I-terminal embedded ye-LORA DTU module_MDL210 yileyo isebenzisa iteknoloji ye-LoRa spread spectrum yokudlulisa idatha engenazingcingo, inika abasebenzisi imo yokudlulisa idatha ecacileyo nengenaprotocol.Udinga nje ukuseta iiparameter ezimbalwa ezilula ukuze ufezekise iindlela ezininzi zokunxibelelana ezifana ne-star networking kunye ne-Mesh network. Kukwakho neendlela ezininzi zonxibelelwano ezifana ne-on-demand, i-broadcast, kunye ne-multicast kwinethiwekhi enye;

I-TTL yonxibelelwano iyabonelelwa, Inethiwekhi yezixhobo zezibuko zemizi-mveliso ezisebenziseka lula, umbane wezixhobo usebenzisa uluhlu olubanzi loyilo lokusetyenziswa kwamandla aphantsi (≤40uA@5V).

Itekhnoloji yeLoRa ngokwayo inobuntununtunu obukhulu bokufumana ireceivity (RSSI) kwaye

i-super signal-to-noise (SNR) kunye netekhnoloji yethu yenkxaso yemodem kunye nokusebenza kwemveliso okuzinzileyo nokuthembekileyo.

Imodyuli engenazingcingo yeLoRa inamandla amakhulu okulwa nokuphazamiseka.

I-MDL210 isebenzisana ne-4G DTU yenkampani yethu, enokunceda ekusekweni kwesango le-LoRa ukuze kufezekiswe ukuhanjiswa kwedatha ekude.

Unxibelelwano losasazo

Phantsi kwenethiwekhi efanayo, isixhobo ngasinye sinxibelelana

Unxibelelwano lwenqaku - Ingongoma

Phantsi kwenethiwekhi efanayo, unxibelelwano olujolise ngqo

phakathi kwazo naziphi na izixhobo ezimbini zinokufezekiswa

Unxibelelwano olusebenzisa izixhobo ezininzi

Phantsi kwenethiwekhi enye, izixhobo esinye okanye ezininzi zinokusetwa njengeqela ukuze kufezekiswe unxibelelwano phakathi kweqela neqela

Ezi ndlela zintathu zokunxibelelana zingadityaniswa kwinethiwekhi enye

Ukongeza ekusebenziseni intambo ye-serial yendawo ukumisela ngokuthe ngqo iiparameter zesixhobo se-MIND LoRa,ikwaxhasa ngaphandle kweengcingoukumisela iiparameter zesixhobo esikude.

Njengoko kubonisiwe kuMfanekiso:

Isixhobo se-A siqhagamshelwe kwikhompyutha ngentambo ye-serial, kwaye isoftware yoqwalaselo lwemizobo enikezelwa yinkampani yethu ingasetyenziselwa ukumisela iiparameter zesixhobo sendawo i-A ngokulula nangokukhawuleza, kwaye iiparameter zesixhobo esikude i-B nazo zingamiselwa ngaphandle kwentambo.

*Ukumisela iiparameters kwimo engenazingcingo, qinisekisa ukuba isixhobo sendawo kunye nesixhobo esikude zikwinethiwekhi efanayo.
