CHIRP

h1. Connection Issues using Ubuntu

These are not Chirp issues; they are operating system (Linux, Ubuntu) issues. If these notes do not help, get Ubuntu help either through a search or using the Ubuntu support sites.

h2. Symptom with a USB connection

# Click _Radio_ then _Download from Radio_ at the top menu bar; a window appears with Port, Vendor and Model 

# Click Port and from the pull-down list pick the USB option. Usually that is at the bottom of the list with a name like /dev/tty/USB0 

# An error window appears with words like *An error has occured*. 

# Below the error words is something like *Permission denied* 

h2. Symptom with a serial (RS232) connection

# Click _Radio_ then _Download from Radio_ at the top menu bar; a window appears with Port, Vendor and Model 

# Click Port and from the pull-down list pick the serial port (TTY) with a name like /dev/ttyS0. You may have to experiment to find which port number is active. Another common connection is /dev/ttyS4. 

# An error window appears with words like *An error has occured*. 

# Below the error words is something like *Permission denied*

h2. Solution

The most common cause is that the user(s) do not have permission to use the serial-USB connection. Permission must be established for the user. There is much more on this common issue in Linux or Ubuntu wikis and support websites.

# Start a terminal session. 

# Enter this this command into the terminal session: @sudo gpasswd --add ${USER} dialout@ 

# Logout and login again on any sessions you want to see the new group.

# After executing the command, check that it worked with: @groups ${USER}@ 

# The user name will be followed by a list that includes _dialout_. Dialout means permission for the TTY set that includes serial and USB connections.
