BOOSTXL-AOA: Localisation setup

Hi,

The CC26X2R, in accordance with the BLE spec, provides IQ data and RSSI. The application layer is responsible to extract from the IQ data and the RSSI information regarding the position of the tracked device. The know-how introduced in the application's algorithms is what brings differentiation.TI provides a set of examples (in the SDK), documentation (in the BLE5 Stack User's Guide), labs (in SimpleLinkAcademy on dev.ti.com/tirex/), application notes to assist you. If it was not clear, when it comes to AOA, TI does NOT provide any production ready software.

Best regards,

If I'm right is what you are saying is that there is no application which allows localization, I'd need to setup (at least) 3 master nodes myself for triangulation and trilaturation and make an application which can localize based on the data? 

Hi,

RTLS_UI (please see in in your SDK in tools\ble5stack\rtls_agent\rtls_ui) does pretty much what you are asking for. [Sorry for not mentioning this application before, I thought we already discussed about it in other threads].

One remark on your last message. You will require ONE master, ONE slave and TWO passives. The OOB example does not allow the slave to be connected to several masters at the same time.

I hope this will help,

Regards,

HI clement, 

Can you send a screenshot In the UI I can't seem to find a view that localize an asset e.g track it's location.. I assume I need to configure such software myself. documenation also says in such case "A fourth device is required which is capable of combining the samples from the individual nodes and finding the intersection between the angles" is that correct? 

Hi,

Here is the RTLS_UI (please verify you are using version 1.1.0 of the RTLS_UI [from SDK 4.10]):

On the Space View, you can chose where the CTE RX devices are standing and get a location.

Ferdinandaoa said:

"A fourth device is required which is capable of combining the samples from the individual nodes and finding the intersection between the angles"

This is partially true. The example uses a fourth device (the computer). In a real system, it is possible to use the passive to find the intersection of the angles.

I hope this will help,

Kind regards,

Hi Clement, 

I see! I do use the same version. I was wondering if I can mimic this exact view with the python scripts provided to show a location. does your team have code for this or could you guide me? 

Thank you for the support!

Hi,

We do not share publicly the piece of code you are asking for (and we only provide it inside our RTLS_UI).

You should try to contact your local sales teams to see if they can do something for you. Please note that even with an NDA, I don't guarantee you will have access to this piece of code.

Kind regards,

Hi,

Thank you for contacting me this soon! Can we have The regional sales contact information in The Netherlands?  Also from the user interface can you confirm I am understanding it correctly: 

You are using a master and passive device to gather the AoA, at least looking at the log the Master is gathering an AoA and the Passive is. Do you have a reason you are using the passive in this case? Or is it just for prototyping purposes? 

I understand, thank you for your help!
