also, Iam having the same issues, is there is any techy to solve this or find the reason for the issue.

When you go to the Blynk.Air screen and create a new shipment, are you choosing the correct template then choosing the correct device?

What happens if you choose “no condition” in the “Apply update if this device has…” drop down box?

What happens if you change your new firmware version number to “1.1.2” rather than “1.1.12” then recompiling and exporting the binary file?


I think maybe you don’t use the ESP board versision 3.x.x.

Or you change your new firmware version number, the increment numbering is incorrect. Example: “1.1.1” to “1.1.5”
Should be: “1.1.1” to “1.1.2” ; or “1.1.1” to “1.2.0”

Or, we must wait about 45m for the next shipping/

And now, i think the reason is “you use the same code for the shipping”, i should edit something for make the differrent file size.

This error means your Template Id on the device doesn’t match the uploaded firmware template id.

This check was done specifically to avoid errors when you upload the wrong firmware for the wrong device (we saw it in the wild in the past). In other words - the current OTA doesn’t allow you to change the tempalte id during OTA.

However, I agree that we can improve the message, as it is outdated already. I’ll create internal ticket for the imporvement.
