CC2745R10-Q1: Channel sounding SDK9.10

Ram Mon

Part Number: CC2745R10-Q1

Tool/software:

Hello; 

In fact we have been testing the channel sounding SDK, we want to use the PBR+RTT but we found that in this sdk only PBR is developped.

1. The question can we add the RTT methods based on this SDK does it has all necessary features. the sdk support the RTT if developped.

2. When we change the ACI upper that 1, we run the distance measure.py file it gives always ACI=0 and the distance, confidence and quality has a fixed random measurement.

3. When upgrading the number of the car-node antenna, it is described that we have to enable PBEGPO2 and PBEGPO3.

  

4. For those pin it is written that those pin are 

So the question, do we need the antenna booster pack to upgrade the number of antenna. If yes, how can we get it.

 

5. Another question is related to the handover example, when trying to use two key_nodes with one car_node it always gives an error of not knowing the nodes.

is there a more detailed description on how to test it.

Thank you;

Best Regards;

    Hello Ram, 

    1. Have you attempted to run mode 3 steps (PBR + RTT)? This can be changed within the Python script (ble_device_car_node_with_distance.py) under cs_config_params. See the image below: 

    2. Can you send me the parameters you are configuring under cs_config_params? I do not see the initial problem with the ACI. I set mine to 7 for 2x2 antenna configuration. Additionally, the value I assume you are seeing if 0xFFFF FFFF in hex, or 4,294,967,295 in decimal. I am currently looking into that. 

    3. That is correct. Please reference the Preparing Python and CCS Environment in the documentation for more information on configuring the antenna configuration. 

    4. The image you provided is the antenna board for Angle of Arrival, not Channel Sounding. For channel sounding, we use a different boosterpack. Let me know if you have BP-EM-CS booster packs to use. The Angle of Arrival boards will not work for Channel Sounding. 

    5. Please reference the Connection Handover documentation. Can you provide me with the error seen, and what steps you are taking to enable the demo? 

    Let me know. 

    Thanks, 
    Isaac

    Hello Isaac; 

    Thank you for your response.

    1) Yes, i tried the mode 3 it is already done by default, i want to understand where the RTT method appears on the car_node project because i succeded in understanding how pbr is implemented but when searching for RTT i cannot find the equation.

    2) For setting ACI to 7, it works but always gives kind of random value 4,294,967,295.

    4) In fact i don't have the BP-EM-CS booster packs, i searched on TI website does not exist, i wonder how can i get it, and if it is a must have to perform the channel sounding demo.

    5) I have implemented the instructions indicated on the Connection Handover documentation but always i got an error

    ""AttributeError:"NoneType' object has no attribute 'open_psm',

    as i searched i found that is related to l2cap, so i disabled the l2cap, the error disaper, but now it display that scan enabled and then is stucked there no more output.

    Can you please provide more info about this.

    6) An other question is when navigating to "C:\ti\simplelink_lowpower_f3_sdk_9_10_00_83\tools\ble\ble_agent\ble_toolbox" and clicking on ble_toolbox we are redirected to 

    Is there a demo explaining how to use this gui.

    Thank you in advance;

    Best regards;

    Hello Ram, 

    1. The RTT calculation will be completed in the source code. The source code is not available to customers. 

    2. We have found some problems with CS on the 9.10 SDK. A new 9.11 SDK will be released at the end of this week. This will fix the problem with invalid distance values. 

    4. The BP-EM-CS boosterpacks are not required for the demo. Without the BP-EM-CS boards, you would need to configure the two boards to use 1x1 antenna paths. To receive BP-EM-CS boards, please reach out to your FAE. 

    5. I have not seen this on my end. The upcoming SDK will have connection handover working properly, if this is a problem with the example project. 

    6. The GUI is not working at the moment. We have been focusing on connection handover, and channel sounding improvements before fixing the GUI. This is mentioned within the release notes. 

    Thanks,

    Isaac
