| Re: [paho-dev] Question AWS IoT TLS V1.2 |
Hello John, i found the error in my paho script i try with “client.tls_set(awsCert, deviceCertificate, devicePrivateKey, ssl.CERT_REQUIRED, ssl.PROTOCOL_TLSv1_2)” only Python >2.7.8 but your implementation is “client.tls_set(awsCert, deviceCertificate, devicePrivateKey, ssl.CERT_REQUIRED, ssl.PROTOCOL_SSLv23)” for Python 2.7.3 I do not understand very well the security implementation. SSLv2 or SSLv3 is not the same as TLSv1.2 TLSv1.2 is not yet condition for AWS Iot? And a other question and remark. Some time ago i tested the Arduino C++ Paho Implementation. Its running good but after seven days or two, (was very different) the Arduino stopped to send MQTT Messages. Then I had a discussion with Ian Craggs. Ian saw its a memory overflow. Many strings the change for the MQTT Messages in a small Embedded Device and Memory is not the solution for a long time. Whats the reason thats amazon build of the complete Paho C++ Implementation than communitcation to serial? There are already test for a long time with this implementation? Best Regards Reiko Von: paho-dev-bounces@xxxxxxxxxxx [mailto:paho-dev-bounces@xxxxxxxxxxx] Im Auftrag von Rotach, John Hello Reiko, Glad to hear you're trying out AWS IoT with the Yún. I encourage you to check out the AWS supported Yún SDK here: It is the goal of this SDK to allow developers to target AWS IoT using the Arduino IDE and do minimal setup on the AR9331 processor / OpenWRT OS. To accomplish this the SDK creates a python process on the linux processor which uses the Paho python MQTT client and communicates with the user's Arduino sketch using the serial bridge. Documentation in the repo above gives a good description of this architecture. One of the packages installed by the setup script is python-openssl which enables the TLS connection to the service. This SDK also includes the source for the python runtime so you could take a look at that if you'd like to connect using your own python program on the AR9331. Best regards, John SDE, AWS IoT From: <paho-dev-bounces@xxxxxxxxxxx> on behalf of Reiko Nötzold <reiko.noetzold@xxxxxxxxx> a questions to amazon AWS IoT Paho Implementation. AWS IoT needs TLS V1.2. But what is the difference to Arduino YUN Implementation in C++ and the other way in Python? At YUN runs only Python 2.7.3 without TLS V1.2 support. :-( With Python 3.5 and "import paho.mqtt.client as mqtt" i can connect and subscribed AWS IoT. Whats the trick and other side of “AWS IoT Arduino YUN Paho C++ Implementation” that could connect with TLS V1.2? Reiko |
