Uploading firmware with XMODEM/YMODEM

By mvuilleu, in Programming, september 25,2026.

XMODEM and YMODEM are protocols that enable reliable file transfers over a serial connection (UART). They were designed 50 years ago to improve the reliability of data transfers over analog telephone lines, and one might have expected them to have disappeared completely by now. However, there are still a few specific cases where they are widely used, which is why we have just added native support for these protocols in our serial communication modules.

With 15 years of history, our Libraries page and Tools page are starting to get a little cluttered. While many of these programs are still used by our customers, others are no longer relevant. So we're going to archive some software in a separate section. But don't worry, everything will still be available. Let's take stock of the situation.

From day one, the Yoctopuce documentation has emphasized that the Yoctopuce API for a module and its features are intentionally decoupled, to the point where you can work with Yoctopuce features without having to worry about the module that hosts them. In other words, you don't need to look for a specific module to use any of its features. In fact, it's actually not recommended...

A TypeScript app template project

Building a web application, TypeScript is a clear step forward from JavaScript: its static type system catches a wide range of errors directly in your editor, before the code ever runs. But there is one drawback: browsers don't understand it natively, which means you'll need to set up a few tools...

Improvements to SMS support

By mvuilleu, in Programming and New stuff, march 13,2026.

Nowadays, messages exchanged between cell phones are rarely text messages (Short Message Service, or SMS), as smartphones favor the use of more flexible and secure messaging services. Nevertheless, SMS remains an attractive option as a network-independent validation method, particularly for automated systems. That is why we have recently improved the SMS sending and receiving functionality on the YoctoHub-GSM-4G.
