Fick ju backa lite i mitt p\u00e5g\u00e5ende projekt f\u00f6r ett tag sedan. M\u00e5nga steg bak\u00e5t. Ge upp varning faktiskt. S\u00e5d\u00e4r s\u00e5 man m\u00e5ste andas in n\u00e5gra g\u00e5nger innan man orkar forts\u00e4tta. Men ikv\u00e4ll seger. Nu kan nycklar \u00f6verf\u00f6ras s\u00e4kert (n\u00e5ja ingen kan vara 100% s\u00e4ker p\u00e5 det) och enheter kan koppla ihop sig utan att veta vilken wifi kanal som den styrande enheten har. Gott s\u00e5.<\/p>\n\n\n\n

Hittade n\u00e5gon bugg ocks\u00e5 som v\u00e4nnerna i Shanghai l\u00f6ste p\u00e5 en natt med en levererad patch, v\u00e4ntetid som till st\u00f6rsta delen var s\u00f6mn f\u00f6r min del eftersom vi ligger s\u00e5 bra till i skillnad i tidszoner. <\/p>\n\n\n\n

S\u00e5 nu finns en alpha node som har wifi\/MQTT\/VSCP link och beta noder som k\u00f6r r\u00e5 802.11. Beta noder kopplar till alpha noder och till varandra. Alfa-noder till wifi och till beta noder. Med MQTT eller VSCP link kan man koppla ihop s\u00e5dan cluster. Eftersom framear skickas vodare kan man bygga r\u00e4tt stota n\u00e4t. OTA s\u00e5klart f\u00f6r samtliga noder och remote debugging. <\/p>\n\n\n\n

Grundern heter esp-now men en massa \u00e4ndringar och till\u00e4gg. Finns n\u00e4stan ingen dokumentation s\u00e5 en liten utmaning d\u00e4r med. Men open source s\u00e5 in i helvete. <\/p>\n\n\n\n

Och varf\u00f6r ber\u00e4ttar jag nu detta?<\/p>\n\n\n\n

Ja det har jag ingen aning om. <\/p>\n\n\n\n

Godnatt!<\/p>\n","protected":false},"excerpt":{"rendered":"
