Hi,

I'm doing something similar.

My cmake arguments for Azure-IoT-SDK-C are:
-Duse_amqp:BOOL=ON -Duse_http:BOOL=ON -Duse_mqtt:BOOL=ON -Dskip_samples:BOOL=OFF -Duse_prov_client:BOOL=ON -Duse_prov_client_core:BOOL=ON -Dhsm_type_sastoken:BOOL=ON

And for the device update agent I added the following libraries:

+find_package (azure_macro_utils_c REQUIRED)

target_link_libraries (

+prov_device_client

+prov_device_ll_client

+prov_auth_client

+prov_amqp_transport

+umqtt

+prov_mqtt_ws_transport

+hsm_security_client

+utpm

Here is my main diff

With these changes I am able to use ADU agent with DPS.
Note that the connection string format should be

Hi asbarnes,
Thanks for reply
I will try above one.
but i have one problem , i getting below error after running agent code

/usr/bin/AducIotAgent: error while loading shared libraries: libcpprest.so.2.10: cannot open shared object file: No such file or directory

I have build whole code of update sdk on pi 4 ,
Do you have any idea ?

from iot-hub-device-update.

asbarnes avatar asbarnes commented on June 22, 2024

Hi,

Please check scripts/install-deps.sh. It should install cpprest.
If you are using Yocto meta-azure-device-update it is installed as part of deliveryoptimization-sdk.bb

from iot-hub-device-update.

Hi i have solved linking issue by using cmd

sudo ldkconfig

Here is update about implementation and problem.
i have successfully change the code of device update with device provisioning using 0x509.
Device getting register and dps got successfully by merging and linking code from dps sample directory.
but not getting mqtt error in device code.

Hey,
I was my mistake that i entered all credential in code. Now updated and seem like code get connected to iot hub.
But now facing new problem as code getting stuck after subscription in agent and nothing happening after that.

The log says Failed to pass connection string to DO - is your connection string formatted correctly?
Is UseProvisioning=true part of your connection string?

Hi asbarnes,
I am not using any connection string based.
I have found the same the error also coming in out of box pi image from azure

As per my understanding connection string is mandatory.
You can read about my approach for this issue here - #87 (comment)

GauravChoube avatar GauravChoube commented on June 22, 2024

Yes , saw the post and but if suppose that was case how could i connect with iot hub in my implementation.
I simply add dps sample code part to get provision where i get the huburl and device id and
i used the IoTHubDeviceClient_LL_CreateFromDeviceAuth , then its done.

asbarnes avatar asbarnes commented on June 22, 2024

I explained it in other issue. My approach is to perform the provisioning in a different program (let's say, one of azure-iot-sdk-c examples) and then call adu-agent with minimal changes:

Okay you are saying its not possible without connection string.
Can you please confirm about can we do device provisioning for agent code with the help of 0x509 certificate.
As provisioning example explain in prov_client_ll_sample.

@asbarnes
Hi I have successfully implemented the dps provisioning with agent code by same i have explained without using connection string. Some dps code was present for symmetric keys. Used some part of code and mixed with x509 sample code.
finally integrated with agent code.
Thank you much for support
