Issue with connecting to iothub over MQTT for Android #328

Closed mahalakshmirathinam closed 6 years ago

mahalakshmirathinam commented 6 years ago

Description of the issue:

Trying to cross-compile Azure C sdk version 1.1.28 to android arm32 bit device. I did it successfully but the ported libraries and samples does not connect to azure iot hub.

Getting the following error. Info: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed Info: Closing tlsio from a state other than TLSIO_STATE_EXT_OPEN or TLSIO_STATE_EXT_ERROR

Can you help me to figure out the issue.

Hi @mahalakshmirathinam , could you verify your SSL installation against the Azure IoT Hub please? Follow the instructions in this issue to verify: https://github.com/Azure/azure-iot-sdk-c/issues/198 Also please send back the version of the ssl lib as the other customer did in this issue. Thanks, Azure IoT Team

Used the openssl version 1.0.2l

I even tried with IoTHubClient_LL_SetOption(iotHubClientHandle, OPTION_TRUSTED_CERT, certificates

with first certificate given in certs.c

I'm getting this error

Please help me to resolve this issue.

Did you try checking the openssl authentication against your hub (using the openssl application), like suggested in #198? What is the output?

ewertons commented 6 years ago

Now this is interesting... you are getting responses back from the service (<- CONACK), so the TLS connection was established. When you provided the certificate using "IoTHubClient_LL_SetOption(iotHubClientHandle, OPTION_TRUSTED_CERT" you seem to have passed your initial issue.

Is your connection string correct?

mahalakshmirathinam commented 6 years ago

Yes. My connection string is correct.

Hi @mahalakshmirathinam , this issue is quite old and we didn't have the details above from your openssl test (2 comments above). If you still face issues please reopen the ticket and we will follow up. Thanks, Azure IoT Team.

@mahalakshmirathinam it occurs error when I cross-compile Azure C SDK to android arm32 bit device:

/home/ubuntu/toolchain/bin/../lib/gcc/arm-linux-androideabi/4.9.x/../../../../arm-linux-androideabi/bin/ld: error: cannot find -lpthread

/home/ubuntu/toolchain/bin/../lib/gcc/arm-linux-androideabi/4.9.x/../../../../arm-linux-androideabi/bin/ld: error: cannot find -lrt

toolchain.cmake:

OS version: 4.4.2 (sdk version 19) Cross compile toolchain: arm-linux-androideabi (generated by NDK,version 4.9)

Have you ever encountered the same problem? What's the toolchain you used? Could you please give me some advices about that?

Thanks so much.
