We are using 10 mkr1010wifi boards in a class at our high school. We have them all on the same iot account. All set up initially just fine over USB and/or wifi. No router issues, no connection issues at first.
Now every time we try to connect to most of our arduino's, they show as offline, or sometimes even if online they will not allow us to download a new sketch, saying board not recognized or some other error. Dashboards also appear frozen. Is this the ongoing serial port issues that we used to have with the arduino? Do we need to have all of the students download some drivers? I thought since we were working in the cloud app that we would not need to load individual drivers for the boards.
We have some students on macs' some on pc's. All are having the issue except one or two. I also have the issue on my pc no matter which board I try to connect to.
As the boards are connected locally to the PC the driver must be available exactly there. The cloud app cannot provide a driver to your PC (fortunately!!!).
Every PC used to connect the Arduino must have the corresponding driver installed!
Any idea where we could find and download the driver for the mkr1010? Not on the site, and every set of directions says driver not needed and that windows should install them automatically. Are these drivers gone through WHQL process? Included in the windows builds? If not, where do we find them? Not on downloads pages....
I got another reply that said to clear cache and open and close the cloud workspace 3 times.
I haven't used the cloud service before. Could you clarify a few things though.
You mentioned the serial port issue. Are you trying to connect to these boards via serial, not getting data from the serial monitor, are you using serial on an external device and USB at the same time, do serial reads work over USB when attached to a computer, etc.
If you are connecting via WiFi and only one or two connect, could you try connecting only one or two at a time, log them out or disconnect them, and try a different one or two boards. Try to eliminate if it's a max connections issue or something like that.
On the cloud App (and IDE) there are two ways to connect to the board. One is over USB and the other is over wifi. We cannot connect either way. It always shows board as unavailable. When we used to work with the uno, we would always get a connection issue as the pc or mac would lose the serial port every time the board was disconnected then reconnected, regardless of whether the driver was installed.
We had a max connection issue once and resolved it by purchasing their plan for a year which supposedly allowed for many connections at a time. I think clearing the cache every time we log on, coupled with resetting the board multiple times does it. Still some things to work out with this build!! Seems the arduino folks have some driver work to do!
What are you trying to do with the boards? What do you have attached to them and can you provide schematics and/or pictures? If you have something on a communication line, reset pin, etc., it could also be causing issues.
Which plan did you purchase? I'm not aware of any max connections limitation. Did you really try that with the IDE? If you have connection problems there, then the problem is in your OS, not on the Arduino side.
