Bug: NRZ-2018-104-B11. No config site before first measure #235

Closed dokape closed 6 years ago

dokape commented 6 years ago

NRZ-2018-104-B11 Testscenario: Restart with power off Sensor Connects wifi. Sensor checks updates, No Update found, Sensor is reachable with webinterface. Startseite/HOME:Fine Values: fine (no values, counting down 145sec) Config-Page: EMPTY (Bug)

Config Page appears after first measure is done and first values are visible.

Connected: SDS011, DHT22, HTU21D, oled and LCD.

Doing more checks: looks like this is not present every test. Try 10 times minimum! I have about 5 times blank site (no error, no waiting of browser) and 5 times Everything fine.

I have noticed this as well. I mentioned it in passing in issue #234, but I wasn't sure whether it was related to the configuration bug I was seeing. It looks like it is a separate issue then. As far as I can tell, it was already occurring in -104-B09, but I don't think it was a problem in version -103.

Okay, I can reproduce this on my test system. Funny enough as there shouldn't be any dependencies to the measurements or the actual time ...

ricki-z commented 6 years ago

It was a memory issue. The config page was too large. What I don't unterstand: the free heap is smaller after sending data (creating strings for last measurements,...). So the blank page should appear after the first measurement if the page is really too large. But it's working now (NRZ-2018-104-B12), so it's only another mystery ...

Should work with new actual release NRZ-2018-105.

@dokape @arouanet can we close this issue?
