Got our first TRB254 delivered today.
Set it up based on an email I received before purchasing, I installed and got ZeroTier working great.
But when it came to set up the RS232 as an SMS-modem, I could not find the right settings, so I checked for new firmware.
In the changelog, I could see the modem-setting being added, so I upgraded the firmware.
But now, ZeroTier is not on the listed in "Package Manager", and when I try to upload the version I downloaded on the Teltonika-site (Networking_trb2xx_manual_packages_zerotier_2020-04-20_signed.ipk), I get the following error in the lower right-hand corner: "There is not enough available memory to install the package.
The package-file is 381kb, and based on the System-page there is 0.41 / 1.25 MB used (32,89%).
The modem is now using internal firmware version TRB2_R_00.02.06.1 / EC25EUXGAR08A02M1G.
