RE: [Paparazzi-devel] modem question

[Roman Krashanitsa]

Hi  Chen,

In current implementation MaxStream's  Xbee-type modems and Aerocomm modems
can work in two modes: 1/ serial extension mode when modem acts as a serial
cable replacement; and 2/ as an active tranceiver where it uses its own
protocol to efficiently transmit autopilot telemetry wrapped in its own
protocol. Using serial cable replacement mode you will not be able to
transmit any data on to the airplane, only receive telemetry from it.

So, to answer your question, any modem (I think) will work as a serial cable
replacement. But if you want efficiency and fault proof, and to be able to
change parameters in flight you have to implement its own protocol with
adressed packets.

Sincerely,
Roman Krashanitsa
