RE: Alexa Gadget Sample App on Laird DK using NRF connect App

1. I assume you're referring to the nRFConnect app for Desktop, and not the app for Android/iOS? You can use the desktop app for most of its features with a Laird DK as well, except the Bluetooth Low Energy application, which is locked to SEGGER IDs from our DKs and Dongles, as making sure that the BLE application works on any kind of board is too much maintenance for us to have considered, seeing as there are so many various evaluation and development kits out there that are configured differently. Other than that, the other applications should work as intended on all nRF devices connected to a J-Link.

2. According to the Laird DK user guide the external LF crystal is available if you'd like to use it, but you can also configure the application to use the RC oscillator by adding these configs to your prj.conf file.

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y

3. Not as far as I know, no.

Best regards,
