Hello,
I’ve been trying to figure this out for a while now and I just cant seem to find an answer. I currently have 8 photon connected to different machines. They take a reading whenever the machine starts and stops. It counts the interval between the start and stop, then publishes that number to a thinkspeak page.
I am having trouble with one in particular, it will constantly disconnect and reconnect to the cloud. The photon has a constant supplied voltage through the Vin pin, and has an external wifi antenna.
Any suggestions or help with this would be greatly appreciated.
This is the code we are running on all of the Photons we have.
/*This application measures the up and down times of the machines throughout Diehl steel.
Signal wiring is as follows:
Green: D2
Yellow: D0
Ground: Left side pad
Vin: Top left pad
