Anthu ambiri amaganiza kuti kulumikizidwa kwa Bluetooth kumangokhala ndi kulumikizana kwapamodzi ndi m'modzi, koma kulumikizana kwamunthu ndi m'modzi m'malo ambiri ogwiritsira ntchito sikungakwaniritse zofunikira, mapulogalamuwa amafunikira kulumikizana ndi ma Bluetooth angapo. Kutsatira monga Feasycom a angapo kugwirizana njira .
Master / Slave maulaliki angapo
Mbuyeyo akuphatikizana ndi akapolo mmodzimmodzi. Kulumikizana kulikonse kumamanga njira. Mbuyeyo amatha kutumiza deta ku njira iliyonse kapena kulandira deta kuchokera ku njira iliyonse. Malumikizidwe angapo sangathe kutumiza deta nthawi imodzi. Mwa kuyankhula kwina, kulankhulana pakati pawo si njira yopititsira patsogolo, ndipo imayenera kulankhulana ndi akapolo osiyanasiyana nthawi zosiyanasiyana potumiza malangizo. Kulumikizana kwakukulu kwa kapolo ndi koyenera kumanga Piconet yaing'ono ndi Scatternet.
Bluetooth mauna
Bluetooth Mesh imapereka njira zambiri zotumizira pakati pazida, ndipo imatha kupanga ma network akuluakulu. Amagwiritsa ntchito ukadaulo wowongolera kusefukira kwa ma network. Deta yotumizidwa ndi node idzatumizidwa ndi node zonse zomwe zimathandizira relay, koma Sizidzatumizidwa kwamuyaya, ndipo node yomwe yatumiza deta sidzayitumizanso. Nthawi yomweyo, Bluetooth Mesh ili ndi njira zina zapadera, monga kasamalidwe ka paketi ya moyo wonse (Time To Live), yomwe imalepheretsanso kutumiza kwa data popanda malire. Bluetooth Mesh ndiyoyenera mayankho a IoT omwe amafunikira zida masauzande ambiri kuti zitumize malo odalirika komanso otetezeka, monga kumanga makina opangira makina ndi ma sensa opanda zingwe.

*BLE 5.2
* Ziphaso za FCC, CE, IC, KC
* Kukula kochepa kwambiri: 10 x 11.9 x 1.8mm
Chiyambi cha ntchito: kuthandizira BLE pakati ndi zotumphukira nthawi imodzi, kuthandizira mpaka 6 kulumikizana (ndi ma module a 6 BLE kapena zida zam'manja) nthawi imodzi, kugwiritsa ntchito mphamvu kumakhala kotsika kuposa 5 mA, kugwiritsa ntchito mphamvu zoyimirira ndi 15 uA (nthawi yowulutsa = 1000 ms).
Zochitika:
1. Kulumikizana pakati pa zida zingapo kumafunikira, monga maloko a zitseko ndi magetsi;
2, Chipata chosonkhanitsira deta kuchokera kuzipangizo zingapo;
Ubwino ndi kuipa: kugwiritsa ntchito mphamvu zochepa, voliyumu yaying'ono ya data, chiphaso chathunthu.

* Realtek RTL8761
* Bluetooth 5.0 wapawiri mode
* Thandizani SPP, GATT, HID protocol
* Liwiro lalitali: 80KB/S(Android), 65KB/S(iOS)
* Makulidwe: 13 x 26.9 x 2.0mm
Chiyambi cha ntchito: Thandizani mbuye ndi kapolo nthawi imodzi, thandizirani maulumikizidwe angapo ndi zida 10 (zida 7 za akapolo za SPP + 3 zida za akapolo za BLE mumayendedwe apamwamba; zida za 7 za SPP + 1 chipangizo chaBLE munjira ya akapolo) nthawi imodzi, kuchuluka kwa data pakati ma modules amatha kufika ku 20 kB / s pamtunda wothamanga kwambiri;
Zochitika:
1. Dongle, pachipata (ayenera kukhala mbuye ndi kapolo nthawi yomweyo, ndipo kuchuluka kwa deta ndi kwakukulu, mosasamala kanthu za kugwiritsira ntchito mphamvu, kusonkhanitsa deta zambiri);
2.Chisamaliro chanzeru;
Ubwino ndi kuipa: kuchuluka kwa data, kuthamanga kwachangu, sikumathandizira kuphatikizika kwakanthawi;

* Thandizani SPP, GATT, HFP, A2DP ndi ma protocol ena
* Kuphatikizika kwa master-kapolo
* Makulidwe: 13 x 26.9 x 2.0mm
Chiyambi cha ntchito: kuphatikizika kwa kapolo-kapolo, kuthandizira kulumikizana kangapo ndi zida za 12 (zida 7 za akapolo a SPP + 5 zida za akapolo za BLE mumayendedwe apamwamba; zida za 7 za SPP + 1 chipangizo cha master BLE munjira ya akapolo) nthawi imodzi;
Zochitika:
1. Dongle, chipata (chiwerengero chambiri, chosakhudzidwa ndi kugwiritsa ntchito mphamvu, kusonkhanitsa deta zambiri);
2. Chisamaliro chanzeru
Ubwino ndi kuipa: audio + data combo module, protocol wathunthu, mtunda wautali wolankhulana (kutumiza kwa data kumatha kufika 250 m, zomvera zimatha kufika 100 m), zoyenera kugwiritsa ntchito mankhwala apamwamba;
