Meshtastic projekt arendab avatud kommunikatsiooniplatvormi, et luua iseseisev detsentraliseeritud s\u00f5numite edastamise v\u00f5rk, kus iga v\u00f5rgu s\u00f5lm \u00fchendub naabers\u00f5lmede kaudu, ilma tsentraliseeritud marsruuterite kasutamiseta. Signaali edastamiseks kasutatakse LoRa protokolli baasil t\u00f6\u00f6tavaid saatjaid, mis v\u00f5imaldavad edastada andmeid litsentseerimata sagedusala kaudu kiirusel mitme kilobiti sekundis, ulatudes k\u00fcmnete v\u00f5i isegi sadade kilomeetriteni (Meshtastic kasutajad on seadnud rekordi 254 km). <\/p>\n

Projekt on m\u00f5eldud suhtlemiseks rasketes oludes, n\u00e4iteks otsingut\u00f6\u00f6de ajal v\u00f5i sporditegevustes (nt paraplaaniga lendamine) infrastruktuurita piirkondades v\u00f5i halva mobiililevi tingimustes. Teatud kohtades saavad osalejad paigaldada iseseisvaid vastuv\u00f5tjaid, mis edastavad s\u00f5numeid ja saavad p\u00e4ikeseenergial t\u00f6\u00f6tada, ning osalejatel endil v\u00f5ivad olla kohalikud LoRa-seadmed, mis edastavad signaale ja on \u00fchendatud nutitelefonide kaudu Bluetooth-protokolli kaudu.

Iga v\u00f5rgu osaline saab saata ja vaadata tekstiv s\u00f5numeid ning kasutada geolokatsioonivahendeid, mis p\u00f5hinevad GPS-i seonduvuses, et leida teisi osalisi. Mesh-v\u00f5rgu loomise t\u00f5ttu edastatakse s\u00f5numid ahelana, v\u00f5imaldades k\u00f5igil grupi liikmetel saada s\u00f5numeid ka k\u00f5ige kaugemalt osaliselt, olenemata otsekontakti loomise v\u00f5imalustest. On v\u00f5imalik saata nii aadressilisi kui ka laiaulatuslikke s\u00f5numeid, mis on m\u00f5eldud konkreetsele osalisele. Edastatavad s\u00f5numid kr\u00fcpteeritakse eelnevalt valitud PSK (pre-shared key) v\u00f5tmete ning AES256 algoritmi abil. <\/p>\n

Andmete edastusprotokoll on piisavalt lihtne: iga pakett saadetakse laiemas ringis ning seej\u00e4rel anal\u00fc\u00fcsitakse eetris, kas \u00fcks osalejatest on kinnitus saanud. Kui kinnitust ei saadud, tehakse teatud aja jooksul veel kolm saatmis\u00fcritust. Paketi vastuv\u00f5tmise korral kontrollitakse, kas see pakett on varem saadetud; kui jah, siis ignoreeritakse seda, ja kui ei, saadetakse see edasi teistele osalejatele. Iga edastamise k\u00e4igus v\u00e4heneb paketi h\u00fcppamisel loendur ja kui see j\u00f5uab nulli, peatutakse paketi edastamine. <\/p>\n

Kood vastuv\u00f5tja ja edastaja jaoks on kirjutatud keeltes C\/C++ ja jagatakse GPLv3 litsentsi alusel. Lisaks on saadaval mobiilirakendused mesh-v\u00f5rguga t\u00f6\u00f6tamiseks nutitelefonides Androidi ja iOSi platvormidel, samuti veebiliides ja Python raamatukogu s\u00f5numite saatmise ja vastuv\u00f5tmise automatiseerimiseks. Firmav\u00e4rskendused on ette valmistatud erinevatele tahvlitele, mis p\u00f5hinevad ESP32, nRF52 ja RP2040 kiipidel, nagu n\u00e4iteks RAK Meshtastic Start Kit (RAK4631 nRF52840, RAK11200 ESP32, RAK11310 RP2040), Station G1, LILYGO LoRa T3-S3, Nano G1, HELTEC LoRa V3 ja Raspberry Pi Pico koos SX1262 mooduliga.
