If the kit in question has an LG-01, then that issue falls under my statement that “Trying to use a node class radio in a gateway role is rarely worthwhile.”
But what the original post I was replying said was that “its firmware was not compatible”
The issue with an LG01 or LG02 is not that the firmware cannot be made compatible with a given bandplan, it is that the hardware is not really suitable for the gateway role in LoRaWAN.
If the asker had something like an LG308 with an actual gateway-class radio in it then any current software incompatibilities would be a stumbling block that could be overcome with better software.
And by extension, in a situation where LBT is required, if a gateway lacks support for that, the issue is not really that it is missing from the software, but that it is missing hardware capable of reading non-LoRa signal strength. Where that hardware is present, replacing software that doesn’t utilize it with software that does should be possible.
