PyS60 Python.Downloads and prerequisites.The Forum Nokia S60 Python homepage contains binaries, links to documentation, Python discussion board, etc. However, it doesn't have the latest release. PyS60 has now a homepage at sourceforge which contains the latest release, documentation, and the sources. Nokia Research Center has a project description for PyS60.Most likely you'll also want to install Python to your PC as well. I use the official release from http://www.python.org/download/.The tools I use for communicating between PC and phone use the PySerial package, which encapsulates access for the serial port. I've tested it on Windows, they claim that it also works on Linux, Mac Os, etc.On Windows PySerial requires win32all extensions. You can test whether you have that by typing import win32com on your Python prompt, if you get ImportError, go to http://sourceforge.net/projects/pywin32/, download, install (now the import should work). If you have installation problems, instructions and FAQ can be found here.Then you can get PySerial here (test it with import serial as above).Finally, the distribution file of these tools. See the changelog to find out what changed when.Tools.Setting up Bluetooth.Bluetooth is nice for communicating between the phone and PC. Not only can you use it to edit python files on PC and sync them to the phone (or any other files such as MP3s, etc.), transfer files (log files, photos, etc.) from the phone to your PC, get a console and shell that uses PC display and keyboard but executes on the phone, you can also use phone to control an application running on the PC. However, different Bluetooth HW and drivers behave differently and are often not straightforward to set up.On my laptop (Windows XP, Wicom BT driver), this is what you need to do. Open Bluetooth configuration, you can find that from the Control Panel.From the Accessibility tab select "Let other Bluetooth devices discover this computer."In the Local Services tab add at least two Serial Services that associate a BT serial connection with a COM port. Select Auto Startup. Give them a name that lets you recognize which COM port the service corresponds to.If you don't have Wicom drivers (which have worked quite nicely for me), you might find something like this under Control Panel -> Bluetooth Devices. Turn the Discovery on and allow others to connect.Then add a couple of incoming serial (COM) ports. As I did this on another laptop, the ports were named automatically (COM5, COM10, etc.).Getting started with sync.Bluetooth console.S60Py has built-in support for a BT console. That is, you use the display and keyboard of your PC while the Python interpreter runs on the phone. Windows comes with Hyperterminal, but that is a horrible tool, I recommend against using that. Based on brief search I found IVT which has worked beautifully for me. Install IVT, start the Telnet version of IVT, choose Serial Transport protocol, select the COM port you've prepared for BT console.From the handset, start Python, select Bluetooth console from the Options menu, find your PC, select the port. If you select your PC / port as default, next time you can start faster.If everything works OK, you should see something like this. Try typing print 'hello' , hit enter. Notice that above the system automatically start pyrepl, which provides better line editing capabilities as in unix readline library, including multi-line editing, emacs key bindings, and command auto-completion (with tab). The pyrepl module is included in the source distribution under the extras directory, you can install that by adding entry ('../../libs/pyrepl', '../libs/pyrepl/*'), to the SYNC_FROM_PC list in sync.config (don't forget to copy the pyrepl directory to ../libs) and running sync. Alternatively, in the distribution I've included PyreplForSeries60.SIS in the pcfiles directory, just send that to the phone and install. I've also extended some rudimentary shell capabilities such as cd, ls, cat, rm, etc. There are also other shell tools for PyS60 available here, but I haven't had time to study them yet.Now you should be all set for Python development. Start sync demon from the PC, keep it listening for a COM port. Start BT console using the second COM port associated with BT. Here's a sample session.First I created a dummy.py file. Calling sync brought it to the phone. The first time you import the module, then you can interactively call its methods. Then I changed the file on PC, re-sync, but you can't import the same module twice in the same session, you have to reload instead.Troubleshooting and tips.Python can't find serial though I just installed it? If you have several Python implementations installed, you may get problems. For example, if you have both the python.org Python, and the cygwin Python, the win32all and PySerial modules will probably install to the python.org Python and be not available in your cygwin Python. The easy solutions include removing cygwin Python or moving your python.org Python earlier in your path. Python on the phone got stuck. If you have a phone model that has a movable cover for the MMC card, you're in luck. Just open the cover (don't even remove the MMC card), all open apps should get killed, close the cover. Restart Python and BT console and continue. Otherwise you may have to reboot the phone. Can't find the PC services from the phone. Sometimes using the stored default connection doesn't work. It seems that both the phone and PC cache some information which gets out-of-date. This is roughly the order in which I try to recover. Don't use the stored default connection, but try searching again for your PC and its services. Kill phone apps (either with MMC cover or reboot phone). Log out of Windows, log in, retry. Reboot Windows. Clever explanations and fixes on this topic accepted. I just changed a file, synched, the changes don't take effect! After the first import, you cannot import a module again, the system notices you already have the module and does nothing. Instead, you have to reload(module) . This also applies to sync, btconsole, etc. If you change those, you either should close phone Python and restart, or do what I d >import btconsole I have another line saying reload(btconsole) . Or what I d >sync() in btconsole.py : I first check with dir() whether the module has been loaded and then choose reload or import. System can't find my module (how do those paths work anyway?). On your BT console, type sys.path . That lists the search paths that Python is using. By default it searches first from the Python installation directory, and then from the /system/libs directories of disks C:, E:, Z: (phone RAM, MMC card, phone ROM). In btconsole.py sync() adds "my" directory to the path in case you put sync.py only there but not to the Python home directory. In general, if you have a module that's only a library (say, phcomm.py), but it to /system/libs (of the disk where you installed Python), if you have a module that can be used directly as a script but can be also a library module to others, you can put it to Python's home (e.g., sync.py), it's in sys.path, import will find it. BTW, there's bt_console.py in Python home. Ignore (delete!) it, what is being used in the Options menu of S60Py for BT console is /system/libs/btconsole.py (both in the standard installation and with these tools).Links.PyS60 tutorial by Jurgen Scheible.
