That did the trick, thank you for the fast response!

Hi,

I have been trying to following the documentation here:
http://stuff.iorodeo.com/docs/potentiostat/getting_started.html

I only have the following two lines in my code:
from potentiostat import Potentiostat
pstat = Potentiostat('/dev/cu.usbmodem3649831')

The first line runs fine but the second line throws the following error:
Traceback (most recent call last):
File "/Users/guest/Documents/Sublime/rodeostat.py", line 3, in <module>
pstat = Potentiostat('/dev/cu.usbmodem3649831')
File "/Users/guest/anaconda2/lib/python2.7/site-packages/potentiostat/potentiostat.py", line 111, in __ init __
self.hw_variant = self.get_hardware_variant()
File "/Users/guest/anaconda2/lib/python2.7/site-packages/potentiostat/potentiostat.py", line 120, in get_hardware_variant
msg_dict = self.send_cmd(cmd_dict)
File "/Users/guest/anaconda2/lib/python2.7/site-packages/potentiostat/potentiostat.py", line 407, in send_cmd
msg_dict = json.loads(msg_json.decode())
File "/Users/guest/anaconda2/lib/python2.7/json/__ init __.py", line 339, in loads
return _default_decoder.decode(s)
File "/Users/guest/anaconda2/lib/python2.7/json/decoder.py", line 364, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/Users/guest/anaconda2/lib/python2.7/json/decoder.py", line 382, in raw_decode
raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

I have installed the iorodeo-potentiostat library using pip and am currently using Python 2.7.14 (although Python 3.5.4 gives me the same error as well). Is there something that I am missing?

Thank you.
