hello guys, i was just wondering, is there a way to send analog results from the arduino to phone via whatsapp? normally i use a GSM module, but it can be costly at times...i used to use twitter and upload tweets from arduino using the token. just wondering is there any other way..thanks!
Anyone made any progress on this?
An ESP8266 as HTTP client? If you know the WhatsApp API, it is possible. You could use a packet sniffer app to reverse engineer the protocol if it is not publicly available.
