RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2012, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. Regardless, there are still lots of great
posts in the archive that ware worth looking at. Below are the old forum threads,
including responses to the original posts. Here is the full original RF Cafe Forums on Archive.org
Our companies ended up with three best choices by
comparing the datasheets and use of avaialble Zigbee
devices (listed without particular
ranking):
Ember EM250/EM260
Freescale MC1321X/MC1320X
UBEC UZ2500/UZ2400
Do you have similar experience?

I am writing SW for Ember EM250 and interested in
exchanging experience with other.
I really like
the 16b XAP2 microcontroller that is embedded on
the EM250.

Have done some work with the Freescale MC13192/3.
Good range. Easiest transceiver I ever took through
a FCC test. Seperate TX and RX ports allows you
to consider adding a PA or LNA. However, the Freescale
HCS08 processors have clumsy sleep modes requiring
external wake-ups. The single chip MC13121X seems
to be just putting the MC13192/3 and HCS08 together
without addressing the shortcommings of the processor.
Datasheets on the Ember EM250/EM260 look interesting.
Does the sleep timer work as indicated? Does the
device retain RAM while sleeping?

Probably the best device in silicon!!!
I
was very skeptical to the XAP2, but now that I've
started using it, I really like it.
Ember has
also built some great and cheap tools to support
it. For my home automation application, we get use
for a 16b uC. I am skeptical
about 8b uC for
Zigbee, man.
EM250=Best Zigbee SoC !!!

Ember EM250 can also be used as a MIMO system due
to its excellent dual rf interface.
You get 7db
better sensitivity, assumingly. We are talking about
better than -100dBm sensitivity, guys.

Could you share how you set up the radio
registers of the EM250 to
do this? I've spent
hours and still have some problems with a similar
MIMI mode. Thanx.

Hey guys,
I've been trying to work with Ember
developer kit (EM250) but i'm not able to do the
communication between sensors and sick. I don't
know how I could save my program in them. Can you
help me?
