Hi All -

has anyone managed to connect the 2nd Gen starter kit to AWS?

Is it possible to cross compile following embedded C SDK?

https://github.com/aws/aws-iot-device-sdk-embedded-C

Thanks for any pointers.

Hi,

We're still in the development stage (haven't deployed anything in the field yet) with the SK2 but have had no problems connecting it to AWS using that SDK.  We developed our application on a Linux desktop and porting it to the SK2 was simple (pretty much just recompiled it).  The SDK you reference has some sample applications (and a few external source trees you need to pull down). Once you have the external source trees set up cross compiling is no problem. Just sourced the SK2 build environment and build (overriding a hard-coded compiler in the Makefile):

$ . /usr/local/oecore-x86_64/environment-setup-cortexa7-neon-vfpv4-oe-linux-gnueabi

$ cd aws-iot-sdk/samples/linux/shadow_sample

$ make CC="$CC"

. . .

$ file shadow_sample
shadow_sample: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=eb69fbf5d0e011c40b0ad89653664063ecbe0839, not stripped

Awesome, David.  Works just fine.  It was the hard coded compiler in make file that did the trick!  Thank you

Hi David - I've been struggling with an connection error.  I know many people have solved it but I've been tail-chasing.  Any advice would be apprectiated:  (have checked all certs multiple times)

RROR: iot_tls_connect L#238  failed
  ! mbedtls_ssl_handshake returned -0x2700

ERROR: iot_tls_connect L#245     Unable to verify the server's certificate. Either it is invalid,
    or you didn't set ca_file or ca_path to an appropriate value.
    Alternatively, you may want to use auth_mode=optional for testing purposes.

ERROR: main L#191 Error(-4) connecting to a178bfmk0ytfxt-ats.iot.us-west-2.amazonaws.com:443

Apologies if I should start new topic. 

 

Actually, I'm struggling with that too.  I have some old certificates (provisioned in July) that work just fine, it is the recently provisioned ones that don't work.  In fact, the new certs work find with the nodejs SDK.  There is something about the new certificates and the C SDK that needs fixing.  I get the same bad behavior on my laptop, it isn't a problem with the SK2. I'm planning on asking in the AWS IOT forum just haven't gotten around to it yet.

I have mine working with all the proper ATS certs.  I'm not sure how I managed to do it after over 20 hours but it's working (for now).  Let me know if I can verify any settings or post any files for you David.

Sweet.  Can you post or send me your aws_iot_config.h?  Specifically I am wondering which of the root certs you were successful with (IIRC there are 4).  Also, did you make any changes to the source to get it to work?  For example, any changes to external_libs/mbedTLS/include/mbedtls/config.h.

i hope it's still working.  i stopped it 3 hours ago.  I made a *lots* of changes but according to my notes all should have been backed out (but it was late night so may have slipped up on note taking).

here is the relevant files:

Thanks for the info.  It was helpful to know that you had connected.  It looks like it is working for me now.  I think my root problem was not having unique thing ids.
