Communicating from iPad to RPi 3 - not over network - Raspberry Pi Forums

-

hi, starting work rpi ths first time, still getting grips things.

i'm developing client run on mac / windows desktop, ipad. needs control multiple uart rs-232 serial devices. rpi proxy accept commands form client, , send them on 1 of 4 attached devices. going write python app listen out incoming serial commands, , forward command relevant device based on data in command. have pi board http://www.pridopia.co.uk/rs-pi-i2c-rs232-4.html

trying work out how send these commands client, work platforms.

have read, direct wifi connection not possible rpi. case?
( can't use network user more on move). leaves wired connection on usb, or wireless on bluetooth.

possible connect rpi serial device on usb? im assuming possible - possible ipad?

possible connect rpi serial device on bluetooth?
again, think there might issues ipad. know apple have mfi programme attached hardware, not option us. bluetooth locked down audio on ipad?

has built ipad app communicates rpi not on local network?

pointers appreciated

configure rpi wi-fi access point, dhcp server , web server. tablet or smartphone can connect that.

Valutazione Template - Joomla! Forum - community, help and support

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!

SD Datastring Convention

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...
