No less! The USB communication cannot establish between the calculator and any recent smartphone.
Indeed, InternetCE worked with my old phone and some others that, apparently, were old enough. But with newer phones, the latter briefly detects the calc, but do not start any USB exchange.

This may be due to a too low voltage, maybe the power that the calculator can provide is too low to start an exchange with a phone. Or maybe this is due to a software update between android 5 and at least android 8 that has changed the way a phone starts a USB communication.

A last possibility would be that USB C behaves differently from the old micro USB ports. But this doesn't make much sense as the USB C specifications are fully backward compatible with the old USB cables.

Anyway, if anyone has any clue about this, his help would be very appreciated.

Pretty explanatory, would be nice to be able to use a Wi-Fi dongle instead of an RNDIS device.

Support TLS to allow users to make HTTPS requests.

For now, InternetCE is directly compiled and linked into the user binary. However, InternetCE is getting bigger and bigger (~30Kio), and prevents the user from making big programs.

I understand that LibLoad can't be used with C code libraries, so I'm thinking of a way to use the intermediate .src code generated by the toolchain with LibLoad.

When trying to compile the program i get the a couple of errors:

any idea on how to fix this?
i followed your installation guide (with the help of google translate) from here

Title, i get this error

Do you know about this?

seems tricky re simulating IO/tethering but maybe doable? or possibly there's another similar lib for working with emulators?

• Support DHCP lease duration
• Request relevant information to the DHCP server
• Release the allocated IP in web_Cleanup()
• ?

I saw that an issue like this has already been created and fixed with a commit a few weeks back, but it still won't work for me...

I've tried it with a Pixel 7a with Android 14 and a Galaxy A71 with Android 13 (and both with USB-C) and I can't enable USB-Tethering for either of them. The phones are not the problem, when connected to a PC, the tethering works just fine.

Thanks for any help!

To allow users to implement an HTTP server, send large data, etc.

My phone recently got soft-bricked, and I want to at least set up an ssh terminal, but this doesn't say if I can use anything else. Got any ideas for something I can connect this to?

To be able to make an async HTTP request with a callback.

The program crashes when the USB connection is closed unexpectedly (cable pulled...).

It only happens after the calculator called usb_SetConfiguration(). From that moment, pulling the cable causes the stack to be corrupted.

It seems that it's more of an USBDRVCE issue but still, it would be nice to find a workaround for this.

Awesome project man!

How did you do USB communication? I want to send some data to a rasp pi and basically couldn't.
Do you have tips or solutions?

Many thanks
Sven

The goal is to have a version of InternetCE that works with the v10.2 of the toolchain (the most recent version at the moment).

Pretty straightforward. When connecting the calculator to a host, InternetCE crashes.

In particular, it happens when we connect the calculator to a PC (with a mini USB type B / USB A cable).
