AWR6843AOP: Same

Part Number: AWR6843AOP

Hi!

I am evaluating a AWR68xx_AOP device.  However, I am completely new to these devices so this is probably a total newbie question.

I have used the mmWave Demo Visualizer web app and see the device working.  Which is great!

However, now I want to connect it to a separate computer where I send the configuration information via a serial port (USB) and receive the output via another serial port.

If I configure the device via the web app and then close the web app, I can send a new configuration to the device via the serial port from a python script and can read the output on the other serial port, also using a python script.  However, if I do not start the process with the mmWave Demo Visualizer and use the "Connect Hardware" 'button' at the bottom of the screen, things don't work correctly.  That is, I can write the config information to the device, but based on the output it doesn't appear to be working correctly.

How can I do the initial configuration of the device such that the serial input and output work correctly?

Thanks!

  • I figured it out.  What needed to be done was configuring the output data port.  

    By sending the following to COMs port 0 (/dev/ttyUSB0 in my case):

       configDataPort 921600 1

    It configured the output port correctly. 

    Next, I was able to send my configuration commands to COMs port 0 and read the output on COMs port 1 (/dev/ttyUSB1).
