Dears, I got commissioned to develop a prototype for a company, that during last months was already built and tested in many versions.
So they decided to "move" the device in a network system, upgrading the tech level and enabling it with the CoAP protocol (JSON messages replies, with a linux proxy client).
The problem: I am not skilled enough to write a firmware that implements CoAP and ethernet libraries, I am more an hardware engineer, to put it simple.
Moreover, I don't know how to deal with CoAP and I have not enough time to go back to study.
So, the job: I already posted on upwork the job but I'm getting difficulties to find people that knows MCU / embedded firmware design, on AtMel products.
To ease things I described the job about arduino, but seems with no real search improvement. The project can be developed this way too, thus I'm not a fan of it for professional products.
The already made firmware is quite simple, so my idea is to let work an engineer on a completely blank project developing the CoAP structure, later on I will take care to prosecute adding the rest of the classes.
If someone is interested, please PM me, this should be a short project, and of course, I pay.
In case someone of you will accept and want to feel safer, you can join the project on upwork so protection from the organization is offered to both, up to you.
PS: Additional note about hardware: The hardware chosen from the commissioner is an arduino (for prototyping, they loves modular design).
The version used up today were many, the latest prototypes used Arduino Due and Arduino Mega Adk, connected on a custom PCB.
The wiser thing to do is to choose an MCU that is suitable for this hardware, I own the JTAGICE3 so I can download the firmware on this processors. So, the choice is yours for this actual development phase.
Lately I may develop the hardware keeping the processor type or moving on a different one. Another option is the SAM4S Xplained.
