Serial output is not working properly
I don't know exactly. I looked up how to find out, and it said to run
which just shows the startup banner. The banner says Ω-ware: 0.3.3 b251 but I'm not sure what part of that, if any, is the version

Can you test the 232 port with OpenWrt 22.03 latest release?
For the version information: cat /etc/openwrt_release
For Onion firmware version: onion os version
The OpneWRT version is 18.06-snapshot
The Onion firmware version is v0.3.3 b251
And the onion os version is 1.0.6-1
I have tested the serial output with the echo command with the most recent version of OpenWRT, and it has the same problem, so the problem doesn't seem to be a problem with the LTE OS

In that case, it is the Hardware issue.
You can go back to LTE os image.
I saw no RS232 port on LTE board.
How did you add the 232 transceiver?
Do you have sketch or schematics to show here?
Well that would be the problem, I was using the serial port. However, the device I was originally trying to use doesn't need RS232 (it can be connected directly to an arduino uno). I'll convert the signal to RS232 for the purposes of debugging, and hopefully that will illustrate how to solve the problem. Will installing the OpenWRT 18.06 let me get the LTE OS back, or do I have to find it specifically some other way?
I am using the UART1 of Omega2 -
/dev/ttyS1for GPS module communication with 115200bps.
It is 24/7 running for more than 3 weeks constantly.
Working with no error.
So I cannot guess what will be your issue on LTE board.
