Hi, currently i am running MQTT Client : Human Presence Detection using KIT_CSK_BGT60TR13C. When I doing step 3 at the Operation it shows an error at the Eclipse IDE Terminal. The error "MQTT connection failed with error code 0x8260007. Retrying in 2000 ms. Retries left: 75"

How to solve this error ? I would prefer to use Local Mosquitto Broker than AWS

Dear Infineon team,

there is unfortunately no tolerance given for the 1.8 nF capacitor in parallel to the IC of the part TLE4942-1C.

Could you please provide the tolerance of the bypass capacitor?

Thank you for your support.

Please tell me about the influence of AC fluctuation of the power supply to VCC of BGT24LTR11N16 on the oscillation frequency.
The phenomenon I observed was that when the VCC power supply fluctuated with a 13kHz sine wave at 50mVp-p centered at 3.3V, the oscillation frequency of TX output fluctuated over a width of 10MHz around the set value of 24GHz.
When the variation is small enough (<<10mVp-p), it varies within 1MHz.
(Other conditions)
・V_TUNE has ±1mVp-p variation at 1.5V input.

  The operating power supply specification is within 3.2 to 3.4V.
I have no idea the possible expected value of this phenomenon as a device behavior.
If the behavior is impossible, please let me know if there are other factors.
 Also, if there are any specifications regarding power supply ripple, please let me know.

My device is Distance2GoL. I want to change the congifuration in the DAVE IDE by GUI mode. I change the DAVE APP: TX_EN, but when I rebuild this project and flush the new firmware. Nothing changed.

The original value for the "initial output level" is low for DIGUTAL_IO_BGT_TX_EN. But I want to change it as HIGH:

I rebuild this project and flushed the firmware into my board. When I use OSC to check the TX_EN， I find it does not start with a high level but still with a low level. I am not sure if I really change the setting by this way. Could you please tell me if I want to change those DAVE APP's setting like this GUI method, how can I flush the change into my board? Is it still same like when I changed the code, then rebuild the project and then flush.

Hi,

I'm looking for a way to properly perform the BGT60TR13C sensor re-initialization procedure.

Regarding the example in the link: https://github.com/Infineon/sensor-xensiv-bgt60trxx

In case, if the xensiv_bgt60trxx_get_fifo_data function returns status = XENSIV_BGT60TRXX_STATUS_GSR0_ERROR

What should I do to re-init the radar sensor?

Actually, I have tried to read the FIFO for a long time (A few days) without any problem. But just want to handle if any problems appear when reading the FIFO data.

I have tried restarting the LDO power and then call 3 below functions to re-init the sensor but it does not working.

Could you point me how to re-init the sensor if the xensiv_bgt60trxx_get_fifo_data function returns errors?

Thanks!

I am using BGT60LTR11SAIP with XMC4500. I can adjust the detection threshold from 66 through 2560, which corresponds to approximately 0.5 meters to 7 meters. Is there any information regarding the detection range corresponding to each value?

And when I approach my hand very slowly towards the sensor, it fails to detect the movement. Is there any relationship between the speed of the object and detection? If yes, what are they?

When could I expect no motion behavior? I mean, how long should an object be immobile to trigger the no-motion state,the sensor timeout?

Hello,

I'd like to know the BGT60LTR11AIP Receiver Conversion Gain, plase let me know where is that description.

Best Regards,

Hi,

I am using the BGT60TR13C  for vital sign extraction and I saw in other questions in the forum that the BGT60TR13C only outputs the I signal of the radar.

I tried to use the progression of each complex frequency component over time (chirp-to-chirp) as an IQ signal for each frequency component, as you suggested. But it is not working and I cannot extract meaningful information. For comparison, I did manage to extract specifically respiration rate using only the amplitude data in the output.

I would like your help to better understand how to extract phase from the output data and detect small vibrations.

Thank you!
