• What .bin file are you trying to flash?
• Please provide a screenshot of Info --> System
• Have you tried a power cycle?

[Gerri1]

Same with me too!

The file is uploaded, but then the message appears.

@Gerri1 especially for you I can say that you have the wrong partition scheme. Please read the important upgrade notes on the start page https://github.com/tbnobody/OpenDTU#-important-upgrade-notes-

Your Sketch partition shows just 1.536 kB. With the new partition table (as delivered since March 2023) the size should be 1.920 kB.

[Gerri1]

I had no problems with the updates up to and including v23.10.9! I'll probably have to remove that part.

[tbnobody]

I had no problems with the updates up to and including v23.10.9!

That might be right... Because these firmware images where most propably small enough to fit into the old partitions.

[Gerri1]

Thanks for the info. When I have a lot of time again, I'll flash it again!

Thanks! This solved the issue in my case :)

[Gerri1]

The new FW is now running for me too! 👍😊

I have the same firmware update error with a new AllianceApps OpenDTU Fusion, although it seems to already have a 1,920 kB sketch partition.

This is the first time I try to update the firmware of the device, that I ordered and received just this week.

I am trying to update the firmware through the web interface with this file: https://github.com/tbnobody/OpenDTU/releases/download/v23.11.15/opendtu-generic.bin

Screenshots attached below.

@awarda-rh you cannot just use the opendtu-generic.bin because this bin is compiled with the generic environment while you need a firmware compiled with opendtufusionv2 environment. I don't know (other then compile it yourself) how to get this specific version.

[awarda-rh]

Thanks, @tbnobody , you see I am still a newby in the OpenDTU world.

I did some more digging on github and found this in the OpenDTUFusionDocs:

ATTENTION for pre-flashed boards If you bought an OpenDTUFusion Board that had a pre-flashed firmware, you might lose radio module connection after using the generic OTA image when you OTA for the first time, as the baked-in pin assignments get overridden.

My device currently is using the "OpenDTU Fusion v2 with CMT2300A and NRF24" device profile, see attached screenshot.

I think, I have to perform these three steps to update the pre-flashed AllianceApps OpenDTU Fusion:

1.) Use this file to OTA update the firmware: https://github.com/tbnobody/OpenDTU/releases/download/v23.11.15/opendtu-generic_esp32s3_usb.bin

2.) After the update restore the configuration from this file: https://raw.githubusercontent.com/tbnobody/OpenDTU/master/docs/DeviceProfiles/opendtu_fusion.json

3.) Then I have to select "OpenDTU Fusion v2 with CMT2300A and NRF24" in Settings > Device Manager.

I haven't executed this plan yet. Does this sound like a reasonable plan, or am I still missing something?

[tbnobody]

Bei mir ging heute in Sachen Verbindung nichts🤷🏻‍♂️

1. Hat dieser Fehler nichts mit dem Error on OTA Upgrade zu tun. Öffne bitte in diesen Fällen einen neuen Issue
2. Wurde dieser Fehler mit dem heutigen Update behoben.

[Marc9485]

Scheint behoben zu sein mit dem heutigen update. Danke dir

[3DJupp]

I also experienced this, some times I still have to do the update via VS Code, thats a fix for then. (Partition table was already the new 1920 kB one)

I have a similar issue upgrading the Firmaware OTA. I also get OTA Error HTTP ERROR] Bad Request

I downloaded the latest release v24.6.29 an tried opendtu-generic_esp32.bin.

My Sketch partition is already 1920 kB.

In the console I could not see any log message regarding this error while upgrade:
