Gyeonghwan,
Unfortunately, the smaller size will likely be an issue. I published a breakdown of the flash previously on the mailing list. We have not moved to memory pools and as you probably already know, heaps (malloc) with this little memory is a real problem.

Thanks for your reply. I heard that Arduino Uno has less hardware capability than both Mega 2560 and Due. Their SRAM size and flash size are more than Uno's ones. * SRAM size: Uno 2KB vs. Mega2560 8KB, Due 8KB * Flash size: Uno 32KB vs. Mega2560 256KB, Due 512KB I am worried that Uno's small SRAM size and flash size are not enough to accommodate IoTivity software stack(of course, constrained devices version). Could IoTivity 0.9.0 be squeezed into Uno's 2KB SRAM and 32KB flash memory? It may depends on the type of application running on Arduino, but I wonder if common code of IoTivity for Arduino requires more than the capacity of Uno.

Our support statement only means that these are the two boards that we developer against, test and have example code for. It does not mean that it will not work on other boards.

IoTivity official site says that it supports only Arduino ATMega 2560 and Arduino Due, but I want to run this on my own device. Is there any way to build or port on Arduino Uno U3? Thank you.
