'[PIC]: nRF2401 chip experiences?'

I'm thinking about using the single chip, 2.4 GHz
Tranceiver from Nordic Semiconductor to make two
pic talk to each other.

Any experiences with this chip? It's cheap and
by reading the datasheet it seems really great.

I'm having a play with a set at the moment - it's ideal for a project I am
almost working on but external factors seem likely to cancel the project.
They do look to be very useful chips however. I've got samples of the
nRF2401(which I haven't got working yet)  but have also got a loan of the
evaluation kits with the nRf2402 ? - the ones with the 8051 micro included.
Quite a nice evaluation package.

Richard, what kind of prices are the EV kits?  I couldn't find the
info on the website.

Are they available anywhere in small quantities?

You have to contact nordic to get an order form.  The chips are pretty
cheap, but if I recall the ev kit is somewhere around $300.

I asked the local (NZ) agent this yesterday & he said "Something like
$US400" - which was enough to put me off a purchase of the kit unless the
project is definately going ahead.
However it is quite nice,

The type number is nRF24E1-EVKIT

You get :-
PCB with tranciever chip, EEPROM, MAX232, interface pins & power supply for
3.3 or 5-9 Volts
Programmer (USB) dongle for programming the EEPROM or just the RAM (the
8051code runs in ram)
2.4GHz matching network & antennae (1/4 wave)
USB Cables

Note - you get 2 of all the above so you can debug using 2 USB ports - one
for each pcb.


Plus a CD with software & docs.
You can download a limited capability C compiler from Keil Software. It
seems to work quite well (includes simulator) but is limited to 2k
codespace.

Overall the system works very well & if it was better priced I would
definately be looking at getting a couple of kits (I am looking at a mesh
type system with "repeater" capability.)

As far as the actual device samples are concerned, I got a couple from the
local agent but they took a while to get here. You may be able to get them
as samples direct from Nordic.

Is this the chip used in the TRF-2.4G from Laipac?

I have two of these due in today. Here in Australia I can get the
pair for AUS$55. I will let you know how I get on.





Best Regards

It looks similar but is not the same - some of the specs seem to differ
slightly - e.g. +4dBm output  v/s 0dBm out and the frequency range is
different (different channel spacing?). Plus the price seems a lot higher
although you're comparing a packaged PCB against the encapsulated chip.

The evaluation kits ar different again.

On closer inspection of the datasheet - it appears that it is the same chip
- or from the same stable. The users guide appears identical in places. I
wonder how they manage to get 4dBm more output?
Better antennae matching?

That could easily do it.

i got some of the 2.4G modules from lipac (from commlinx in tasmania /
Australia)
no joy getting them running yet, programming the config bits is a little
tricky it seems ;->

if anybody has some JAL source for playing with them (or PIC assembly)
it would be appreciated.

I can send a simple C code test program if that helps (for the Nordic chips
- but the Laipac units seem to be the samechips on a pcb). The interface is
straightforward SPI, but sorting out the configuration words can be the
biggest challenge.
The Nordic documentation seems a bit easier to follow than the commlinx
users guide.
