Hub RSSI Metric Abnormality

Developers

Over time - I’m seeing a pattern of the Hub RSSI metric being reported back from the Hub with values outside of a normal range.

hub_rssi
hub_rssi930×543 81.1 KB

(I hard limit to zero to visually get around this…)

The raw logs look like this:

{
  "serial_number": "HB-00038302",
  "type": "hub_status",
  "firmware_revision": "169",
  "uptime": 1829032,
  "rssi": 859385398,
  "timestamp": 1619476920,
  "reset_flags": "PIN,SFT",
  "seq": 182734,
  "fs": [
    1,
    0,
    15675411,
    524288
  ],
  "radio_stats": [
    25,
    1,
    0,
    3,
    4248
  ],
  "mqtt_stats": [
    394,
    50
  ]
}
{
  "serial_number": "HB-00038302",
  "type": "hub_status",
  "firmware_revision": "169",
  "uptime": 1829022,
  "rssi": -22,
  "timestamp": 1619476910,
  "reset_flags": "PIN,SFT",
  "seq": 182733,
  "fs": [
    1,
    0,
    15675411,
    524288
  ],
  "radio_stats": [
    25,
    1,
    0,
    3,
    4248
  ],
  "mqtt_stats": [
    394,
    50
  ]
}
{
  "serial_number": "HB-00038302",
  "type": "hub_status",
  "firmware_revision": "169",
  "uptime": 1829012,
  "rssi": -21,
  "timestamp": 1619476900,
  "reset_flags": "PIN,SFT",
  "seq": 182732,
  "fs": [
    1,
    0,
    15675411,
    524288
  ],
  "radio_stats": [
    25,
    1,
    0,
    3,
    4248
  ],
  "mqtt_stats": [
    394,
    50
  ]
}

In this example normal values are like -23, -21, -22, etc. But there will be a crazy value of something like “859385398” that pops into place. (it’s never the same number…)

Sounds like a bug?

Thanks!!

That is a bug. I’ll put it in the bug tracker.

Thanks for the report.

weird as I have 2 hubs for which I logged Rssi and none show such weird values via UDP
You clearly see when I moved them or when not used for some reason.

Just wanted to follow up and share that I haven’t seen this happen since the end of May. So - thank you for the fix!! :slight_smile:
