Re: [Paparazzi-devel] no link :(

Make sure you are specifying the correct UART.  Tiny1 and Tiny2 are different.  
Also, be sure that your modem UARTs are set to the same baud as the rest of 
your hardware (9600 is the default for xbee, I think).  Lastly, I have no idea 
what the "datalink" section of the airframe file does, only that it's needed 
for maxtream api mode.  I always comment out the entire section when operating 
in transparent mode.

Hello, I am having issues with the link, no messages are coming in,
and gcs not populing. I am using a xbee-xsc development board on
ttyusb0 (which is recieving something since I can get hex output if i
open the device in another application)
thank you, please help

Here is what is in airframe file:

<section name="DATALINK" prefix="DATALINK_">
    <define name="DEVICE_TYPE" value="PPRZ"/>
    <define name="DEVICE_ADDRESS" value="...."/>
  </section>

flags:

ap.CFLAGS += -DDOWNLINK -DUSE_UART1 -DDOWNLINK_TRANSPORT=PprzTransport
-DDOWNLINK_FBW_DEVICE=Uart1 -DDOWNLINK_AP_DEVICE=Uart1
-DPPRZ_UART=Uart1 -DDATALINK=PPRZ -DUART1_BAUD=B9600
ap.srcs += downlink.c $(SRC_ARCH)/uart_hw.c datalink.c pprz_transport.c

and here is the the session I am trying to execute:

<session name="Flight address@hidden">
<program name="Data Link">
      <arg flag="-d" constant="/dev/ttyUSB0"/>
      <arg flag="-transport" constant="pprz"/>
      <arg flag="-uplink" constant=""/>
      <arg flag="-s" constant="9600"/>
      </program>
      <program name="Server"/>
      <program name="GCS"/>
      <program name="Messages">
        <arg flag="-c" constant="telemetry"/>
     </program>
