Problem with using a string value for 'radio.setRDSbuffer' in radio.py

[Beun]

Hello,

I realise the code I'm asking about is three years old already, but I still hope you can help me.

Something seems to go wrong if I try to enter a value from a string into radio.setRDSbuffer, in radio.py.

This DOES work as expected:

while True:
        radio.setRDSbuffer( "My own")
        sleep(6)
        radio.setRDSbuffer( "Radiostation")
        sleep(6)

And this does NOT work as expected. RDS stops after the sleep(6) after radio.setRDSbuffer( "Radiostation"):

import requests
while True:
        radio.setRDSbuffer( "My own")
        sleep(6)
        radio.setRDSbuffer( "Radiostation")
        sleep(6)
        nowplaying = requests.get('http://example.com/data.txt').content
        radio.setRDSbuffer(nowplaying)
        sleep(15)

This is the error message that gets displayed in the terminal:

Traceback (most recent call last):
  File "/home/pi/Internet-Radio-Rebroadcaster/radio.py", line 41, in <module>
    radio.setRDSbuffer(nowplaying)
  File "/home/pi/Internet-Radio-Rebroadcaster/Adafruit_Si4713.py", line 749, in setRDSbuffer
    bufferArray[i] = char
IndexError: list assignment index out of range

For the record; opening http://example.com/data.txt in a browser shows the one line of plain text as expected. Also, the below code prints out the contents of the text file to the terminal perfectly. So the retrieving of the text and putting it into a string, and then printing that string works.

import requests
nowplaying = requests.get('http://example.com/data.txt').content
print (nowplaying)

Any idea on how to get a string value into radio.setRDSbuffer, in radio.py?

It looks like this line is the issue.

nowplaying = requests.get('http://example.com/data.txt').content

It may be because it is trying to send it before it has fully downloaded the file. I would make that into a function that you call when you are sending RDS.
