hi

I am using afor SPWF04Sx Wi-Fi module - and am trying to run the example python code provided in the user guide.

I have the SPWF04Sx configured as console 2 (UART and python)

I have created a file called wind.py and copied the code from the WIND example section 5.2 on page 17 of AN49

I have used the command 'AT+S.FSC=wind.py,479' to copy it to the RAM on the SPWF04Sx

I have tried running it by calling 'AT+S.PYTHON=wind.py' but only get the response:

File '2:wind.py', line 1

SyntaxError: invalid systax

I have also tried the basic code in 5.1 and, i have created a one line python file with only print('hello') in it.

This also gets the same SyntaxError error

Any suggestions?

I've also noticed that the CTRL short codes dont work on my system i.e. CTRL-D is not recognised to exit REPL, -and I am unable to use CTRL-E to enter Paste mode. Any ideas on that one?

    File '2:wind.py', line 1

    I think you are facing a copy/paste error. Please paste script into an editor (e.g. notepad++), and check what you are sending to the module.

    This is what I see:

    at+s.python=wind.py

    AT-S.Launching script:2:wind.py

    AT-S.OK:17104:10

    Ciao

    I am already using Notepad++ and there are no cut/paste errors from section 5.2

    I have also tried the code from section 5.1, and this produces the same error.

    Does the cut and pasted code work for you?

    It still doesn't work for me.  I tried editing to format the python with both spaces and TABs, neither works for me.

    Even a 1 line .py file with

    print('hello') 

    doesnt work for me 

    AT+S.FSC=hello.py,16  

    AT-S.OK received   

    AT+S.PYTHON=hello.py

    Traceback (most recent call last):

     File '2:hello.py', line 1

    SyntaxError: invalid syntax

    +WIND:0:Console active

    I have a doubt...

    Are you using STM32 Nucleo as USB2UART bridge?

    I've retried and have changed the TeraTerm settings from just CR - to sending a CR/LF on each TX.

    This has fixed the problem. When I now paste the data, and then re-read it with AT+S.FSP - i get the full file contents as expected and the AT+S.PYTHON commands works properly.

    Thank you for your assistance

    Glad to hear you have gotten this working and that it was a simple fix.  Something to keep in mind, a lot of the uPython functionality isn't working yet (basic stuff works but more 'interesting' WiFi stuff doesn't work).  There will be a firmware update for the modules coming out in the next few weeks.  Make sure to talk to your ST Microelectronics rep to get a copy of this firmware beta.
