Radar sensor Forum Discussions

Hi,

We started a while ago working with the BGT60TR13C development kit to follow the suggested learning curve before jumping into our own design. We have already tried some succesful configurations by using the dev kit and Radar Fusion GUI, so now we have moved to our own PCB, where we have a dedicated host MCU (instead of the one from the Dev Kit).

The SPI communication in our board between the host and the radar works as expected, as also does the initialization (get device id to verify not only that the radar is connected but also that it is a BGT60TR13C, amongst other steps). Just for some context, we are also following the guidelines provided in Inifineon's repository (https://github.com/Infineon/sensor-xensiv-bgt60trxx). We are also using the default presence settings configuration parameters provided with the SDK.

So far so good... except that there was no way of getting data into the FIFO, it constantly reports as if it is empty. We focused on using the data test mode, to discard any issue with the configuration, but still in the data test mode (SFCTL:LFSR_EN= 1B), the FIFO is never filled.

We are following the same sequence as the one implemented in https://github.com/Infineon/sensor-xensiv-bgt60trxx and double checked it also with the one described in the datasheet (10.Enhanced Functions->10.1 Data Test Mode).

Any clue were the issue could be? Is there any other step needed to make the test mode work that is not documented in the datasheet? We are running out of ideas here, so we would really appreciate any help anyone could provide.

Thanks in advance.

Hello,

i am trying to get get Demo BGT60LTR11AIP running in CW mode in Python.

As described in the SDK documentation, the setting for the CW mode would be mode = 1.

But when i run the" device.get_next_Frame(<time>) " method in python, i get the following error:

"ErrorTimeout: device did not acquire a complete time domain data frame within the expected time (IFX_ERROR_TIMEOUT)"

I am not able to find a solution for this problem, to gather the data in cw mode.Am i missing something?

Also i can not find examples for the Sensor, as there seems to only exist examples for other Radarsensors in radar_sdk\examples\py

SDK: 3.5.1

FW 2.6.0

Best,

Kai

Hello sir,

Greetings of the day!

We are developing one project using BGT24LTR11N16E6327XTSA1. For that we need 24GHz  4x1 microstrip patch array antenna.

Can you please suggest the antenna part number or can you provide the document related to the design of  24GHz  4x1 microstrip patch array antenna. 

Thanks & Regards

Hi,

I am working with BGT60TR13C. I have a demo kit from Infineon on which I run the presence detection code. We have developed a custom PCB with that same BGT60TR13C with ESP32 as MCU interfacing. I received a presence detection code from Infineon running on ESP32. It is working and detecting presence. The output of both the custom PCB and Infineon demo kit slightly differ. 

With the same position of both boards, one by one the detection angle in custom PCB is lesser than in the demo kit. The demo kit gives a wider range whereas the custom PCB has less range in terms of angle. I doubt about RF-related issues. for that, I am attaching the PCB reference here . In the Custom PCB center is the Sensor and the rest area is copper and some other sensor. 

Radar configuration data is the same in both the cases I have reverse-engineered and make than same in both.

I just got the demo board for the BGT60TR13C and when I connect it, the Radar Fusion GUI v3.5.4 (on Windows 10) does not detect it.

In the device manager it shows up as a "broken" serial device. The status LED on the board blinks green.

Radar Baseboard MCU 7 V2.2 04-2023

What can I do to debug this?

Thanks

This is the error I run into when configuring one of the my scripts:

Error using RadarDevice.check_error_code
a frame was dropped due to communication or buffering issues (data rate too high for
underlying link or memory allocation mismatch) (IFX_ERROR_FRAME_ACQUISITION_FAILED)

These are the parameters I am using:

This seems to run fine on the RadarFusion GUI, so is there a reason why this wouldn't work in a script?

Dear all, 

I'm in the process of identifying the optimal solution for a range-angle and segmentation algorithm, tailored to a customized device configuration as shown in the figure below. My system is STM32H7, 550MHz with EtherNet TCP interface. Could you please recommend the most suitable configuration for both algorithms?

Thank you very much.

Hi,

May I ask if it's possible for me to read the raw data from BGT60TR13C Radar Demo Board directly by connecting SPI or UART pins of Demo Board to ESP32 board?

For now, the BGT60TR13C Radar Demo Board can only transmit the data to my laptop via USB. However, I want to configure it to wireless data transmission with Bluetooth or WiFi, which reminds me of connecting it with ESP32. I noticed that there are Arduino MKR connectors available on Demo boards but I don't know how to configure them to make MCU transmit raw data via those pins.

May anyone offer me any help? It will be appreciated a lot!

Regards,

Sam

I am using the static_distance.py algorithm from the RDK. Is it possible to change the radar field of view from the standard 40/45 degrees? I would like to narrow this 3D conical field of view to receive data from the radar at a more precise location. If this is possible, which file can I edit to achieve this?
