Hi,

For POC purpose, i want to know about the DLMS ANSI C stack size for porting into the microcontroller.

Please provide me the stack size of DLMS stack.

Only DLMS Server -> RAM and ROM
Only DLMS Client -> RAM and ROM

This information can help me to decide the microcontroller varients.

Hi,

I can't give that information because it depends on what kind of meter you want to implement and what kind of COSEM objects you want to implement.

On the client side, it depends on what you want to read. If you want to read only the current values, you don't need much RAM, but if you want to update the firmware or read profile generic (historical values) the amount of RAM required is greater.

You need to check what COSEM objects you want to use and then you can check how much memory is needed.

Please atleast give some numbers according to your usages.

i think you also made some projects related to this stack. If you have some data of that project please shared. According to that data i can proceed further.

Hi,

Flash size is from 120 KB to 400 KB. RAM starts from 8 KB. PDU size depends on RAM size and is not critical. The flash size is important. If you want to implement the firmware update multiply the needed flash size by two.

Profile generic (historical data) affects the flash size. If you want to save thousands of rows of data you need more flash.
