Some further information: It seems if I try to set any band above 28, such as
eutran-32 the command fails. This is on a MC7430.
Command
~# mmcli -m 0
--set-current-bands="eutran-3|eutran-5|eutran-7|eutran-8|eutran-18|eutran-19|eutran-21|eutran-28|utran-1|utran-6|utran-9|utran-19|eutran-32"
~# error: couldn't set current bands:
'GDBus.Error:org.freedesktop.libqmi.Error.Protocol.Internal: Couldn't set
system selection preference: QMI protocol error (3): 'Internal''
Debug output:
