does not work for me. Can you enable it, please?
    Also, which Nordic SoftDevice must I program for the smallest MDBT42V modules to be able to control them from an external MCU by using AT commands?
    Many thanks,
    Gabriel
