[solved] unable to perform Configuration File Backup

Hello Friends,
Easier to say than to do...
I am unable to perform the Configuration File Backup : I tried to follow those instructions ( https://github.com/df8oe/UHSDR/wiki/Backup-and-Restore ) and I ended with :
landsofmordor:Desktop francois$ python uhsdr_tool.py
Traceback (most recent call last):
File "uhsdr_tool.py", line 144, in <module>
backupRestoreApp()
File "uhsdr_tool.py", line 51, in backupRestoreApp
import serial
ImportError: No module named serial
I use a Mac computer, Python 2.7.10 and the mchf cat is working fine with wsjtx (usb cable in the DFU socket).
I am really not a code guy, thank you in advance for your understanding 
Best Regards,
François

Hi Andreas,
Thanks for the clue, it helped to go forward.
For OSX users, I installed pyserial using : sudo easy_install pyserial
Then :
francois$ python uhsdr_tool.py
This program backups and restores the configuration of UHSDR TRX via USB
Use -h to get more information
List of detected UHSDR TRX
[u'/dev/cu.usbmodem1D151']
Please specify valid UHSDR TRX serial port number(!) with -p / --port
so I guessed :
francois$ python uhsdr_tool.py -p /dev/cu.usbmodem1D151 -b
usage: uhsdr_tool.py [-h] [-b] [-r] [-p PORT] [-f FILE]
uhsdr_tool.py: error: argument -p/--port: invalid int value: '/dev/cu.usbmodem1D151'
Closer, but not yet...
ioreg gives this (extract) :
| +-o USB Interface mchf@1d150000 <class AppleUSBDevice, id 0x10000ea57, registered, matched, active, busy 0 (14 ms), retain 22>
| "PortNum" = 5
| "USB Serial Number" = "00000000002A"
and :
ls /dev/tty.usb*
/dev/tty.usbmodem1D151
I am not sure what would be the correct syntax for PORT

Hi Andreas and Friends,
Success !!
Well almost success, I had to do some tweak that Danilo will not approve...
OSX name the usb devices like /dev/cu.usbmodem1D151, so the script do not know how to handle that. I, brutally and inelegantely, hard coded my device name in the script and the backup performed.
Line 88 of the script : " comPort= ("COM" if os.name == "nt" else "/dev/cu.usbmodem1D151")"
As it already exists for the eeprom, could it be possible to add a backup/restore function for the usb key ?
Thanks for helping
Best Regards,
François

Hi Andreas,
You are right about modern language, and thank you for the clean programming.
About the robustness of a backup/restore on key, an intermediary step might be to set an intermediary dialog saying "this is a version x file and you are running a version y code, are you really sure you want to do this ?).
This is absolutely not perfect, bu t this might save a lot of time when testing, experimenting or bug hunting.
Best Regards,
François

Hi Francois,
I think, it should be not a problem to
a) support OSX
b) teach -p to accept full device names.
since b) includes a) we should work on b).
Please replace the line "comPort = ...."
with
try:
int(args.port);
comPort= ("COM" if os.name == "nt" else "/dev/ttyACM") + str(args.port)
except:
comPort = args.port
|
|
Now you can pass full device names as well as numbers (numbers will work only on Linux and Windows).
Please test, report and I'll update the code (or you create a pull request on GitHub).

Hi Danilo,
Thank you for the code, it runs fine. But I needed to change the type of the port argument from int to str (line 66).
Hope that is clean to do that.

Hi Francois,
you're right, then it is a string  .
Good, but the idea works and has the benefit of being compatible with the existing approach.
I will introduce the necessary changes in the code and publish a pull request soon.

I think we can improve here something in the script.
