How to connect a device to an external battery and also obtain CIR using a QM33120WDK1 Development Kit

Hi everyone!

I’ve been looking for a while for a configuration that would allow me to get the CIR and have the separate computers without connecting to the same PC.

  • Through the CLI model via command line I have managed to keep one equipment connected to external battery and the other to the PC (configuration I want), but I have not been able to get the CIR out.
  • Through UCI in the Python environment I have been able to get the CIR but not to connect one of them to external battery.
  • I have seen that there is a CLI mode through a working environment called Visual Studio Code but despite saying how to get the CIR it does not tell me if the devices can be separated.

The mode that interests me most for my measurement campaign is the CLI via Teraterm, because having the tag connected to battery is much more convenient for NLOS measurements between rooms.

In the manual of this configuration it says that through the ‘DIAG 1’ command we can obtain extra diagnostic parameters such as RSSI. In fact it says: “RSSI calculations make use of IPATOV, STS1, STS2, and CIR (Channel Impulse Response) parameters.” but it does not specify how to get those parameters used for the RSSI calculation.

Thanks in advance

Hi, this is an interesting question. Does anyone know if there is a configuration that allows recording the CIR without connecting both tag and anchor to the same laptop?
Thanks in advance.

Hi @serramric !

  • Through UCI in the Python environment I have been able to get the CIR but not to connect one of them to external battery.

You can use the CLI version on the device to be connected to a battery/power supply. You will need to match the configuration of the UCI device and define the counterpart role in the CLI device using the “setapp” command.

I don’t think you can get the RSSI parameters in the CLI version, unless you change the project to include that info in the TWR output.

Kind regards!
