I'm trying to use USB KW41Z as openthread device, and LPC55S69 as a connecting board with KW41Z for its PUF feature. Since both of the boards supports SPI and I2C interface, the way of connecting these two boards will be either one of them. However, I have problem of letting USB KW41Z and LPC55S69 communicating with each other. Besides, could you let me know how to set up wires between them?
Please consider that the USB KW41Z does not have the interfaces to work and develop, it is intended to be used mostly with the sniffer-like capabilities with special device.
For a better understanding on the available interfaces in the board you are using could you please help me check the USB-KW41Z Sniffer/Development Board User's Guide ?
