Bond Timeout on Firmware Upgrade

solarkennedy · April 27, 2026, 9:48pm

I have a bond bridge that.. I’m not sure, port 80 feels funny.

At first I thought I was breaking it somehow with API queries, ending up with connection refused, but now I think it might be something more fundamental.

But barring that, I was hoping just a firmware upgrade might fix is, esp since I saw https://github.com/ZolibraBond/bond-core/pull/3664 in the v4.27.50 changelog. But fundamentally all my attempts to upgrade the firmware fail (support sent me here).

Removing all oddities about wifi, ios, and android, etc, I’ve decided to use the CLI since it is easier to repro and get logs:

And then if I try it again, then I get the connection refused that I’m used to seeing:

And from there it won’t talk to me again:

$ nc -z -v 10.0.2.4 80
10.0.2.4 80 (http): Connection refused

Something I’m doing is clogging up port 80, even if I don’t do a firmware upgrade, but I was hoping the firmware upgrade would fix it!

Great details! Wonder if @merck has seen this or can repro easily.

solarkennedy · May 1, 2026, 6:04pm

I’ve tried getting logs with:

bond livelog --level debug

But I never see anything?

solarkennedy · May 1, 2026, 10:11pm

I see now that the logs are encrypted

Misc

debug/syslog: fix GET which previously reported broken subsystem verbosity levels; and prevent enabling global trace

Livelog: all livelog connections are now encrypted and no longer work with now only support encryption; prepended bondid; incl crc32

Note that bond-cli livelog feature is not yet updated to support the new encrypted livelog.

I’ll use this update livelog command with --key option, required for v4.12+ firmware by chrismerck · Pull Request #65 · bondhome/bond-cli · GitHub

With that I have a full debug log before I rebooted it:

It is is clear that it is “stuck”, but I don’t see any reason why the Bdownload thread would stop.

Would a rescue reset help? Back up before you do one.

Rescue Reset (Firmware Recovery)

If the Bond Bridge is unresponsive or “bricked” (solid blue LEDs or gray ring), you can try a “rescue reset” to restore the original factory firmware:

Unplug the USB power.
Hold the reset pinhole button.
Plug the USB power back in while still holding the button.
Wait for the light ring to blink white for ~ 5 seconds and then turn solid RED.
Release the button when the light is red.

solarkennedy · May 4, 2026, 8:25pm

I was afraid that you would say that

Yes, a full reset and did work and I upgraded the firmware when I added it back in.

Of course, after doing that (I did a backup+restore of the config, nbd), I eventually figured out that this was happening due to an IP conflict on my network. The other device was ARPing for that IP, took it over, etc.

Problem solved.
