Get very short distant from Xbee Pro with Duck Antena

Wireless & IoT

Hello, I recently order

2x of XBee 2mW Series 2.5 RPSMA

http://www.sparkfun.com/commerce/produc … ts_id=8692

2x of 2.4GHz Duck Antenna RP-SMA - Large

http://www.sparkfun.com/commerce/produc … cts_id=558

which one mount on XBee Explorer USB

and another one mount on Xbee Shield with Arduino

Once i open the box and i try to read with X-TCU software. but it could fit with old firmware, and i try to write new config with XBP-24B ZNET 2.5

with baud rate 9600

then it can communicate with each other and send data smoothly.

but i try with outdoor and connect between two notebook it can run to only 70 meter !!!

I am Newbiew with Xbee, Please Advice

And one more questions ?

I use Xbee shield but i need to use analog in/out put with i2c, it possible ?

Thank in Advace

see other thread, today’s dates

XBee has no I2C

Does have A/D

The baud rate doesn’t affect range. These are 802.15.4 radios. The wireless link speed is fixed at 250Kbps (raw). This corresponds to about 80-110Kbaud - - IF you don’t use the ZigBee version, IF you don’t use the DigiMesh version, just use 802.15.4 mode with transparent serial ports.

At high baud rates you need flow control as documented: XON/XOFF or RTS/CTS, as in any other “modem”.

Thank man !

No i mean i want to use I2C on Arduino board, but i put the Xbee shield on it would be possible to use I2C signal out from Arduino board to communicate with my other device, not passing thought Xbee

An I2C link from the AVR to some other device seems unrelated to XBee, as XBee doesn’t use I2C. I don’t know the schematic of the “shield” board, but you’d think it leaves I2C untouched, unless there’s a AVR pin-sharing issue with the AVR serial port interface to the XBee.
