Connection Setup

Development Tools IDE 1.x

Hey guys,

I feel like I'm making progress here. I'm fighting to connect to a feather bluefruit for the first time. I'm currently getting the following error:
avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied

I've followed the details in the link below and run a "sudo chown [username] [port]" command.

I've also installed the feather 32u4 boards and updated to the latest version of arduino.
I'm running a Ubuntu system.

Any help you can provide would be appreciated!

Try running this command:

sudo apt remove modemmanager

This modem manager program can take over the port of your Arduino board, which makes it impossible for the Arduino IDE to access the port.

It's unlikely you have any need for modem manager, so removing it shouldn't cause any problems.

I got it to work! Turns out I needed to log out of the user, not the arudino application.

Having the modemmanger override seems helpful if it starts locking up. Thanks pert.
