Topic: Mac: Port Stuck on /dev/cu.Bbluetooth-Incoming-Port How do I switch to serial? (Read 3925 times) previous topic - next topic

Hey there,

So if it isn't super obvious from the question, I'm a beginner with Arduino. I've got an 5v Adafruit pro trinket that my mac will recognize but my IDE won't (kind of). I downloaded the additional boards from the adafruit website and the IDE knows which board I have but for some reason I can't switch my port from the /dev/cu.Bluetooth-Incoming-Port. The Serial port option shows up and is clickable but I cannot switch it over. I've tried uninstalling and re-installing the IDE but it comes on to the bluetooth port automatically. How do I fix this?

This board works unlike other Arduino compatible boards because it bit-bangs USB instead of using a USB serial chip. Read Adafruit's tutorial and if it still does not work, try their support forum.

MAXOSX : how to find out which port /dev/## , the USB use




You have to find out if the connection is made :/dev/cu.usbserial#, /dev/tty.usbserial#.

You need to use /dev/tty.usbserial# instead of /dev/tty.Bluetooth-Incoming-Port.
Most probably your driver is not installed.
Do you find it the terminal? ls /dev/tty.<tab>.
If yes ignore the rest ... otherwise your driver is most probable missing.




Maybe you can download the driver from the internet, to find out which driver ...


Via command line, you are able to find back the name of the vendor, the ID of the Vendor and product;

Code: [Select]
$ system_profiler
$ system_profiler SPUSBDataType
...

Download and install the driver
In my case I had problems with a usb.serial ttl adapter, just as example
