I've done this with other RTUs (Remote Terminal Units.) It can get a bit tricky loading and running code on units with different configurations. You must allow for bad downloads and allow the old code to run again. It can get tricky. Utility customers get real pissed if a substation goes down because of a software screw up.

An even nicer advantage is being able to update the code remotely. Your weather station is out in the back forty over a radio link, and you want to record some info about this upcoming storm which will disrupt your radio signal. ie, you won't get the info you want. So you reprogram it over the radio link with new code that will make it act as a datalogger while the storm passes through. No need to go out in the rain. -Adam Ryan Pogge wrote: > > so the advantage is an easy way to update firmware in products, or an easy > way to develop software and reprogram without ISP.... > cool...
