DA14683-USB disconnecting/crashing

Hello,

I'm evaluating the DA14683 using the DA14683-USB DK. I've compiled and loaded the DialogSemi\projects\workspace-ble-adv\projects\dk_apps\features\ble_peripheral project. After pressing restart I can see the device's advertisements in my BLE development app, and can even connect. However, after ~10 seconds the device disconnects/crashes. I have to hit the reset button again to restart the device, at which point it crashes again after ~10 seconds. It looks like most of the da14683 tutorials and demo code are for the da14683-basic and -pro dks.

1. Are these demo codes and tutorials readily usable on the da14683-usb dk?

2. If no what are the necessary changes that need to be addressed to ensure proper execution of the demo codes on the da14683-usb dk?

3. Are there any resources specifically available for the da14683-usb dk?

Hi electromotivated,

Hi electromotivated,

Please take a look into section 5.16  Power Section from the UM-B-094 User Manual: DA14682/DA14683 USB Kit user manual. It’s available in the DA14683 USB-DK webpage as well. In that section, you will find that there is a switch button (SW6). According to the documents, the DA14683 SoC can be supplied either from the USB port with a voltage of 5V to the VBUS pin or through LDO (U10) with a voltage of 3.3V to the VBAT pin. The power selection is achieved through the switch SW6 (Figure 30, Figure 31). The maximum current for SW6 is 100mA. The default position of SW6 connects the VBUS pin of DA14683 with the USB port (5V). When users/developers need to have full power save and/or battery-operated applications which do not include any USB or charging functionality, then the power supply of the DA14683 USB kit must be from VBAT.

For this mode:

- SW6 must be turned to 3V position (VBAT)

- All the SDK examples can be used and no extra software configuration is needed

Please find more information in section 6. All the available resources for the DA14683 USB-DK can be found in this link :

https://www.dialog-semiconductor.com/products/da14683-development-kit-usb

However, you can use any of the tutorial/documents etc. that are available in the DA14682/683 product page.
