Meshtastic projekt arendab avatud kommunikatsiooniplatvormi, mis v\u00f5imaldab iseseisva ja detsentraliseeritud s\u00f5numite edastamise v\u00f5rgu loomist, kus iga v\u00f5rgu punkt on seotud naaberpunktidega, ilma kesksete marsruuterite kasutamiseta. Signaali edastamiseks kasutatakse LoRa-protokollil p\u00f5hinevaid vastuv\u00f5tja-saatjaid, mis v\u00f5imaldavad edastada andmeid litsentseerimata sagedusalas kiirusel paar kilobitti sekundis kaugusele k\u00fcmneid v\u00f5i isegi sadu kilomeetreid (Meshtastic kasutajad on seadnud rekordiks 254 km). <\/p>\n

Projekti saab kasutada suhtlemiseks raskesti ligip\u00e4\u00e4setavates piirkondades, otsinguoperatsioonide l\u00e4biviimiseks v\u00f5i spordi harrastamiseks (n\u00e4iteks paraplaaniga lendamine) kohtades, kus puudub infrastruktuur v\u00f5i on kehv mobiilsidekattega. Teatud kohtades saavad osalejad paigutada s\u00f5ltumatud vastuv\u00f5tja-saatjad, mis edastavad s\u00f5numeid ja on toidetud p\u00e4ikesepaneelidest, samas kui osalejatel v\u00f5ivad olla kohalikud LoRa-seadmed, mis edastavad signaale ja mida juhitakse nutitelefonide kaudu Bluetooth-protokolli abil.

\"Meshtastic<\/center> <\/p>\n

Iga v\u00f5rgu osaleja v\u00f5ib saata ja vaadata tekstis\u00f5numeid ning kasutada teisi osalejaid leidmiseks geope\u5b9a\u4f4ding vahendeid, mis p\u00f5hinevad GPS-il. Mesh-v\u00f5rgu loomise t\u00f5ttu edastatakse s\u00f5numid j\u00e4rjestikku, v\u00f5imaldades igal grupi liikmel saada s\u00f5numeid k\u00f5ige kaugemalt osalejalt, s\u00f5ltumata otsese suhtluskanali loomise v\u00f5imalusest. On v\u00f5imalik saata nii laiaulatuslikke kui ka sihitud s\u00f5numeid, mis on suunatud kindlale osalejale. Edastatud s\u00f5numid on kr\u00fcpteeritud eelnevalt valitud PSK (eelnevalt jagatud v\u00f5ti) ja AES256 algoritmi abil. <\/p>\n

\u00dclekande protokoll on piisavalt lihtne: iga pakett saadetakse laiaulatuslikult, p\u00e4rast mida anal\u00fc\u00fcsitakse eeter, et teada saada, kas kinnitust on saanud \u00fcks osalejatest. Kui kinnitust ei ole saanud, tehakse p\u00e4rast kindlat ajavahemikku veel kolm edastuskatset. Paketi vastuv\u00f5tmise korral kontrollitakse, kas see pakett on varem saadetud, ja kui jah, siis j\u00e4etakse see t\u00e4helepanuta; kui ei, siis edastatakse see teistele osalejatele. Iga edastamise k\u00e4igus v\u00e4heneb paketi hop'ide loend ja kui see j\u00f5uab nulli, l\u00f5petatakse paketi edastamine. <\/p>\n

Vastuv\u00f5tja ja edastaja tarkvara on kirjutatud C\/C++ keeltes ja jagatakse GPLv3 litsentsi all. Lisaks on saadaval mobiilirakendused mesh-v\u00f5rgu haldamiseks nutitelefonidest Android ja iOS platvormidel, samuti veebiliides ja Python teek s\u00f5numite saatmise ja vastuv\u00f5tmise automatiseerimiseks. Tarkvara on ette valmistatud erinevate plaatide jaoks, mis p\u00f5hinevad ESP32, nRF52 ja RP2040 kiipidel, nagu 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 SX1262 mooduliga.
