+title: Meshtastic på SEC-T
+date: 2025-09-10
+---
+SEC-T är en av Europas största säkerhetskonferenser som äger rum i Stockholm varje år. Konferensen samlar cybersäkerhetsexperter, forskare och entusiaster från hela världen för att dela kunskap och diskutera de senaste trenderna inom informationssäkerhet.
+
+I år kommer vi att vara på plats med flera workshops kring Meshtastic! Det blir både nybörjarworkshops där du får bygga din första Meshtastic-nod, och mer avancerade workshops för de som vill gå djupare in i tekniken. Ett perfekt tillfälle att lära sig mer om decentraliserad kommunikation och LoRa-nätverk.

+## SEC-T Firmware
+Nedan går det att ladda ner eller flasha firmware med inställningar för SEC-T. Vi har firmware för den enhet som man bygger under workshopen. Har du enhet sen tidigare så kör vi __ShortFast__ som preset under SEC-T.
