Hi all,
maybe only few OMs in my area will be able to test this, but
it's worth sharing the experiment with a wider audience.
I'm using LoRa since a while for APRS and for "Packet Radio".
What I'm going to write below is about the second.
I've loaded the RNode firmware on my LoRa device and I've configured it
as a KISS TNC. Second step was to connect via serial (with USB
cable) the KISS TNC. The port definition in BPQ32.cfg is just a regular
KISS port.
For my in-house testing I have a similar setup with a laptop.
The transfer rate is pretty decent and the netrom link is stable.
I now have a short external antenna on top of the roof. Next test will
be to go a bit far by car with my portable station. I'll let you know!
