In december my distributor told me, that Wavecom had plans to publish a tool that creates differential patches for DOTA 1 & 2 updates independently from the IDS platform. That is, you don’t have to download your full OpenAT application or a full new firmware to the module, but only the “difference” between your new and your old version, leading to considerably smaller downloads.
Now I just heard from my distributor that all plans to develop the tool are shelved for the time being (developing such a tool would be to much work for now, according to Wavecom).
I find that a real shame, since I would use such a tool rather frequently, be it only to avoid inflicting high bandwidth costs on our customers.
I was wondering how many more people would be interested in such a tool, and whether Wavecom would reconsider its choice if therer were enough.
Another possibility would be if Wavecom published more info on the binary structure of FWs and OpenAT apps, so that customers (like me) could write their own diff patch generator.
