Internet Radio: TTGO T-Display ESP32 with PCM5102 and Annex 1.47.2

[cicciocb]

You are trying to use https:// streams

These require more RAM and your module is not provided with external PSRAM.

Try to flash a firmware without BLE to gain more free RAM

[Pepper]

Thanks, I did use use the BLE Option and emty files.
I now installed the Toolkit 1.1 and new Annex but this does not have the custom config option so i think i have to specify pins used for screen and so on.
Hopefully it will have a couple of bits free ram.

Not sure if this will work.

Hello Pepper.
As has already been discussed in the forum, the problem with Internet stations is that they disappear or change their URL very frequently.
In your case, I would try to remove the security "s" from the https address in your stations. Try this file:

2  Jacaranda=http://live.jacarandafm.com/jacarandahigh.mp3
3  Classica RAI=http://icestreaming.rai.it/5.mp3
4  The 40's sounds=http://81.17.57.158:24929/stream
5  Bosveld=http://iceant.antfarm.co.za/Bosveld
6  Vibe Radio Jazz=http://94.130.242.5:8020/stream
7  Latina=http://start-latina.ice.infomaniak.ch/start-latina-high.mp3
8  Classical 90.5=http://streaming.azpm.org:80/kuat192.mp3
9  Radio Swiss Classic=http://stream.srg-ssr.ch/m/rsc_de/mp3_128

Don't forget to delete the last.dat file or press [Enter] at the end of the last line of the new file.

As for the third station you mention, I don't know what to advise you, since it seems to be a different streaming coding system, which I'm not familiar with.

[Pepper]

Done the stations .txt file thanks - working now...but
What is weird i had to flash the module again, uploaded modified file and all stations are working perfectly even after restarts.

However in my browser(firefox) using editor and editing ONLY a single station name in stations.txt - uploaded it and after restarting some stations does not work anymore including the station name i edited - Stream not open.
Restarting or cycling the power the does not correct it.

Using Annex 1.47.2
Any ideas?

[Fernando Perez]

This may be because the Annex editor treats line endings differently from Notepad.
Also, I've noticed a major flaw in my program: When a station doesn't exist, it stops working without any warning as to why.
For this reason, I have prepared a minimal version, without any flourishes, that you can use to check if everything works perfectly for you before making the final version with the additions you want: VU meter, station information, recording/recovery of the last station heard , etc.
Instead of storing station data in arrays or files, I've used the ancient Basic language method DATA/READ/RESTORE, which gives me an excuse to use ONERROR and study how it works.
In the list of stations, you will see that the third one, Lima Radio, returns an error and how to correct it.
I also advise you to load your module with the version of Annex 1.49.2, which is the one I have used on this occasion; It seems quite stable and with obvious improvements.

Someone thanked me (thanks to you, Bugs) and when I entered this thread, I remembered that I have written a new version of this program; applying the wisdom that comes with years and a thorough study of GUI elements. I have done several checks and tests and it seems robust and stable. It's actually the version I personally use.

And I think I am done, since when I have tried to update my TTGO to Annex versions higher than 1.49.2, everything is problems: Instability, noises and when I try to use it as "Autorun File", it is waiting for data, without sound and without starting the vumeters.
But I don't care, because the way it is now, I'm satisfied.

Remember that when the screen reports that a station has stopped broadcasting and you go to delete the corresponding DATA, also delete the last.dat file. Maintaining it usually doesn't cause problems, but it's better to be safe.
