Connecting the Spark Core to internetless WiFi

Hi, I’m working on a project to track when something leaves the vicinity of an area and send an sms message. I’ll make the sms message script in PHP, repeatedly pinging the spark core and sending an sms message with mail() if it gets no response after a set amount of time.

Unfortunately, though, I’m having trouble getting the spark core to work with this. The wireless network I’m connecting the spark core to is not connected to the internet, which I didn’t think would be an issue as long as it can be pinged locally, but I’m having trouble finding its IP address. I used an IP Scanner on the local network, but didn’t see it.

Any help is very much appreciated.


You can attempt to read it using:

As a side note, which you might already know, if you want to run your own firmware an your Cores without inet connection, you either have to set SYSTEM_MODE(MANUAL) /SYSTEM_MODE(SEMI_AUTOMATIC) or run a local cloud server instance on your network, otherwise the Core will block your code until it can call home.
