Wifi Connection reduced with 15.7.0 about ai-on-the-edge-device

[SybexX]

As far as I know, nothing has been changed on our part regarding the WLAN implementation.
However, I cannot say whether the update from [email protected] to [email protected] changed the WiFi implementation.

the current rolling with [email protected] for testing:

Thank you very much. So a special version to test: I only need to install the firmware via OTA to test, correct?

[SybexX]

@JensHoRi yes this is for OTA update

[JensHoRi]

O.k., lets see. I updated and was needed to fully configure everything again... :-(
By the way I saw a new parameter called rssi Treshold maybe responible for all the reboots of the device. Turned it off now. First minutes doesn't show a positive effect. Very interesting:

Just installed new with special espressif. But until yet it looks like still same bad connection! Very confusing, because nothing else had been changed (WIFI Routers still same version, same position)

What is the temperature of the ESP, has it increased compared to version 15.4.0?
The ESP may reduce the transmission power because it gets too hot.
With more functions and calculations, the temperature inevitably rises.
My ESP is in a waterproof housing and through the new version the temperature is approx. 5°C higher.

@JensHoRi yes this is for OTA update

@SybexX:
It is very welcome when you try to help. But please be fair to the user and inform upfront that this NOT an original OTA update package because config.ini gets overwritten which results in loosing their complete configuration. So they have at least the chance to backup before using such update packages with identical names but different content.

Temperature is about 10 degrees lower than before. Around 80 Celsius

[SybexX]

80°C seems very hot to me, runs it at 240 MHz?
Mine runs at 53°C and with version 15.4.0 it was 48°C.

[JensHoRi]

Well, I have got 4 devices bought in two orders. The first two are like yours around 45-55 degrees, while the two from the second order always hat been some hotter. The quality of esps is very different. :/

[SybexX]

Do the other two also have problems with the WiFi or only the ESPs that get so hot?

[JensHoRi]

The other are not in a steel cabinet, so in general better wifi. One of them is the hotter one, so that’s just because of the different manufacturer I believe.

[JensHoRi]

I went back to 15.4.0 again. rssi is still better as with 15.7.0, no idea why.

Think I should indead train my eyes and change contacts of ESP to external WiFi adress.

If I'm the only one recognizing wifi issues, you can close this issue.

[SybexX]

If you want you can test this version, for me the RSSI went down from -47 to -42.
However, my Fritzbox has been going crazy lately, so I can't say with certainty whether the improvement is caused by my change or by the Fritzbox^^
