Asset OTA 592KB limit

Firmware
1

Hi,

Boron/Argon project here with a Nextion display.

From the Asset OTA docs, I read that the max size for an asset is 592KB:

image
image1376×502 15.7 KB

The Nextion binary is ~1MB.

Two questions:

  • is the 592KB limit still there?
  • IF that limit is still there, what are the chances that I can split the file in half so it fits this asset ota requirement, and concat them on the internal filesystem of the device before consumption?

Thanks!

Hi Gustavo,

  1. Is the 592kB limit still there? Yes, however, keep in mind that limit is for a compressed asset, not the uncompressed version. You can use something like gzip asset.bin to see a rough comparison of what our bundle CLI command would do (our compression happens in the Cloud so gzip is the closest local equivalent)
  2. What are the chances that I can split the file in half so it fits this asset ota requirement, and concat them on the internal filesystem of the device before consumption? Yes, that should be doable. As long as the assets are within the total asset size limit + every individual asset is under the single asset size, it should work out.

Hope this helps!
