I'll fix it anyway when I next update BBCSDL.
I've now released BBCSDL v0.23a with the fix, although since John has made a change at the server end you probably won't actually see any difference in behaviour in practice - telesoftware downloading should 'just work'. I've also updated the standalone Android client for Telstar, which can be downloaded from here; you may need to enable installing apps from Unknown Sources.

The Telstar client supplied with 'BBC BASIC for SDL 2.0' runs on Windows, Linux, MacOS, Raspberry Pi, Android and iOS.

Telstar now includes national and international weather forecasts on page 290.

Enjoy!

Very nice.

Just a couple of things, the weather description shows the pressure where I am at 1,000 inches! That sounds a little high, the Yahoo Weather page shows it's 1,000 millibars.

Also, on your main menu, you have a small typo in "parliament" - you're missing the 'a'.

Damn those editors :).

Many thanks, I will add the changes to this weekend's deploy.

On request from a user I've updated my 'telstar.bbc' client to allocate much more memory for the downloaded telesoftware (for convenience it downloads to memory rather than directly to a file). You can now download files up to 4 Mbytes or so (there is an MP3 file of that size at CCl4) but you need to be patient because that amounts to more than 11,000 frames! The updated client is in the v0.23b release of BBCSDL.

Just to advise, when googling the 0845 number shown on the holidays page, I came to Balkan Holidays contact page, and they're offering this number for reservations: 020 7543 5555 - can this be changed as 0845 numbers are insanely expensive to call these days compared to landlines or mobiles. (The 0845 130 1114 number is not listed on his page, google seems to imply this is an old number)

Edit: Maybe the entire content is old - the posts have 2012 dates!

The data and numbers comes from the Balkan holidays rss feed. Looks like the feed may be out of date. I may have to withdraw this holiday page. Thanks for letting me know.

More pages updated, more content, system information and some success at accessing the system using Torch Uniview software running under CPN.

Would live rail disruption information be of interest? Possibly, given suitable feeds (and time!!), could expand to a comprehensive road, rail and air travel news section.

Thanks for this.

I did once write an IOS train tracking app using the Network Rail Darwin api, and did think about implementing something. The links you have highlighted may be a simpler way. Time for me to take another look I think.

I am currently working on a new server that can detect incoming data whilst rendering over the same socket stream. This would allow incoming data to interrupt rendering and display the next selected page straight away. This is how Prestel worked and is simple to implement using a serial port, however, it turns out to be rather tricky using TCP sockets. Once I have either built the new server or scrapped it :) , I will look at these feeds.

Many thanks.

May I enquire why, seemingly at least, there is no longer any telesoftware at Telstar (except the trivial Hello World example) that will run on 'modern' BASICs like BBC BASIC for Windows (BB4W) and BBC BASIC for SDL 2.0 (BBCSDL)? The Telstar client that I wrote, and still distribute with every release of BBCSDL, includes a telesoftware decoder having the option of running the downloaded program. This capability is now all but useless, because the sample programs that I had gone to some trouble to adapt to be compatible with BB4W and BBCSDL (e.g. '4INAROW') have been removed.

Sorry, I simply tidied a few things up. The BBC Welcome pack programs are up there. I removed Snap as you said it had an issue, perhaps i misunderstood. I am happy to pop it back.

I will put 4INAROW back also.

Both SNAP and 4INAROW restored (pages 8001131 and 8001132 respectively. If there any more programs you would like to see please let me know. I could have a separate software section for BBC BASIC for Windows/SDL 2.0 rather than lumping it with other BBC programs.

Kind Regards

The latest build (which I'm pretty sure wasn't there yesterday) is rendering completely empty pages for practically all the content.

Tested using both my Brandy-based client and Richard's BBCSDL client on Android.

Thank you, that's greatly appreciated.

You're quite right: neither SNAP nor 4INAROW is perfect. Having to communicate via Darren Storer didn't encourage tweaking (he never revealed who the mysterious 'John' to whom he was forwarding my programs was, I presume it was probably you).
The BBC Welcome pack programs are up there.
True; it may be that some of them would run on a modern BASIC (the only one I tried was POEM but that contains some assembler code - goodness knows why because the version I supply with BB4W and BBCSDL doesn't). Sadly - and I suppose I should take some personal responsibility for this - the original Welcome programs made no allowance for running on a possible future machine with a faster or different kind of CPU. So they contain things like delay loops which now run far too quickly.

Anything you would like to see up on Telstar, just let me know.

Just added an article on creating a Telstar internet modem using an Arduino Uno, Ethernet shield and a MAX232 breakout board. No soldering required!

I even mounted it in a case.

Nice. I assume this is an alternative to using the ESP_modem solutions in the other threads. Or a few of the other wireless serial solutions kicking about.

Is there any advantage to using wire?, or was it more of a 'I did it because I can' type project? Or perhaps going for that more retro box like solution?

Edit: Quite ironic as I have been playing with the ESP sketches over the last couple of days and got them auto configuring and auto connecting to glassy. :)

Yes just another option. I did it simply because I had the parts and it showed that it could all be achieved quite easily without the need for a soldering iron. To be fair it is not the best solution but it works. Having built a couple of the boards by Daniel J. I figured that not everyone would be happy working with such small surface mount stuff and this might be a solution for some.

I would be very interested to hear/see what you have been up to with the ESP etc. sounds awesome.

Will do, oddly enough I was just looking for an easy way to flush the WiFi setting without reflashing or using the esp cmd tool. One thing lead to another.
