DPU: publishing configuration keeps repeating

CUWB v2.x (Archimedes) UWB-GUI

Hello,

I’m trying out a RTLS configuration and I see the following in the logs

attempting to open default.cfg
unable to open config file: default.cfg

The log just keeps repeating the last line. My configuration is as follows:

{
“anchors”: [
{
“serial”: 16779049,
“x”: 22.5,
“y”: 18.800000000000001,

},
{

“x”: 30.399999999999999,
“y”: 9.4000000000000004,

},

“serial”: 16779047,

“z”: 2
}
],
“lcm_port”: 7667,
“run_host”: true,
“tags”: [
{
“serial”: 16779051
},
{
“serial”: 16777216
},
{
“serial”: 16777216
}
],
“twr_adjustment”: 0,
“x_max”: 1000000,
“x_min”: -1000000,
“y_max”: 1000000,
“y_min”: -1000000,
“z_max”: 10,
“z_min”: -10
}

All of the DWUSBs are running 0.6.9. I currently have all 4 anchors and 1 tag clustered on my desk to debug the configuration. The master is plugged into the laptop.

Is this the expected behavior? I was expecting to see some positional data appear.

Regards,

Neil

Neil,

From the output of your dwusb_gui, it looks like the ACM port was changed from ttyACM1 to ttyACM0 when you ran the network. Have you tried running the dwusb_gui application a second time, verifying that the selected ACM port in the config window is ttyACM1?

I’ve also seen that you were going through the process of updating the firmware on your DWUSBs in another forum post. Are the DWUSBs you are using the devices you updated to firmware 0.6.9.0? If so, then you will need to use the more recent cuwb_server application to control the network instead of the dwusb_gui.

A further consideration is the version of Ubuntu you are running. The older dwusb_gui application does not function properly in Ubuntu 16.04, and only works in Ubuntu 14.04. The cuwb_server application, on the other hand, works in both Ubuntu 14.04 and Ubuntu 16.04. If you use the Archimedes cuwb_server application (v2.,), you must use the more recent Archimedes firmware (0.6.9.0).

I hope this helps!

Thanks,
Kyle
