Hello !
After updating the BCU firmware of my ECSCUBE 2900-2 to 1.008, I can no longer update the BMU. My version is 1.006 and the new one is 1.007. When executing the job, the timeout occurs immediately. I've already opened a ticket to Foxess, but no one has contacted me for about 3 weeks. What can I do ?

What datalogger device/firmware are you using? With my setup I have a W2 datalogger, and there was a 3.13 firmware released for that (and a large number of other devices). After updating to it, I found I couldn't update any firmware (same issue with a timeout). About a week later, FoxESS had pulled the 3.13 firmware and rereleased the 3.12 firmware.

If your datalogger has a different firmware version listed currently, I would look to reflash (even if your version is higher). It might also be worth double checking no other firmware components have been pulled (in case a bug with the BCU firmware prevents an upgrade or similar).

The mesage is: timeout the device is in another Upgradetask
