RTOS/CC2640R2F: RTLS Node Manager

Part Number: CC2640R2F
Other Parts Discussed in Thread: BLE-STACK

Tool/software: TI-RTOS

Hi, 

We noticed TI RTLS Node Manager was written in Python for PC host and communicate with master and passive device via UART/COM port. In our application, we need to develop our own software to act as 'RTLS Node Manager' in an AOA system. In my case, I need to have a good understanding of how the UART byte array is translated to RTLS commands/data. 

I am not good at Phtyon or Json, so, is there any documents available that explains the uart data format as well as operation flow?

 

Thanks,

TL

    Hi Terry,

    What kind of program would you like to use instead of python? To convert the data from IQ samples to a good position estimate you will have to apply some filters and statistics.

    Did you see the documentation inthe RTLS chapter of the BLE-Stack user's guide? Also you can see the readme file for the RTLS node manager.

    Hi Marie,

    We like to use C sharp, which we already have many controls/classes as well as alforithm and 3D positioning tool developed in the past. 

    Yes, I did read the RTLS user's guide and rtls_agent readme in SimpleLink SDK2.4, however, it seems they are not explaining the command in uart date level. What i like to have is a document that telling the Uart Data. For example, 

    we see the 1st cmd the RTLS Node Manager send to master device is FE 00 00 39 22 1B; where 

    FE could be the command header, 00 00 could be the payload length, 39 --- do not know the meaning, 22 could be the command...

    again, please let me know if there is any document available that explains the transfer data/cmd at UART level.

     

    Thanks in advance,

    TL

    Hi Terry,

    I suggest you read through the uNPI section of our documentation. The whole RTLS Node Manager is built on top of using the NPI interface for RTLS Commands.
    dev.ti.com/.../npi-index.html

    Packet format can be found there.
