Two questions from you, replies combined here.
We power only through the micro-USB on the Photon board. The 5v then flows through the board to OUR board which has a half dozen IC’s on it and a bunch of resistors and RJ11 telephone connectors. The total current draw is 110ma.
During debugging we almost always power from the laptop. We need the serial output. In the field we run off USB spare batteries. You probably have one - it can recharge a dead iPad or iPhone.
We noted a problem with one type of USB battery: Every once in a while vOut would droop from 5v nominal down to about 4.5v or so. I don’t think that’s what you are talking about. We found these problem batteries because it phantom tripped some voltage comparator circuits on our PC board, erroneously signaling a sensor event.
So enough on volts and amps. You said: “While you can’t connect to the cloud, it’s not so much a cloud issue as you can’t connect to anything at all over Wi-Fi.”
That’s not exactly true. After we found this problem of Cannot Cloud Connect, we tried our system out. The software we flashed into the Photon six weeks or so ago works just fine. That is to say, our Photon listens for a specific socket connection from the laptop. When it gets it, the bidirectional data stream works just fine. So we CAN do stuff over wifi, just not Internet stuff.
The steps to stick in new software apps was real easy. Just the two commands you gave me were needed. Now I need to learn how to load new firmware. If you have a few handy instructions to do that, pass them on!
I said above that our app still works although it cannot cloud connect. One of the keyboard commands we can issue to us is to tell us a ton of status information. Namely, what wifi nets are seen and which we have creds for. Given that our apps DO work, it must be that the creds themselves are not corrupted. However, once I flash 0.4.9 I will check that. It WAS 0.4.9, right? That you wanted?
But having said all that, if there is a deep bug in my stuff or the firmware or the cloud software, I’d expect whatever corruption exists to immediately happen again. Remember, all of our Photons have this problem. (That’s not true, we checked 3 of them and I assume all 6 have the problem.)
Can you tell me when the last automatic download of software took place? Firmware.
Also, do you know when any new cloud software was released. All our junk worked, say, two months ago and now it’s not working. Did something change in Particle-land in that period.
i gotta do other stuff now. I will get back to this either very late tonight or tomorrow. (Friday) Thanks for all the help. I bet you have a full time job over and above customer helper for Particle. I, on the other hand, am retired.
