Problems connecting CP. Port not connected error.

Post by dpdoshi »

Hi Support,

We keep getting port not connected errors on the Circuit Playground classic.

A couple of weeks ago I had placed an order for multiple (5) circuit playground classic for our team here.
Out of the 5 Circuit Playground Classic, there is this 1 circuit playground that has persistent issues connecting to the port.

We have tried it on multiple computers and also ensured that we are using the correct data transfer cable, but only this unit is still not able to detect the port. It keeps saying Port not connected. The other 4 units are working on the same computer with the same transfer cable so we know it is not the cable and not the computer.

I am reaching out to you as well to get a replacement Circuit Playground Classic[ID:3000]

Our Order ID is : 1757507-6275443189

Here is the error:
avrdude: ser_open(): can't set com-state for "\\.\COM3"
An error occurred while uploading the sketch


Thanks,
Dinesh

The microcontroller's USB firmware may have crashed.

Enable verbose messages during upload in the Arduino IDE, connect the Circuit Playground to the computer, and upload a sketch without bothering to select a Serial port. When you see the lines beginning with 'PORTS' start to scroll past in the debug pane, click the Circuit Playground's reset button to force a reboot.

That will make the bootloader set up a new USB connection while the IDE is looking for a device to do just that. That usually gets things working again.

Hi,

I tried the enable verbose messages and then doing the reset while uploading. It still does not work.

Please advise next options.

Thanks.

Post the output from an attempted upload between CODE tags please. Those messages will give us more information about what's going wrong.

That shows no Serial ports at all when it's time for the upload to occur. Does the Circuit Playground's red LED pulse when you double-click the reset button?
