IWR6843AOPEVM: IWR6843AOPEVM + MMWAVEICBOOST and Arduino UNO: Enabling Uart tx and rx on J5 for radar configuration

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVEICBOOST

Hi,

I am working with the Industrial Toolbox 4.12.1 Vital Sign lab and am attempting configure and start/stop the device from an Arduino using the config port (J5.5, J5.7) connected to the UART pins of the Arduino.

From what I have read in the documentation and other forum posts it seems that UART on the J5 header should be configured in that lab out of the box, however I am not receiving any CLI output over UART when sending configuration commands from the Arduino and it appears that UART is not functioning.

I have verified that my UART code on the Arduino is functioning properly by connecting the J6.9 pin of the MMWAVEICBOOST board to the receive pin of the Arduino and starting the lab using Teraterm to manually send the config and start commands via USB from my computer to the MMWAVEICBOOST. The Arduino code successfully reads the bytes from the data port. 

Upon switching the jumpers back to the J5.5 and J5.7 header pins and sending configuration commands from the Arduino to the MMWAVEICBOOST board, I receive no output from J5 UART to indicate that the commands have been recieved such as the CLI prompt "mmwDemo:/>" or "Done" as observed when sending commands via the Teraterm.

The switches on the MMWAVEICBOOST were initially configured as follows:

To read data from the J6 header for testing, I switched the 3 switch to off. I tried to send and receive data from the J5 header using both of these switch configurations with no success.

Is there anything required in order to setup the MMWAVEICBOOST board to receive and transmit configure and start/stop commands and their associated responses on the J5.5 and J5.7 pins? I am able to communicate with the board from a computer via the USB but not through the UART pins.

What is needed in order to accomplish this?

Best Regards,

Connor
