Gl\u00e4djen. The Droplet Protocol s\u00e4nder och tar emot krypterade och okrypterade 802.11 frames. Mer t\u00e4nk \u00e4n programmering fram hit. Men en bit p\u00e5 v\u00e4g nu. Som vanligt tar det l\u00e4ngre tid \u00e4n man tror. I alla fall f\u00f6r en pension\u00e4r.<\/p>\n\n\n\n

AES-128\/192\/256 krypterade paket skickas normalt mellan noder. Paketen inneh\u00e5ller ett VSCP event och allt utom heartbeat eventen s\u00e4nds krypterat. Namnet droplet<\/strong> kommer sig av att managed flooding som anv\u00e4nds h\u00e4r \u00e4r som ett regnv\u00e4ders droppar p\u00e5 ytan av en sj\u00f6. <\/p>\n\n\n\n

Och nej det h\u00e4r passar inte f\u00f6r h\u00f6gtrafik. Men \u00e4r perfekt f\u00f6r VSCP event som \u00e4r l\u00e4tta och sm\u00e5 som balettdans\u00f6ser. <\/p>\n\n\n\n

Tre niv\u00e5er av noder. <\/p>\n\n\n\n

Alpha<\/strong> – Alltid str\u00f6msatt. Har en wifi koppling. Har en dubbel VSCP tcp\/ip link kanal. MQTT. Webserver. Kan konfigurera andra noder.<\/p>\n\n\n\n

Beta<\/strong> – Alltid str\u00f6msatt. Jobbar bara med droplets. Kan samla paket f\u00f6r sovande beta-noder.<\/p>\n\n\n\n

Gamma<\/strong> – Kan vara sovande. L\u00e5genergi. L\u00e5g niv\u00e5. Jobbar bara med droplets. BLE.<\/p>\n\n\n\n

KISS<\/strong> – Keep It Simple Stupid.<\/em> Ja och det \u00e4r ju det sp, \u00e4r det sv\u00e5ra s\u00e5klart.<\/p>\n\n\n\n

Dumt att bner\u00e4tta det h\u00e4r h\u00e4r s\u00e5klart. Men ibland kan jag inte h\u00e5lla mig. Har ju liksom inga medarbetare h\u00e4r p\u00e5 kontoret som man kan g\u00e5 in till och ropa “HURRA<\/em><\/strong>” hos. Katten bryr sig inte. Ja ingen annan i Los heller antar jag. Troligen ingen i Ljusdal heller. Hmmmm…. Ja och inte den d\u00e4r medarbetaren heller \u00e4ven om man haft n\u00e5gon. Ni vet det d\u00e4r tr\u00f6tta “jaha…<\/em>” man f\u00e5r h\u00f6ra n\u00e4r man sj\u00e4lv \u00e4r euforisk. Men man m\u00e5 ju \u00e4nd\u00e5 f\u00e5 ur sig sina “HURRA<\/em><\/strong>“. Det r\u00e4cker l\u00e5ngt.<\/p>\n\n\n\n

Annars har det varit en mycket tr\u00f6tt dag h\u00e4r. F\u00e5tt k\u00e4mpa en hel del f\u00f6r att beh\u00e5lla koncentrationen. Men nu g\u00e4ller hit men inte l\u00e4ngre. Koden \u00e4r incheckad. Pellets fyllt. Jag \u00e4nnu tr\u00f6ttare. Och jag beger mig d\u00e4rf\u00f6r upp f\u00f6r trapporna f\u00f6r att ta tag i min bok och l\u00e4sa en timme. Allts\u00e5 finns h\u00e4r bara gl\u00e4dje\u00e4mnen i livet just h\u00e4r och nu. Tar man en pepparkaka innan man l\u00e4gger sig s\u00e5 kanske man \u00e4r sn\u00e4ll ocks\u00e5 imorgon. G\u00f6r man det inte s\u00e5 kan man b\u00f6rja ge sig p\u00e5 projektledare igen. S\u00e5 b\u00e4st att ta en. Ja och l\u00e5ta framear flyga medans man sj\u00e4lv sover.<\/p>\n\n\n\n

Godnatt!<\/p>\n\n\n\n

ps<\/strong> Javisst ja. L\u00f6dde ihop det f\u00f6rsta smarta HAN P1 kortet idag ocks\u00e5 eftersom jag \u00e4nd\u00e5 skulle k\u00f6ra ugnen med en till batch av de enklare osmarta korten. Men har inte testat det \u00e4nnu. Det kanske inte alls fungerar. Fast det bor det. Eller? Men f\u00e5r v\u00e4l test adan f\u00f6re julafton. Fungerar det s\u00e5 blir det en bra julklapp. Fungerar det inte. Ja d\u00e5 f\u00e5r man ta nya tag efter julledigheten. Att aldrig ge upp. En hederssak. ds<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
