![]() It no longer has a microphone, so its files are much smaller. The Livescribe 3 uses a different protocol and file format over Bluetooth LE. Livescribe briefly released an Echo SDK, but this was for writing java-based applets that would run on the pen. ![]() For example, srwalter/libsmartpen and dylanmtaylor/LibreScribe include clients and STF parser, and javispedro’s Scribui is another implementation. The STF stroke files are a custom Huffman code-based format that encode strokes as sequences of (x: u16, y: u16, t: i64).Ī few people have had success writing their own clients. For the last firmware I tried, the pen had a couple quirks that violated the OBEX specification, such as requiring a CONNECTION_ID header in every CONTINUE response. The pen acts as an OBEX server, and the desktop application is an OBEX client requesting files such as lspdata?name=. stf stroke files from the pen to the computer. ![]() Livescribe’s original pens, the Livescribe Pulse and Livescribe Echo, used a HTTP-like protocol called OBEX over USB to transfer. Any other products I should consider and possibly recommend instead of the Echo? Any advice would be most welcome. I am having no luck registering for an SDK and the date of the last post to their broken forum is 2015: I could fall back to syncing the pen to Evernote which has a nice API, but no way to record audio synced to the script. Neo Smartpen looked like a viable alternative without the built-in microphone. My question is really two-fold: a) where do I find documentation on how to build such a pen-docker application and b) if finding the Echo SDK is a no-go, what is the best smart pen to develop custom applications for? Similarly shut down this year and the API was taken offline ![]() then there was another dev program with API's for iOSĪnd Android targetting the Livescribe 3 pen, and this dev program was.Its desktop app there was an eclipse based custom IDE for developersīefore the developer program was shut down and SDK completely the pen originally created 'pencasts' that were flash apps through.the pen is still produced but the company behind it has been put out.I have made some investigation and found that I was approached to write an application that automatically extracts and transcribes notes and audio recordings from a Livescribe pen and uploads them to a webapp when the pen is docked.
