High-level C++/QML library for Alchemie's Jetting Controller Protocol http://git.tvcloud.fr/cgit.cgi/QtXpl2/atom?h=master 2026-03-13T10:47:00Z 2026-03-13T10:47:00Z Thomas Vanbesien tvanbesi@proton.me 2026-03-13T10:47:00Z urn:sha1:a2b1ccf17845e55caef7f69a5e68f49a55b6a166 Add Xpl2Protocol namespace with buildMessage/parseMessage for wire serialization. Replace raw send/receive API on Xpl2Client with typed protocol methods and internal dispatch. Auto-reply to KA_PING on all sockets (qDebug only). Add GS_JC_VERSION as first typed command with controllerId, firmwareVersion, hardwareVersion, printheadCount properties. Upgrade mock server from echo to line-based command dispatch with 1s KA_PING timer and canned GS_JC_VERSION response. Unknown commands produce qWarning instead of echo. Overhaul demo: remove raw send UI and port config, add wireDebug toggle and Get JC Version button.
