Christian,
- For this it sounds like you want a kind of ‘bootloader’ application running on top of the firmware (in the same way that the normal Open AT application does in case of some form of catastrophic error in the application? There isn’t anything that could stop the application from being updated except for lack of memory where the application has used too much so a new one cannot be loaded but this memory management should be built into your application anyway.
- The short answer is no to use the delta engine it has to be run through the Sierra Wireless server.

Matt
