[Paparazzi-devel] Xbee API

[Bart Remes]

Hello World,

I`m playing whit the Xbee API. The goal is to have multiple paprazzi systems in the air.

The problem is that I can not send any data to the Tiny 2.11 board.

I get all the Data from the Tiny 2.11 board in the GCS but I can not upload way points or tuning parameters to the Tiny 2.11 board.(I compiled tuning.xml)

This is what I do:

I integrated the Maxstrem API protocol in my Airframe file

<section name= "MISC">

...

    <define name="XBEE_INIT" value="\"ATCHC\rATID3332\rATPL4\rATRN1\rATTT80\rATBD3\rATWR\r\""/>

    <!-- <define name="NO_XBEE_API_INIT" value="TRUE"/>   uncommant after programed-->

...

</section>

and in the make part I integrated:

# Maxstream API protocol

ap.CFLAGS += -DDOWNLINK -DUSE_UART1 -DDOWNLINK_TRANSPORT=XBeeTransport -DDOWNLINK_FBW_DEVICE=Uart1 -DDOWNLINK_AP_DEVICE=Uart1 -DXBEE_UART=Uart1 -DDATALINK=XBEE -DUART1_BAUD=B9600

ap.srcs += downlink.c $(SRC_ARCH)/uart_hw.c datalink.c xbee.c

I flash this in to the autopilot let it on for 30 sec

and flash than:

<section name= "MISC">

...

    <define name="XBEE_INIT" value="\"ATCHC\rATID3332\rATPL4\rATRN1\rATTT80\rATBD3\rATWR\r\""/>

     <define name="NO_XBEE_API_INIT" value="TRUE"/>   <!--uncommant after programed-->

...

</section>

now I have data from the auto pilot but can not sent anything back 

when I remove this line:

<define name="XBEE_INIT" value="\"ATCHC\rATID3332\rATPL4\rATRN1\rATTT80\rATBD3\rATWR\r\""/>

I also can send data to the autopilot.

If anybody have an idea what I`m doing wrong pleas let me know.

Kind regards

 Bart Remes
