Bluetooth mesh

Kutumira mameseji pasina internet, pasina cell sevhisi uye pasina zvivakwa zvechero mutsa. Midziyo iri padyo inobatanidza pamusoro peBluetooth LE uye relay kune imwe neimwe, saka meseji inosvika vanhu vanopfuura redhiyo nekusvetuka nepakati pemidziyo iri pakati.

Peji ino yakaturikirwa nemuchina kuti zvirerukire. ChiRungu chepakutanga ndiyo shanduro inoshanda.

Chii chinonzi mesh

Iyo mesh ndeyechipiri chekufambisa inomhanya padivi pemareyi, kwete yakaparadzana app kana yakaparadzana identity. Zviteshi zveveruzhinji uye meseji yakavanzika zvese zvinoshanda pamusoro payo, uye iyo app inosarudza kuti ndeipi nzira yekutora yega: online inotumira inoenda neinternet uye wodzokera kuBluetooth kana haiwanikwe, nepo wezera achisvikika chete paredhiyo anoramba ari pamambure neimwe nzira.

Inhete yekuparadzira mameseji. Mudziya wekugadzira wese anopa mapaketi kune mamwe mudziya anogona kunzwa, uine muganhururu wekufamba we 7, kubvisa zvakare zvakambotsvaga kuitira kuti paketi isazungunuke nekusingaperi. Vanhu vaviri vasinganzwi zvakanaka zvakananga vanogona kuramba vachitaurirana mameseji kana kuti pane nzira yemidziyo yakabatana pakati pavo.

Pasi pazvo, vaviri vezera rimwe nerimwe vanomhanya a Noise XX kukwazisana uye kutaura pamusoro payo wega encrypted session. Mapaketi akaputirwa uye, kana akakura, akaparadzaniswa, saka saizi yei iwe unotumira inotaura zvishoma sezvinobvira kuti chii.

Chivhutuvhutu chinogona kusvika kumunhu anenge achinzwa panguva iyoyo chete, saka zvinhu zvatatu zvinotakura shoko kupfuura izvozvo: zvishandiso Yeuka nhoroondo yepurikirani yakatsva. uye upe kune uyo asina kukwanisa kuiona, vakuru vakatenderana vari kutakura tsamba dzakavharwa kumunhu asina kusvika mupedyo, uye chero chinhu chipenywa pasina internet ndizvo yakaburitswa panguva inotevera kana internet ichidzoka.

Iyo Nymchat Bluetooth mesh pani, inoratidza mesh chimiro, paired zvishandiso, vezera pane mesh uye redhiyo redhiyo.
Iyo mesh pani: chimiro, paired zvishandiso, vezera vakanzwika, uye mhenyu redhiyo log.

Pa Android uye iOS

Iyo app inomhanyisa ese maBluetooth mabasa kamwechete - kuzvishambadza uye kuongorora kune vamwe - saka chero zvishandiso zviviri zviri padyo zvinobatana zvisinei kuti ndeupi aona mumwe. Grant iyo mvumo yeBluetooth kana yabvunzwa uye inowana vezera iri yega.

Mubrowser

Iyo webhu app inojoinha mesh imwechete kuburikidza neWebhu Bluetooth, paChromium mabhurawuza: Chrome, Edge, Opera uye Brave. PaSafari neFirefox, iyo isingashandisi Webhu Bluetooth, mesh zvidzoreso zvakavigwa zvachose pane kupihwa uye zvazotadza.

Bhurawuza inobatana seshizha

Browser inogona chete kutora Bluetooth nechepakati basa: haigone kuzvishambadza, saka mimwe michina haigoni kuzviwana. Inobatanidza kunze kune mafoni ari pedyo uye inotumira kuburikidza ivo. Iwe unotora mudziyo wega wega kamwechete kuburikidza nebrowser yega mudziyo wekusarudza, wozozviita inobatanidza pachayo. Mabhurawuza maviri haagone kubatana kune mumwe nemumwe zvakananga.

Kugovera mesh neBitchat

Nymchat zvishandiso Bitchat's mesh protocol pawaya, byte yebyte - yakafanana GATT sevhisi uye hunhu UUIDs, iwo musoro wepaketi imwechete, iwo marudzi emeseji mamwe chete, iwo akafanana default hop muganho. Vaviri maapplication haana kuvharwa chero chinhu; vanongori pamambure mamwe chete, uye mudziyo weNymchat uye Bitchat mudziyo vanowana mumwe nemumwe uye kuchinjana encrypted meseji zvakananga.

Kuzivisa mapaketi anogona zvakare kutakura a nostrLink: chinongedzo chakasainwa kubva kune mesh peer kune yavo chaiyo Nostr identity. Kana imwe iripo uye ichisimbisa, shamwari yawakasangana nayo paBluetooth anozviratidza semunhu mumwe chete waunoziva kubva kumarelay.

Mese emashoko akabatwa nevanhu chete

Mugwagwa wevanhu chete ndiko unoburirwa nenzira iyi — mameseji ari kutove anoratidzika kune anumwe zvake ari munjodzi yedhiradio. Mameseji evanhu voga, kubatana kwemashoko uye mamwe akavharwa nehunyanzvi haasati apo.

Mabhuku anotorwa nevamwe vanhu

Kana ukaverenga kumunhu asipo munjodzi yehurukuro, hapana ani anogona kupihwa shoko racho. Nymchat inorivira kiyi yemunhu iyeye uye inopa mhando dzakavharwa kune vamwe vashoma vano vari vakaripoteredza. Vanotakura, uye vanoburitsa kana vakaonana nemugashiri.
