I’m trying to use Application Layer Clock Synchronization.
I enabled it in the Console under General Settings, and I’ve implemented communication based on the TS003 specification. I believe I’m sending valid uplink packets, but I’m not receiving any downlinks.

I haven’t been able to find detailed information on what exactly needs to be configured or how this feature is supposed to work in practice.

From what I understand, it should work starting from version 3.25.0 when enabled, using FPort 202, as stated in the specification.
However, I haven’t found any practical examples or usage guidelines anywhere.

For context: I’m using an Adafruit Feather 32u4 LoRa board with the SlimLora library.
Due to the limited flash memory (32kB), I’m looking for a lightweight way to synchronize real-time clock data.
