Original question:

AWR1843BOOST: AWR 1843: How to use the sensor over CAN protocol

AWR1843BOOST: Connection using USB causing data loss

Mihir Salot

Part Number: AWR1843BOOST

We have integrated AWR 1843 Boost through an USB to RPI, on a drone to log sensor's reading using this code (*https://github.com/ibaiGorordo/AWR1843-Read-Data-Python-MMWAVE-SDK-3-) 

The code works perfectly fine on ground and we are able to log all the data, without any issues. However, the code stops retrieving data in a few seconds after takeoff everytime. (In air our drone has higher vibrations and current withdrawal).

1)Can you help us figure out what may be the cause of the issue we are facing while reading the sensor in flight.

2)In case we want to use the sensor over serial instead of USB what changes do we need to make?

    Hi Mihir,

    It's kind of hard to think of something that could cause an issue with communication alone. Can you confirm that the application on the AWR was running without any issues? Need to understand where it stopped in the application (on the AWR) to result in such a failure. Can you also confirm there was no power interruption, or any improper cable connections that could come out when the drone takes off?

    Regards,

    The connections are clean, only one usb connection to RPi. The code shows dataOK as true, till the drone takes off, and turns to false a few seconds after the drone takes off. These are the only observations I have as of now. YOu can suggest any other things i need to check out.

    Also meanwhile, can you help us with this:

    In case we want to use the sensor over serial instead of USB what changes do we need to make? (along with details of resistors and components that are needed additionally)

    Hi Mihir,

    This issue is not something we can reproduce on our end so we will not be able to provide extensive support on this. You will have to perform a debug during this transition state and get back with what happened to the radar device. If you can provide us with this info, we will be able to resolve it.

    Are you running the application from the flash or using CCS debug mode? You will have to do something to get the state of your application right before it failed.

    Regarding the serial transfer, which protocol are you planning on using?

    Regards,
