I have a GoPiGo 3 and a Raspberry Pi 1 Model B+ (512 MB). I flashed DexterOS onto an SD card following the exact instructions on Dexter’s page. I have a wifi dongle (Edimax EW-7811Un according to its instruction manual) plugged in to the pi.
When I plug in with battery or USB, the lights on the Raspberry pi itself light up (and if I experiment by plugging in an ethernet cable connected to my computer, the yellow and green lights by the ethernet light up as well. However, this problem has nothing to do with that as I’m generally not having an ethernet cord plugged in. I only mention it because there’s a video somewhere that says if there’s a problem with your SD card image, those lights next to the ethernet port wouldn’t light up).
On the GoPiGo board, the LED flashes green for a little bit. GoPiGo appears on my PC as a wifi network option. I connect to GoPiGo successfully. The green LED on GoPiGo board stops flashing and starts staying green (however, the little antenna light on the GoPiGo board doesn’t light up at all… the one at the tip of the robot image’s antenna).
I can ping 10.10.10.10 from my PC. If I go to 10.10.10.10 or mygopigo.com, however, it will say “connected to Pi only” (or something very similar to that) in the top left corner and it will say I’m not physically connected to a robot.
I know my pi is talking to the gopigo (at least with power) because if I take the batteries out of the equation and turn it on just with a USB power cord plugged into the pi, the GoPiGo board still has LED’s that light up, so they must be connected.
I tried reflashing the OS, this didn’t help. I tried ordering an SD card from Dexter Industries with the OS already installed (it says v 2.2.0 on the sticker), same problem. I tried reseating the Pi and the GoPiGo onto the pi, same problem.
I have picked up a Raspberry Pi 3 Model B+ from my school’s lab now since it works without a wifi dongle (though I’m aware it might not work “as well” as it would with a Dexter dongle). I won’t have time to try it until late tomorrow (I work nights).
This project is due Dec 3rd and I’m running out of time. I don’t have a USB drive, so I don’t know if that matters (from my understanding it was for updating DexterOS, which mine shouldn’t need, or for storing pictures, which I don’t have a camera, etc). Hopefully I don’t need to physically get any more parts because I’m simply running out of time.
What could possibly be causing this issue? I recognize that perhaps plugging in this Pi 3 B+ might solve the issue, but I was hoping to get somebody thinking on it one day earlier rather than waiting until tomorrow only to find that didn’t help either.
