DA 14681 wearable dk

Hi, when i use the da 14861 wearable development kit, when i connect it to the laptop through micro-usb and i launch the smartsnippets, i press detect deices generally it cannot detect the device, showing this message "

  • No devices have been detected.
    Note that devices are detected via JTAG.
    Please make sure that your device has either
    an integrated JTAG or a JTAG cable attached

i checked two usb cables and all my usb ports, and i checked it in two pc;s. when i connect the dk it flashes the two leds one red one green so i quess it should work fine.what should i do. Also i would like to ask if there is a costum service in Patras, Greece and a phone number.

Thank you in advance

Hi ksalgado,

Hi ksalgado,

Many thanks for your question online. Please notice that the micro-USB port is only for charging functionality. In case of debugging and downloading code through SmartSnippets Studio, you should use an external board named Connection Interface Board (CIB). The Wearable reference design does not have JTAG on board, so that why the SmartSnippets cannot detect it.

Please read section 12.4 Connection with CIB of UM-B-076 DA14681 Wearable Development Kit Software Manual in order to check how the Wearable should be connected with CIB. You will also find steps for downloading firmware in next section.

Can you please let me know if you already have the CIB or you missing it?

In DA14681 Wearable support portal, you will find all the available documentation you will might need.

In case of starting your own project, please keep in mind that the DA14681 Wearable Development Kit is pin to pin compatible with DA14683. For new designs, we strongly recommend the usage of DA14682/3 SoCs.

Hi, as i said here: https:/

Hi, as i said here: https://support.dialog-semiconductor.com/forums/post/dialog-smartbond-bluetooth-low-energy-%E2%80%93-hardware-device-reference-designs/wearable i have a problem with the wearable, as it seems like dead. i connected as said in the 12.4 section with the pc and i built the wrbl project. after that the screen of the wearable is shut off, even when i connect it with the pc it doesn't flashes. in the above link it is said to try to download the firmware to the wearable. But when i connect the components as said in the section 12.4 i have the beforementioned message.What should i try ?

Hi ksalgado,

Hi ksalgado,

Please check the attached image and the steps below. Can you please double check if you have the same hardware setup?

  1. Connect the CIB with your PC via the USB connector
  2. Flip the switch it the position “ON”
  3. Set all the required jumper headers
  4. Connect the CIB with the Wearable board
  5. Flip the switch on the Wearable board in the position “DOWN"

 

Thanks, PM_Dialog
