in the meantime, thanks for the support I receive, I am in the evaluation and testing phase (connectivity permitting)
You could always flash the latest snapshot OS together with the package
That said, you could try a couple of things which may or may not work:
- Install the package manually from https://downloads.openwrt.org/snapshots/packages/mips_24kc/packages/modemmanager_1.22.0-9_mips_24kc.ipk
- Follow the official guide to build it yourself
It may turn out that you need too many packages upgraded and it that case upgrading to snapshot OS is probably the only way to go.
Ah so have those proposed changes already been accepted for newer versions of ModemManager?
Oh apologies, I thought you said it had been added already. Looking at the PR/issue discussion it seems nothing has been merged yet.
