J\u00e1 ale v jednom z projekt\u016f OTA v re\u017eimu AP pou\u017e\u00edv\u00e1m a zat\u00edm (\u0165uk, \u0165uk) jsem na z\u00e1va\u017en\u011bj\u0161\u00ed probl\u00e9m nenarazil. Sl\u00edbil jsem tedy, \u017ee vytvo\u0159\u00edm demonstra\u010dn\u00ed projekt, kde uk\u00e1\u017eu, jak m\u00e1m tento probl\u00e9m vy\u0159e\u0161en\u00fd.<\/p>\n

<\/p>\n

Vyextrahoval jsem tedy jen surov\u00e9 j\u00e1dro, kter\u00e9 \u0159e\u0161\u00ed nastaven\u00ed modulu do AP re\u017eimu a OTA \u010d\u00e1st a cel\u00e9 jsem to doplnil jen p\u00e1r lad\u00edc\u00edmi v\u00fdpisy.<\/p>\n

P\u0159i OTA v AP postupuji takto:<\/p>\n

P\u0159elo\u017e\u00edm projekt a (pokud je to poprv\u00e9 s „\u010dist\u00fdm“ modulem) nahraji jej po s\u00e9riov\u00e9m portu do za\u0159\u00edzen\u00ed.<\/p>\n

Pak po restartu modulu p\u0159ipoj\u00edm PC k nov\u00e9mu AP (viz. obr\u00e1zek v z\u00e1hlav\u00ed \u010dl\u00e1nku). D\u016fle\u017eit\u00e9 je si uv\u011bdomit, \u017ee IP adresa s\u00edt\u011b, kterou poskytuje AP, vytvo\u0159en\u00fd z ESP8266 je v rozsahu 192.168.4.X a v \u017e\u00e1dn\u00e9m p\u0159\u00edpad\u011b nesm\u00ed kolidovat se st\u00e1vaj\u00edc\u00ed Ethernet s\u00edt\u00ed v po\u010d\u00edta\u010di.<\/p>\n

V Arduino IDE se pak v n\u00e1stroj\u00edch v polo\u017ece Port objev\u00ed nov\u00e9 za\u0159\u00edzen\u00ed (v m\u00e9m p\u0159\u00edpad\u011b na adrese 192.168.4.1 a se jm\u00e9nem APOTA), kter\u00e9 vyberu (k tomuhle nem\u00e1m screenshot, nebo\u0165 m\u016fj Linux jaksi odm\u00edt\u00e1 po\u0159\u00eddit obr\u00e1zek p\u0159i rozbalen\u00fdch nab\u00eddk\u00e1ch \ud83d\ude41 ).<\/p>\n

No a pak u\u017e postupuji norm\u00e1ln\u011b – p\u0159elo\u017e\u00edm sketch a kliknut\u00edm na nahr\u00e1vac\u00ed \u0161ipku jej pomoc\u00ed OTA nahraji do modulu<\/p>\n

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

Pro jistotu jsem nahr\u00e1n\u00ed ov\u011b\u0159il n\u011bkolikr\u00e1t, p\u0159i\u010dem\u017e jsem s\u00e9riov\u00fdm termin\u00e1lem monitoroval v\u00fdstup na lad\u00edc\u00edm portu.<\/p>\n

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

Cel\u00fd projekt je skute\u010dn\u011b velmi jednoduch\u00fd a je zabalen\u00fd pomoc\u00ed Archivuj projekt v Arduino IDE.<\/p>\n

A na z\u00e1v\u011br tradi\u010dn\u011b pou\u017eit\u00e9 verze:<\/p>\n

OS: Linux Ubuntu 16.04 LTS (nicm\u00e9n\u011b m\u016fj origin\u00e1ln\u00ed projekt nahr\u00e1v\u00e1m i z Windows 7 x64 Professional)<\/p>\n

IDE: 1.6.9<\/p>\n

ESP8266Core: 2.3.0-rc1<\/p>\n

No a projekt ke sta\u017een\u00ed:<\/p>\n
