[Bug]: RAK4631 stops updating after a while (and only comes back after any kind of serial connection)

Rak4631

Firmware Version

2.5.15.79da236

Description

Not sure if related to #5491 so I opted to create a new issue to tackle the potential bug separately.

I'm also experiencing some issues with a RAK4631 (i have 2 and one is acting weird).

List of nodes:

• A (esp32), connected to wifi and MQTT
• B (RAK4631), node connected to a Raspberry Pi that I can SSH into. Firmware: 2.5.15"
• C (RAK4631), purely remote node (solar). Firmware: 2.5.18.89ebafc"

I'm in a very low density area and only my nodes are present.

A can see C and somewhat see B. B can see C.

Looking at the meshtastic map, node B stops being updated after a while (some random time). If I ssh into the raspberry and leave a serial connection opened with --noproto, it never stops responding and the "last updated" info in the map is always fresh.

It also seems that triggering any serial connection with the board makes it soft reset and it starts responding again and the map info gets instantaneously updated (by talking to the A node).

1. Requesting telemetry for node B on node A:

meshtastic --request-telemetry --dest '!5570b7aa'
Connected to radio
Sending device_metrics telemetry request to !5570b7aa on channelIndex:0 (this could take a while)
Aborting due to: Timed out waiting for telemetry

2. Node B logs right after starting --noproto:

3. Requesting telemetry for node B on node A after the step above:

meshtastic --request-telemetry --dest '!5570b7aa'
Connected to radio
Sending device_metrics telemetry request to !5570b7aa on channelIndex:0 (this could take a while)
Telemetry received:
Battery level: 101.00%
Voltage: 4.28 V
Total channel utilization: 3.15%
Transmit air utilization: 0.15%
Uptime: 189882 s

If I leave --noproto running on node B (by using the RPi), it never stops responding! (or if I run any command that talks to the node via serial)

Relevant log output

No response

[GUVWAF]

Ignore received packet due to error=-7

and

rxGood=10,rxBad=8

is suspicious. You are receiving quite some corrupted packets. Can you check if that's from only the ESP32 or the other RAK or from both?

Is B only powered by the RPi USB port? What is its role set to and do you have power saving enabled?

is suspicious. You are receiving quite some corrupted packets. Can you check if that's from only the ESP32 or the other RAK or from both?

what's the best to test that?

Is B only powered by the RPi USB port? What is its role set to and do you have power saving enabled?

yes, powered via usb port. Haven't set up any role specifically, just connected it. I have not enabled any power saving setting but will confirm if there's any defaults

[GUVWAF]

what's the best to test that?

Turn one of them off, and try to send packets and see if the error appears. Usually this is caused by an issue with the transmitter, but if it's happening for both it might also be an issue at the receiver.

yes, powered via usb port.

Hmm, I'm wondering if it might be a power supply issue. Maybe it's worth trying to connect it just to mains power and see if the issue persists.

[andrepcg]

Will try to change the power supply (tomorrow).

In the meantime, here's more logs right after running --noproto when the down was down for some time:

[madeofstown]

Just wanted to chime in about the -7 errors - I too see these quite often at my house. I have tried switching radios out and moving positions but they still remain. I'm cueious if these errors can be caused by other protocols using the same spectrum. I do live in a city.

[GUVWAF]

Yes, those errors may also appear e.g. due to interference, packet collisions or when you're at the edge of reception (poor SNR), but when 8/18 received packets are corrupted in a 3-node mesh, it likely indicates a failure somewhere.

@andrepcg Do you have any new results to share?

Literally changed the power source just now. Will monitor the results in the next hours. The only downside is that now I don’t have access to serial via the remote ssh connection so I won’t be able to check debug logs (or reboot the node)

[andrepcg]

@GUVWAF I think it’s working reliably now. Since yesterday the node has been responsive, I can get telemetry fine and chat with it. It may have been a power issue. The raspberry it was connected to also had a ADSB usb device and maybe the power was too much for both. Still weird that it would never fail if the serial connection was kept online

[GUVWAF]

Good to know what the issue was. I'm also not sure why it would not fail if the serial connection was kept alive, but maybe the Pi devotes more current to the port in that case.

I'm still seeing this with 2.5.18.89ebafc. I run a BBS server and it routinely freezes after 12 hours or so. If I then run meshtastic --noproto in another terminal, it leaps back to life and responds again (including to previous messages users had sent to it). If I leave the serial logging running, it's stable for days on end.

My radio is plugged into a power USB hub so that it's not drawing power directly from its companion Raspberry Pi.

[GUVWAF]

At least some power banks are "smart" in a way that they cut the power off when the current draw is too low. Maybe the hub does something similar and keeps it alive when there's activity on the data lines.

[kstrauser]

That’s surely possible. But for posterity, I’ve seen that on 2 different radios attached to 2 different RPis, on any of each Pi’s 4 USB ports.
