Hi All,

    Is there a tool or app that shows a visualization of Thread RSSI?

    Any help would be appreciated, thanks in advance.

Hi,

 

nRF Connect for Desktop contains an application called RSSI Viewer, which will display the RSSI for any transmission or noise source. You will need a nRF52 series DK to serve as the receiver though.

Thank you for your reply！

But the RSSI Viewer tool seems to be used only to display BLE's RSSI. 

Or do you know a way to make it display thread's RSSI?

Hi Tao,

 

The GUI notes the BLE channel numbers at the top (37, 00, 01, ...,36, 39), but it will still display any RF signal that the DK picks up, regardless if it is BLE, Thread, Zigbee, WiFi, other protocols or just noise.

 

Best regards,

Hi Andreas,

This tool seems to show the total  signal strength on each channel, how can I know which one is my Thread network? The channel that Thread is in must have wifi signal,because we have a lot of Wi-Fi or Bluetooth in our environment, every channel seems to have a signal.Is that the only way to confirm thread's signal is in the shielding room？

Best regards,

Hi Tao,

 

True, this displays noise as well, so with a lot of noise it will be difficult to know which is your network and not. 

 

You can look at the Thread CLI example as it has similar functions as the OpenThread CLI command list. If that does not do it, you will have to implement RSSI reading of each packet and arrange for this to be reported or displayed as you want, unfortunately we do not have any such tools.

 

Best regards,
