How to install my Tachyon without the cloud connectivity part / cloud integration?

Tachyon

Hi there,

I had received my Tachyon earlier on but wasn’t be able to install it until this week.

I managed to get it online by following the documentation.

Maybe it’s a strange question, but is it possible to install the Tachyon through the default installation without connection it to the Particle cloud platform?

Or do I need to install my customer Ubuntu image for it? And if so, where to start?

Or, which packages need to be removed from the Tachyon in order to disable the cloud connectivity?

My goal is to bring it online without any connection from the outside world.

Thank you for reading.

To answer my own question:

Tachyon installs the following packages:

particle-linux
particle-tachyon-ril
particle-tachyon-syscon

Removing particle-linux removes the connectivity to the Particle cloud.

After that, it still has a connection to a tailscaled IP address.

Disabling and removing the tailscale services finished that. E.g.

systemctl stop tailscaled

apt remove --purge tailscale

Hi Xdeedee2025,

Is the modem still functional after removing all the particle stuff?

This is the output I got, after removing the particle-linux package and rebooting the device.

root@tachyon-xxx:~# particle-tachyon-ril-ctl state
Connected
root@tachyon-xxx:~# particle-tachyon-ril-ctl status
state: 12
signal-quality: 44, true
access-technologies: 13
m3gpp-registration-state: 5
m3gpp-operator-code: XXXXX
m3gpp-operator-name: XXXXXX
cdma-cdma1x-registration-state: 4
cdma-evdo-registration-state: 4
cdma-sid: 0
cdma-nid: 0

So, yes it appears the modem is ok.
