[paho-dev] [Help]Sizing architecture

[jerome <jerome@xxxxxxxxxxxxx>]

Hi all,
sorry for any inconveniance but I expect you to help me to choose the 
right MCU for my needs....
Tiny MCUs like Cortex M0+ may come with up to 32kB RAM and 256kb FLASH 
and I would like to know :
- memory footprint for the Eclipse Paho embedded client
- footprint on FLASH once compiled for such ARM chips (without debug 
information)
- library dependencies if I want to activate the AES encyrption support 
(I would like to send all messages from client to back-end using AES 
encryption),

I need to choose the RTOS and I still have some work to do before 
choosing between:
+ FreeRTOS
+ MBed 3(ARM)
+ NuttX
Do you have any success with these RTOS ?
Every input will be useful....

Kind regards
Jerome
