Use these commands to turn off BLE on the UE BOOM 2 speaker. The main reason for doing this is to avoid the battery drain when BLE is always on (even when turning off the device with the power button). This was added as "feature" to make it possible to turn on the speaker, but I want better battery life instead. I have used Fedora 39.

First pair the UE BOOM 2 speaker with the laptop and connect to it. Make sure to replace 88:C6:26:xx:xx:xx with the MAC address of your UE BOOM speaker. This can be found in Bluetooth settings in Fedora.

Note: uninstall the Android or iOS UE Boom App since it will enable BLE again!

Commands:

sudo rfcomm bind 0 88:C6:26:xx:xx:xx 1

# Backup the partsbox database.
# Setup:
# 1. Generate the API key in settings of partsbox.com.
# 2. Store the API by using secret-tool (https://gitlab.gnome.org/GNOME/libsecret/issues):
#    $ secret-tool store --label=partsbox provider partsbox
#    (give the API key as input to password prompt)
curl \
    -H 'Content-Type: application/json' \
    -H 'Authorization: APIKey '$(secret-tool lookup provider partsbox)'' \

If you generate a key pair with ssh-keygen you can, depending on version, get a private key with the header

-----BEGIN OPENSSH PRIVATE KEY-----

This type of key is not compatible with f.ex. jsch and needs to be converted so that it has the header

-----BEGIN RSA PRIVATE KEY-----

They way to convert existing keys is as follows: ssh-keygen -p -m PEM -f yourkeyfile
