Domestic spread spectrum anti-interference low cost serial port 433M wireless communication module Lora kure UART AD hoc network

Hunhu basa

Kubva pane yakachena yepamusha yakaderera-simba kureba-refu yakapararira spectrum chip PAN3028, kureba kwekutaurirana kureba uye kugona kwekurwisa-kupindira kwakasimba; Kutapurirana kwakachena uye kwakajeka, kuchinjika zvizere kune zvakasiyana zvinodiwa nevatengi; Remote kumuka kuti uwane yekupedzisira-yakaderera simba mashandisiro, akakodzera bhatiri-powered application mamiriro; Tsigira RSSI chiratidzo chesimba kudhinda, inoshandiswa kuongorora mhando yechiratidzo, kuvandudza kutaurirana maitiro uye mamwe maapplication;

Inotsigira yakadzika hibernation. Iyo simba diki yemodule mune yakadzika hibernation ndeye 3UA. Tsigira 3 ~ 6V magetsi ekupa, anopfuura 3.3V magetsi ekupa anogona kuve nechokwadi chekuita kwakanakisa; Dual antenna dhizaini nerutsigiro rweIPEX uye maburi echitambi; Chiyero uye kupararira spectrum factor inogona kugadzirwa zvisina tsarukano zvichienderana neiyo chaiyo yekushandisa mamiriro. Mumamiriro ezvinhu akanaka, kureba kwekutaurirana kunogona kusvika 6 km; Simba rinogadziriswa mumatanho akawanda.

Shandisa Tutorial

Iyo CL400A-100 module ndeye yakachena transparent transmission module inopinda otomatiki transparent transparent mode mushure mesimba-pa. Kana iyo inoenderana paramita yemodule ichida kugadziridzwa uye kugadziridzwa, iyo inoenderana AT command inogona kutumirwa zvakananga (ona AT rairo rakagadzirirwa ruzivo). Iyo module inotsigira matatu ekushanda modhi, anoti general transmission mode, inoenderera yekurara modhi, uye periodic yekurara modhi.

1. General transmission mode:

Dhonza pini yeSLEEP, simba-pairi rinongopinda mune yakajairika nzira yekufambisa, panguva ino module yanga iri mune yakajairika yekugamuchira, inogona kugamuchira isina waya masaini kana kutumira masaini masaini, mune iyi modhi inogona kutumira zvakananga inowirirana AT rairo, iwe. inogona kushandura maparameter emodule (chinja maparameter emu module anogona chete kuitwa mune iyi modhi, mamwe mamodhi haagone kuchinjwa).

2, nguva dzose kurara mode:

Izvo zvinodikanwa kuseta iyo module parameter kuAT + MODE = 0 mune yakajairika nzira yekufambisa, uye wozodzora iyo SLEEP pini kudhonza kumusoro, uye module inogona kupinda inoenderera yekurara modhi. Panguva ino, iyo module inoshandisa yakaderera kwazvo ikozvino, iyo module iri mukudzika kwekurara mamiriro, uye hapana data ichatumirwa kana kugamuchirwa. Kana module ichida kutanga kushanda, pini yekurara inoda kudhonzwa pasi.

3. Periodic sleep mode:

Mune iyo general transmission MODE, isa iyo module parameter kuAT + MODE = 1, uye wodzora iyo SLEEP pini kusimudza, uye module inogona kupinda mu periodic yekurara modhi. Panguva ino, iyo module iri mune alternating mamiriro e hibernation standby - hibernation standby - hibernation. Iyo yakanyanya hibernation nguva ndeye 6S, uye inokurudzirwa kuti isapfuure 4S, kana zvisina kudaro iyo module yekutumira ichave inopisa zvakanyanya. Uye iyo yekutumira module inoda kukosha kwePB kuve yakakura kupfuura nguva yekurara.
