Serial to Xively Bridge

This simple program runs on a PC to allow Arduinos or other embedded devices to read and write Xively feed data. e.g.

Embedded device -> Serial -> PC running serial-xively-bridge -> Network -> Xively

Dependancies

These python libraries need to be installed:

• pyserial
• xively-python

Setup

Create a file called 'api.txt' in this directory. Past your Xively device API key in the file on the first line and save.

Usage

When the program is first run you can select from a list of serial ports or the console as in the input device.

Select serial port to open:
0: /dev/tty.Bluetooth-PDA-Sync
1: /dev/tty.Bluetooth-Modem
2: /dev/tty.usbserial-A1017KVR
3: Console input

Select a port and then the program will start waiting for input

Writing data

The command to write to a feed is

write:FEEDID,DATASTREAMID:DATASTREAMVALUE,DATASTREAMID:DATASTREAMVALUE, ...

e.g.

write:135647615,Temperature:25,Pressure:1014,Humidity:76

Not all the datastreams are required to be in the command. Commands are followed by EOL character.

Reading data

The command to read the latest value of a feed is

read:FEEDID

which will return

DATASTREAMID:DATASTREAMVALUE,DATASTREAMID:DATASTREAMVALUE, ...

e.g.

read:135647615

returns

Temperature:25,Pressure:1014,Humidity:76
