Hi, folks,
Newbie (to Python) here. I'm porting a Python app from Windows that
talks to a Bluetooth 2.1 device using the serial profile (on WinXP it
shows up as two numbered COM ports, one inbound and the other outbound)
On the Mac, the device shows up in /dev as:
crw-rw-rw- 1 root wheel 18, 7 May 30 23:12 cu.BlueRadios-COM0
On Windows, the app requires me to install pyserial (and pygame for the
visual output).
On the Mac, where I've installed and am using python 2.7.3 (rather than
the pre-installed 2.6.7), my app starts up and acts like it doesn't need
to have pyserial installed, but of course, it can't connect to the
expected numbered COM port.
1. Do I need the Mac equivalent of pyserial?
2. Or can I just stuff something like '/dev/cu.BlueRadios-COM0' in the
app's source code where it expects to open the serial port.
3. Anything special about the Bluetooth serial profile (e.g., setting
port properties)?
Mike
PS: Pointers to the appropriate docs appreciated and I promise to RTFM :-)
Hi Mike,
More than nine years ago there was a mini-wrapper to detect the serial
ports from within Python:
http://mail.python.org/pipermail/pythonmac-sig/2003-February/007189.html
Unfortunately the link is now obsolet.
But there are other prokects still using (extended derivations of) it:
http://trac.warp.es/wader/browser/trunk/contrib/osxserialports/osxserialportsmodule.c?rev=371
https://forge.betavine.net/svn/bcm/branches/sms-confirmation/src/core/contrib/osxserialports/
http://intrepid.danplanet.com/pipermail/chirp_devel/2011-May/000027.html
If this doesn't work for you, drop me a note offline and I will see if I
can find it at home.
The rest is actually using pyserial, which has at least worked for me in
order to connect to serial2USB devices as well as to a GPS via Bluetooth.
