high level client crash

[sanbeam]

Client crashes with the following issue.

{"devAddr":{"adapter":2,"flags":0,"ifindex":0,"port":0,"addr":""},"addr":{"adapter":2,"flags":0,"ifindex":0,"port":0,"addr":""},"connType":131072,"identity":[],"result":255,"sequenceNumber":0,"resourceUri":"/oic/res","rcvdVendorSpecificHeaderOptions":[]}

Error: findResources: Unexpected response

[sanbeam]

Bump. Someone please look into this.

[gabrielschulhof]

It looks like some server on the network is issuing OC_STACK_ERROR in response to a resource discovery. I would say check the server, and attach an error handler to the client so it doesn't end up throwing a fatal exception.

Discovery worked for me on 1.2 using high level client / server... but then hang, I will have to investigate too

[sanbeam]

Just curious. Is security enabled by default ?

[sanbeam]

Just curious. Is security enabled by default ? If yes, how do i get insecure version at npm install ?

[rzr]

upstream and meta-oic have SECURED=0 by default on 1.2.1 and under, I aligned to that

[gabrielschulhof]

If you want to build with SECURED=0 you have to build iotivity externally, then export OCTBSTACK_CFLAGS and OCTBSTACK_LIBS.

[sanbeam]

Thanks for confirming. I think these two were the issues. I ll test and update soon.

[sanbeam]

Did the following steps.

1. package.json : "iotivity-node": "git+https://github.com/otcshare/iotivity-node#maintenance"

2. git clone https://git.iotivity.org/iotivity
   pushd iotivity
   git fetch --all --tags --prune
   git checkout tags/1.2.0 -b 1.2.0
   git clone https://github.com/01org/tinycbor.git extlibs/tinycbor/tinycbor
   pushd extlibs/tinycbor/tinycbor/
   git checkout tags/v0.3.2
   popd
   echo "Now in " pwd
   scons resource SECURED=0 TARGET_TRANSPORT=IP
   echo "Build Completed"
   export IOTIVITY_DIR=pwd
   export OCTBSTACK_CFLAGS="-I$IOTIVITY_DIR/resource/csdk/stack/include
   -I$IOTIVITY_DIR/resource/csdk/connectivity/inc/
   -I$IOTIVITY_DIR/resource/csdk/connectivity/api
   -I$IOTIVITY_DIR/resource/include
   -I$IOTIVITY_DIR/resource/oc_logger/include/
   -I$IOTIVITY_DIR/resource/c_common/oic_string/include/
   -I$IOTIVITY_DIR/resource/c_common/oic_malloc/include/
   -I$IOTIVITY_DIR/resource/c_common/
   -I$IOTIVITY_DIR/resource/c_common/oic_time/include/
   -I$IOTIVITY_DIR/resource/c_common/
   -I$IOTIVITY_DIR/resource/c_common/ocrandom/include/
   -I$IOTIVITY_DIR/extlibs/tinycbor/tinycbor/src
   -I$IOTIVITY_DIR/resource/csdk/stack/include/"
   export OCTBSTACK_LIBS="-L$IOTIVITY_DIR/out/linux/x86_64/release -loc -loctbstack -lconnectivity_abstraction -loc_logger"
   echo $IOTIVITY_DIR
   echo $OCTBSTACK_CFLAGS
   echo $OCTBSTACK_LIBS
   popd
   echo "Now in pwd "
   npm install

3. Step 2 went fine.

@gabrielschulhof, please help me set this up.

Forgot to add ROUTING_EP. My bad.
