NetBurner Customer Feedback: Why are you using NetBurner?

The excellent out-of-the-box experience

I would like to comment on the quality of a product that I purchased - the MOD5270. I’ve purchased products in the past from

other companies that claim “plug and play” functionality. Usually this means plug it in and try to ﬁgure out why it doesn’t work.

With the MOD5270 I literally plugged in the power, connected it to my router, and ran the factory demo.

I am also impressed with the number of example applications that are included and the fact that all the development tools

are included. It was nice to be able to create a new project, import one of the examples, and run it within 5 minutes.

Keith Gilman, Sr. Design Engineer

The complete hardware and software solution

We did a previous project using different companies for the RTOS, network stack, and compiler. Yeah, three vendors and all the

associated ﬁnger pointing. We had to buy the ﬂash ﬁle system as an extra/add-on. We put an 8M ﬂash device on our proces-

sor bus, and a guy had to write a driver for the device (data register, command register, poll the ready bit, blah, blah), it was a 3+

month job. I thought I was in for the same thing. Thanks to you, we will drop the soldered-on Flash and put on the SD connec-

tor which will be ready to roll with your ﬁle system that runs ‘right out of the box. I was sweating about all the Flash work, and

now its gone.

The active forum ﬁlled with NB Gurus

NetBurner offers a highly versatile and affordable solution set for embedded design, remote control, and product develop-

ment. From the very active user forum (with Netburner gurus in attendance), to the great IDE and tool chain. NetBurner is the

ﬁrst and only solution for TCP/IP-Internet-Web product automation in my book.

Chris Ruff, Software Engineer

The quality of the technical support

I’ve been really impressed with the quality of the tech support. The guys answering the questions are right on and super

helpful (probably has to do with your policy of having the engineers handle the tickets).

Nicolae P. Costescu, Project Engineer

The full-featured tool set, examples, and documentation

The device and the NetBurner tool-set far exceeded our expectations. I spent a week familiarizing myself with the NetBurn-

er tools, and then I wrote a ﬁrst-cut of the original application that I had envisioned for the SB72EX. As it turned out, two of

the example applications formed the core of the networking capabilities of my application. The bulk of my time was spent

implementing a simple command interface to cause the device to interrupt its default IP-to-serial modes to receive and

store a stream of data and then FTP that data to a remote server.

The NNDK interface to the IP/socket facilities of the SB72EX proved to be the simplest part of the application - the inter-

face is straightforward and the documentation is excellent (the large collection of application examples didn’t hurt). Mid-

way through my efforts I had a couple of questions that I elected to send to the NetBurner support group - the response

was almost immediate, the person(s) responding were obviously knowledgeable and experienced - how refreshing!

The SB72EX device and (perhaps more importantly) the NetBurner tool-set have proven to exceed our immediate needs

and have started the gears turning as to how we might use them to address other requirements.
