The Maxstream API protocol (xbee) is most useful for simultaneous
control of multiple aircraft and requires the xbee_init string to be
configured and sent to the modem at least once to program
the ID number
among other things. If you have no need for the API
protocol, the best
method is to just use transparent serial (pprz) with the modems in
their default configuration. They should work right out of
the box in
place of your Aerocomm modems without any configuration
changes at all.
I do recommend that you set them to a higher baud rate (56K)
and that
can be done with the Maxstream software.

hi,
I am trying to use the xbee and i am having some problemes
with the up
link.
The down link works normally but i am not able to change block in
flight plan or anything else that require an up link. It
doesn't work
better with my FTDI cable, what makes me think the bug is in my GCS
session. The GCS doesn't seem to send anything, the tx led
on the modem
isn't blinking. Here is the session i am using:
<session name="7 Xbee">
<program name="link">
<arg flag="-d" constant="/dev/ttyUSB0"/>
<arg flag="-uplink" constant=""/>
<arg flag="-transport" constant="xbee"/>
<arg flag="-s" constant="9600"/>
</program>
<program name="server"/>
<program name="messages">
<arg flag="-c" constant="telemetry:*"/>
</program>
<program name="gcs">
<arg flag="-mercator" constant=""/>
<arg flag="-ref" constant="WGS84 53.301387 -60.429488"/>
<arg flag="-center" constant="WGS84 53.301387 -60.429488"/>
<arg flag="zoom" constant="0.08"/>
</program>
</session>
Everything steel work perfect when i use the aerocomm with an
appropriate session. If anybody have a clue what could cause
that, please help me.
thanks
Simon
