<\/p>\n

Kompletn\u00ed v\u00fdvojov\u00fd kit se skl\u00e1d\u00e1 z vlastn\u00ed desky SiPy, roz\u0161i\u0159uj\u00edc\u00ed desky, ant\u00e9ny s kabl\u00edkem, zakon\u010den\u00fdm U.FL konektorem a krabi\u010dky.<\/p>\n

Vlastn\u00ed elektronika SiPy je – na to, kolik rozhran\u00ed obsahuje, p\u0159ekvapiv\u011b mal\u00e1. Pro srovn\u00e1n\u00ed velikost\u00ed…<\/p>\n

\"\"<\/a><\/p>\n

… odshora: Raspberry Pi Zero (bez WiFi), Linkit Smart 7688 Duo (WiFi, Linux + Arduino CPU), SiPy (ESP32, WiFi, Bluetooth, SigFox).<\/p>\n

Instalace modulu a celkov\u00e1 mont\u00e1\u017e do krabi\u010dky je velice jednoduch\u00e1 – v\u0161e je perfektn\u011b p\u0159ipraveno a sestaven\u00ed cel\u00e9ho kitu nezabere v\u00edce, ne\u017e p\u00e1r minut i m\u00e9n\u011b zru\u010dn\u00fdm jedinc\u016fm.<\/p>\n

\"\"<\/a>\"\"<\/a><\/p>\n

Po sestaven\u00ed doporu\u010duji nejd\u0159\u00edve aktualizovat firmware, co\u017e je p\u0159ehledn\u011b pops\u00e1no na str\u00e1nk\u00e1ch v\u00fdrobce<\/a>. Pot\u011b\u0161ilo m\u011b, \u017ee podpora je jak pro OS Windows, tak pro Linux a jedin\u00e9, co budete pot\u0159ebovat nav\u00edc je micro USB kabel a dr\u00e1tov\u00e1 propojka.<\/p>\n

\"\"<\/a><\/p>\n

Nem\u00e1 smysl, abych se zde podrobn\u011bji rozepisoval o pr\u016fb\u011bhu aktualizace – v\u0161e je o\u0161et\u0159eno v pr\u016fvodci, kter\u00fd aplikace pro aktualizaci obsahuje. V m\u00e9m p\u0159\u00edpad\u011b (Linux Ubuntu 16.4 LTS) prob\u011bhlo v\u0161e bez jedin\u00e9ho z\u00e1drhelu a na prvn\u00ed pokus. Pro vlastn\u00ed v\u00fdvoj aplikac\u00ed je k dispozici hezk\u00e9 v\u00fdvojov\u00e9 prost\u0159ed\u00ed PymakrIDE, op\u011bt dostupn\u00e9 jak pro Microsoft Windows, tak pro Linux.<\/p>\n

Po po\u010d\u00e1te\u010dn\u00edch „hr\u00e1tk\u00e1ch“ s prost\u0159ed\u00edm, registrac\u00ed modulu do s\u00edt\u011b SigFox a zkou\u0161ce oblig\u00e1tn\u00edho blik\u00e1n\u00ed LEDkou jsem se rozhodl zm\u011b\u0159it spot\u0159ebu – p\u0159ece jen jde o technologii, kter\u00e1 by m\u011bla umo\u017enit provoz i z bateri\u00ed. Pr\u016fm\u011brn\u00e1 spot\u0159eba v\u00fdvojov\u00e9ho kitu se pohybuje kolem 110mA. Tohle tedy zrovna moc m\u00e1lo nen\u00ed, ale pak jsem si uv\u011bdomil, \u017ee v tov\u00e1rn\u00edm nastaven\u00ed b\u011b\u017e\u00ed i WiFi v re\u017eimu AP – mus\u00edm tedy nastudovat ovl\u00e1d\u00e1n\u00ed jednotliv\u00fdch rozhran\u00ed, jejich vyp\u00edn\u00e1n\u00ed a zejm\u00e9na ovl\u00e1d\u00e1n\u00ed ULP procesoru, kter\u00fd modul tak\u00e9 obsahuje a m\u011bl by sn\u00ed\u017eit spot\u0159ebu a\u017e na (teoretick\u00fdch) 25uA. Dokumentace je shrom\u00e1\u017ed\u011bna na str\u00e1nk\u00e1ch docs.pycom.io<\/a> a je opravdu velmi rozs\u00e1hl\u00e1 v\u010detn\u011b p\u0159\u00edklad\u016f a j\u00e1 zat\u00edm nejsem ani v polovin\u011b studia.<\/p>\n
