I will take a look at panstamp.  It certainly is a very good idea, wireless Arduino from the get-go.  I'd be interested to know how the repeater functionality performs.

Hi PaulS,

It means using wireless communications over multiple hops, for example wireless sensor networks.  Imagine deploying Arduino-based nodes for monitoring environmental conditions and sensor data has to be relayed to a base station over several wireless hops.

Hello,

I would like to know if anyone is trying to use Arduino for multihop wireless communications?  If so, what radio modules and software stack have you tried?

Best regards,
Nestor

Hi!  You need to obtain a copy of the Contiki Arduino port and execute the commands below.

Cheers,
Nestor


# Clone contiki-arduino source code tree
git clone https://github.com/contiki/contiki-arduino

# COMPILING AND UPLOADING TO ARDUINO

# To compile the code, e.g., under examples/hello-world
make TARGET=arduino ARDUINO_MODEL=Duemilanove

# To generate hex image file
avr-objcopy hello-world.arduino -j .text -j .data -O ihex hello-world.hex

# To program the Arduino
 avrdude -D -p atmega328p -c arduino -P /dev/ttyUSB0 -b 57600  -Uflash:w:hello-world.hex

# To monitor the serial output
ttylog -V -d /dev/ttyUSB0 -b 115200


with out the contiki.h, normal...

hello-world.c:42:21: error: contiki.h: No such file or directory
hello-world.c:46: error: expected ')' before string constant
hello-world.c:47: error: expected declaration specifiers or '...' before '&' token

then i put the contiki.h in the project folder, and it appears lots of other missing files, that contiki needs...

i need to know is: with contiki in linux:
 
  • how to start a new project?
  • how to compile to arduino
  • how to send to arduino by usb cable, or what software i will use?
