| − | El xip '''FT232''' ha estat durant molt de temps el xip més comú per convertir d''''USB a UART'''. Fins al punt que se'n van fer còpies pirates. Una actualització del sistema operatiu privatiu Windows va explotar una característica dels xips pirates: els xips pirates tenien el registre d'identificació USB de lectura i escriptura i l'original era tan sols de lectura. L'actualització que va fer Windows provocava l'escriptura d'aquest registre i hi escrivia un zero, que feia que el sistema operatiu ho identifiqués com a concentrador USB i no com a controlador d'UART, fent que el maquinari quedés inservible. A l'any 2014 em vaig veure atrapat amb uns quants Arduino Nano que duien aquest xip pirata i vaig escriure [https://binefa.cat/blog/?p=80 How to recover bricked fake FT232] per a poder-los reprogramar i poder-los fer servir amb sistemes operatius lliures GNU/Linux.

| − | === Programació a la vora (''edge'') ===
| |
| − | L'ordinador a la vora (''edge'') pot ser un ordinador normal, habitualment de poca potència, del tipus Raspberry Pi.
| |
| − | | |
| − | Per a tenir visibilitat externa de la pàgina web servida per la placa IoT-02 (per exemple amb la IP 192.168.1.151:80), ho redireccionarem a un port ( 192.168.1.151:80 --> localhost:5001 )
| |
| − | | |
| − | Per a fer funcionar [https://binefa.cat/training/iot02/ota/edge/simple-port-forwarding.js simple-port-forwarding.js] caldrà haver afegit el paquet '''http-proxy''':
| |
| − | | |
| − | npm install http-proxy
| |
| − | | |
| − | El codi nodejs de redireccionament (suposant que la placa IoT-02 ha adquirit l'adreça IP 192.168.1.151):
| |
| − | var httpProxy = require('http-proxy');
| |
| − | var targetHost = '192.168.1.151';
| |
| − | var portOrigen = 80;
| |
| − | var portDesti = 5001;
| |
| − | httpProxy.createProxyServer({target:'http://' + targetHost + ':' + portOrigen}).listen(portDesti);
| |
| − | | |
| − | Per a fer aquest redireccionador sigui un servei, es copia [https://binefa.cat/training/iot02/ota/edge/myForwardingService.service myForwardingService.service] a la carpeta '''/etc/systemd/system''' o el fem de nou amb un editor:
| |
| − | | |
| − | cd /etc/systemd/system
| |
| − | sudo nano [https://binefa.cat/training/iot02/ota/edge/myForwardingService.service myForwardingService.service]
| |
| − | sudo chmod 755 myForwardingService.service
| |
| − | sudo systemctl daemon-reload
| |
| − | sudo systemctl '''start''' myForwardingService
| |
| − | | |
| − | Per a veure l'estat del servei:
| |
| − | systemctl '''status''' myForwardingService
| |
| − | | |
| − | I per a fer que el servei es posi en marxa al reiniciar l'ordinador a la vora:
| |
| − | sudo systemctl '''enable''' myForwardingService
| |
| − | | |
| − | === Programació al núvol ===
| |
| − | Mitjançant una xarxa virtual privada (VPN) de l'estil [https://www.zerotier.com/ ZeroTier] podem fer que l'ordinador a la vora i l'ordinador al núvol comparteixin la mateixa xarxa.
| |
| − | | |
| − | Suposant que l'ordinador a la vora té la IP 10.242.156.158, podem redireccionar-hi 10.242.156.158:5001 --> localhost:7007 :
| |
| − | | |
| − | var httpProxy = require('http-proxy');
| |
| − | var targetHost = '10.242.156.158';
| |
| − | var portOrigen = 5001;
| |
| − | var portDesti = 7007;
| |
| − | httpProxy.createProxyServer({target:'http://' + targetHost + ':' + portOrigen}).listen(portDesti);
| |
| − | | |
| − | I així tenim accés remot des del núvol, connectant mitjançant l'ordinador a la vora que es connecta a la placa IoT-02.
| |
| − | | |
| − | Per accedir-hi des del navegador, escriviu a la URL:
| |
| − | <nom_de_domini>:7007
| |
| − | Això visualitzarà el que presenta l'ordinador a la vora (la IP és la VPN a l'ordinador a la vora):
| |
| − | 10.242.156.158:5001
| |
| − | Que al seu temps presenta el servei pel port 80 de la placa IOT-02 connectada a la mateixa xarxa local que l'ordinador a la vora:
