Sometimes diagnostics report returns with missing information

[MuratUrsavas]

This happened to me couple of times in two days and also seen on @vpetersson's RAK device, too

Also diagnostics return very slow.This might be due to some internal timeouts and could be the source of the missing animal name.

that implies it has not read the ECC key

is there an error message in the logs?

[vpetersson]

We should not report All OK in this state either.

[shawaj]

Weird thing is the ECC is detected (meaning tests have passed?) But no animal name.

Maybe it isn't the ECC but some other bug

[shawaj]

Also how did you get the dark theme on diagnostics @MuratUrsavas 🤔

Didn't know that was possible 😂

[vpetersson]

i mean, there are multiple issues here:

• ECC Detected = True
  • It could be detected perhaps, but not properly provisioned?
• Sync Percentage = 100%
  • Theoretically possible i presume, but seems unlikely if it has no Animal Name
• Animal Name Unavailable
  • This should be unlikely if the ECC has been provisioned
• All OK
  • Clearly not the case given that it has no Animal Name

[shawaj]

It doesn't need an animal name to sync but other than that yeah

[MuratUrsavas]

:smile: @shawaj It is Dark Reader extension (https://github.com/darkreader/darkreader). It works well with 90% of sites. I recommend it.

@shawaj I remember that in some similar reports, the ECC key result was False. So it might be marked as "True" incorrectly in this one. Not checked the logs but will take a look into it.

[MuratUrsavas]

ECC Detected = True It could be detected perhaps, but not properly provisioned?

I don't think this is the case. It was already provisioned in two devices which I've seen.

Sync Percentage = 100% Theoretically possible i presume, but seems unlikely if it has no Animal Name

Again, it is a temporary issue, not caused by ECC provisioning. So it could be 100% at the moment.

Animal Name Unavailable This should be unlikely if the ECC has been provisioned

This is the bug we need to solve but doesn't happen consistently.

All OK Clearly not the case given that it has no Animal Name

The bug could be in our side since Diagnostics is failing to load in timely manner sometimes. So we could be dropping the ball in the process.

[shawaj]

Possibly could be due to another process using the ECC at the time or something? A clash of some sort

[MuratUrsavas]

In normal conditions, it shouldn't be. Because ECC is managed under file system and kernel should be queuing the requests.

[vpetersson]

@MuratUrsavas we've had a long-running hypothesis that we get various ECC related errors due to collisions on the I2C bus. Basically, there is likely a very short lock on the bus when a process is accessing it (unclear if it is both for read and write operations).

[KevinWassermann94]

Would make sense with the occasional ECC errors we have seen.

I have only noticed the animal name unavailable a few times now. The ECC always remained true

@vpetersson if that's the case, we now have to be very careful about that since we'll be opening another channel to ECC.

[shawaj]

Not sure if this is really still a problem at all @KevinWassermann94 @WayneNebra ?
