# avoid a timeout race condition where ArduPilot re-requests a

# Since ArduPilot has a 1s timeout on re-requesting, This only

# - and that has been seen in practise on Travis

NotAchievedException: Expected request for seq=1
The "AT" timestamps there are wallclock time. Since speedup for Rover
is 8 by default, that could be as much as 1.6 seconds meaning a
re-request from ArduPilot would be legitimate.
I've added some debug, too - we now emit "Sending item with seq=1"
between those two "Got" lines. That should make the problem clearer -
we've received a re-request rather than a request for the item after the
one we've already sent.
On the assumption that ArduPilot processes mavlink packets
synchronously (or at least in order), after we have run a timesync
roundtrip we can reasonably expect any mavlink command we have sent
prior to the roundtrip to have been processed, and we should be able to
see the results in the mavlink stream.
There's a race condition with MAVProxy; it's fetching parameters here
and seems to ignore our requests.
Also correct named parameter from retry to attempts
