Alexa Gadget Sample App on Laird DK using NRF connect App

[mdot]

Hello,

I recently bought the Laird BL654 DK which is based on the nRF52840. (www.lairdconnect.com/bl654-ble-modules-and-development-kits). I was interested in running the Alexa Gadget Example provided via the NRF Connect Kit (developer.nordicsemi.com/.../README.html). I was hoping if someone could guide me on the steps required to make this possible?

1. Can i just use the NRF connect app just as i would use it for any Nordic DK?
2. I am aware that the Laird DK uses a different clock source than the Nordic DK. Where does that change need to be made?
3. Are there any other changes that i would need to make to ensure that the Alexa Gadget works on the Laird DK?

Thank you for your support and Help.

Hi

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,

Simon
