I have installed FX30_WP8548_full_R17.0.1.007-generic to my FX30s.
Is it possible to modify it so it connects to 3G network automatically (cm data connect) every time it powers on? I would also need to enter an iptables rule so i can access it via SSH over rmnet0.
you can run a unsandboxed legato application to call your script by system() API:
You can write simple Legato application that requests data connection and does not release it.
(later revisions contains much unrelated stuff)
