Ntchito ya GSM Location ya ma module a SIM800x ndi ntchito yake ndi Yandex.Locator API

Google, mwatsoka kwa ogwiritsa ntchito ma modules a GSM, miyezi 2-3 yapitayo inatsekedwa ndi kusamutsidwa ku maziko olipidwa API kuti adziwe malo okhudzana ndi makonzedwe a nsanja za selo zowonekera ku module. Chifukwa cha izi, pama module a SIM800 opangidwa SIMCom Wireless Solutions, kugwira ntchito kwa lamulo la AT+CIPGSMLOC kunasiya kugwira ntchito. M'nkhaniyi ndikuuzani momwe mungathetsere vutoli pogwiritsa ntchito ntchito yofanana ndi Yandex - Yandex.Locator.

Tiyeni tidumphe momwe Yandex imalandirira zolumikizira za nsanja zama cell, chachikulu ndikuti titha kugwiritsa ntchito ntchito yaulere iyi ndikupeza zotsatirazi: Latitude, Longitude, Altitude, komanso cholakwika choyerekeza pagawo lililonse. Cholinga chachikulu cha nkhaniyi ndikupereka phunziro lalifupi pakusintha mwachangu ku Yandex API, m'malo mwa ntchito yomwe sikupezekanso kuchokera ku Google.

Pansipa, mwachitsanzo, tidzangowonetsa latitude ndi longitude ya malo a module.

Choncho tiyeni tiyambe

Choyamba muyenera kuwerenga mgwirizano wa ogwiritsa ntchito womwe uli pa: yandex.ru/legal/locator_api. Chidwi kwambiri chiyenera kuperekedwa ku ndime 3.6. mgwirizano wogwiritsa ntchito uyu, womwe umanena kuti Yandex ili ndi ufulu wosintha / kukonza kapena kusintha Yandex.Locator API nthawi iliyonse, popanda chidziwitso..

Pitani ku adilesi yandex.ru/dev/locator/keys/get ndikuwonjezera akaunti yanu ya Yandex yomwe idapangidwa kale kugulu lachitukuko. Masitepewa akuthandizani kuti mupeze kiyi kuti mugwiritse ntchito ntchitoyi.

Lembani kapena sungani kiyi yomwe mwalandira.

Mukamaliza masitepe awa, mudzakhala ndi mwayi wotsegula tsambalo yandex.ru/dev/locator/doc/dg/api/geolocation-api-docpage kumene chidziwitso chofunikira chokhudza momwe ntchito ya Yandex.Locator imaperekedwa.

Kuti mupange pempho la XML mumtundu wa cURL ku Yandex.Locator services, muyenera kupeza zambiri zama cell nsanja "zowoneka" ndi gawo:

• dziko kodi - dziko kodi
• operatorid - nambala ya netiweki yam'manja
• cellid - chizindikiritso cha cell
• lac - kodi malo

Izi zitha kupezeka mu gawoli potumiza lamulo la 'AT+CNETSCAN'.

Zambiri zomwe zalandilidwa kuchokera ku module
