What is the status when the LEDs are blinking for the USB-KW24D512 dongle? Is there a way to upload default firmware via the USB

Hi Albert,

The LED behavior depends on the application that is flashed. Considering Thread Applications, blinking both LEDs means that the device is in Factory default state (not joined to a specific network).

Regarding the methods for updating via the USB, this could be done if the board is flashed with a bootloader application. In our sdk an example of bootloader(in this case for FRDM board, but could also be updated for USB board) is at the following location:

....\MKW2xD_ConnSw_1.0.2\boards\frdmkw24\wireless_examples\framework\bootloader_fsci

C or Python Scripts for using with fsci bootloader are:

...\MKW2xD_ConnSw_1.0.2\tools\wireless\host_sdk\hsdk\demo\FsciBootloader.c

...\MKW2xD_ConnSw_1.0.2\tools\wireless\host_sdk\hsdk-python\src\com\nxp\wireless_connectivity\test\bootloader\fsci_bootloader.py

and documentation: ...\MKW2xD_ConnSw_1.0.2\docs\wireless\Thread -> Kinetis Thread Stack and FSCI Bootloader Quick Start Guide.pdf

Let us know if you need more details.

Regards,

Ovidiu
