Looking for a board or a kit that i can send a signal via wifi to a router and then send that signal back to a smartphone… :think:
I’m using an arduino uno, rn-xv, and xbee breakout board to send a json string containing sensor data to a smartphone via my WiFi router.
And does it communicate with a smart phone via text or app… what will be the range…does it have a sleep mode…
The arduino sends a json string containing sensor data to the client when requested. In my case the client is an app on my windows phone however json is easily consumed by apps written for android and ios smartphones. The arduino connects to my home router via the wifi module and is exposed to the internet. This allows the communication to occur anywhere i can get data service with my smartphone. That’s pretty good range! I am not currently employing any kind of sleep mode.
