[Vk5-wx-sonde] auto_rx release v1.0.3

Fri Apr 19 16:13:27 PDT 2019

Looking at that log, it looks like you're getting two lots of telemetry
data coming into chasemapper, arriving just after each other. (i.e.
13:59:33,236, then 13:59:33:466). The behaviour you are seeing is 100%
expected - it's saying that there is no difference in time between the
incoming data samples, and therefore it cannot calculate an ascent rate
(altitude_delta / time_delta).

Do you have two copies of auto_rx running on the network where chasemapper
is running? If so you should disable the horus_udp output on one of them.

Cheers,
Mark
