Python + Xbee - interpreting binary data for analog samples -

-

i've been working on project digi xbee series 2 (zigbee) modules. have python script receives data on coordinator device , saves database. script has been looking , parsing "samples" key in returned data.

i've since bought digi xbee l/t/h sensor (http://www.digi.com/wiki/developer/index.php/xbee_sensors) , have found returns data using "rf_data" key. appears binary. i'm failing able process , read actual values it.

can tell me if can re-program sensor send "samples" key, or how read/convert binary data?

i've been trying this: 

h=struct.unpack('f',response['rf_data'][0:4])[0]

but i'm out of depth knowing i'm doing ;-)

thanks in advance can give....

it's returning i/o sample, described in digi knowledge base article.

the page linked includes formulas converting adc readings temperature, humidity , light readings.

section 3.2 of python-xbee documentation seems imply i/o samples parsed of version 2.1. make sure you're using version, , see if can access adc-1 through adc-3 of i/o sample, , convert readings light, temperature , humidity values.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
