Hi, Has anyone success to connected Hive MQ Cloud via Ameba standard SDK MQTT lib ? [http://console.hivemq.cloud/](http://console.hivemq.cloud/) [https://www.hivemq.com/docs/hivemq-cloud/introduction.html](https://www.hivemq.com/docs/hivemq-cloud/introduction.html) My device always received CONNACK with return code is 5 (The Client is not authorized to connect) on MQTT package level. SSL hand shake was success. Regards, ---

Hi @ruanjanc are you using the MQTT example found in `example_mqtt.c`, activated by the macro `#define CONFIG_EXAMPLE_MQTT` ? ---

@wyy Yes, correct I use `example_mqtt.c` , activated by the macro `#define CONFIG_EXAMPLE_MQTT` What I change from default SDK are. 1. Change Heap Size `FreeRTOS.h` `#define configTOTAL_HEAP_SIZE ( ( size_t ) ( 110 * 1024 ) ) // use HEAP5` 2. Switch to use mbed SSL and enable MQTT example `platform_opts.h` `#define CONFIG_USE_POLARSSL 0` `#define CONFIG_USE_MBEDTLS 1` `#define CONFIG_EXAMPLE_MQTT 1` 3. Change (mbed) SSL Max content length `config_rsa.h` `#define MBEDTLS_SSL_MAX_CONTENT_LEN 16384` 4. To run prvMQTTEchoTask `MQTTClient`.h `//#define MQTT_TASK` 5. `example_mqtt.c``prvMQTTEchoTask` Change address `char* address = "xxxxxxxxxxxxxxxxxxxxxxxxx.s1.eu.hivemq.cloud";` Add user name & password `char * user_name = "Usernamexxxxx";` `char * password = "Passwordxxxx";` Config network to use SSL & add Root CA of HiveMQ Cloud `network.rootCA = (char*)rootCABuff;` `network.clientCA = NULL;` `network.private_key = NULL;` `network.use_ssl = 1;` 1. Change port to `8883` follow as HiveMQ Cloud spec. 2. Set connection data `connectData.username.cstring = user_name;` `connectData.password.cstring = password;` `connectData.MQTTVersion = 3;` `connectData.clientID.cstring = "FT1_018";` `connectData.cleansession = 1;` And below is log, as you can see SSL handshake is success. But return code from MQTT is 5 > [Fri Feb 18 21:52:32.717 2022] [5087]mqtt:Connect Network xxxxxxxxxxxxxxxxxx.s1.eu.hivemq.cloud" > [Fri Feb 18 21:52:32.955 2022] > [Fri Feb 18 21:52:32.971 2022] [5331]mqtt:addr = 54.73.92.158 > [Fri Feb 18 21:52:33.196 2022] > [Fri Feb 18 21:52:33.196 2022] [5565]mqtt:root\_crt parse done > [Fri Feb 18 21:52:33.499 2022] > [Fri Feb 18 21:52:33.499 2022] [5868]mqtt: > [Fri Feb 18 21:52:33.499 2022] Verify requested for (Depth 1): > [Fri Feb 18 21:52:33.515 2022] > [Fri Feb 18 21:52:33.515 2022] > [Fri Feb 18 21:52:33.516 2022] [5882]mqtt:cert. version : 3 > [Fri Feb 18 21:52:33.554 2022] serial number : 91:2B:08:4A:CF:0C:18:A7:53:F6:D6:2E:25:A7:5F:5A > [Fri Feb 18 21:52:33.567 2022] issuer name : C=US, O=Internet Security Research Group, CN=ISRG Root X1 > [Fri Feb 18 21:52:33.577 2022] subject name : C=US, O=Let’s Encrypt, CN=R3 > [Fri Feb 18 21:52:33.588 2022] issued on : 2020-09-04 00:00:00 > [Fri Feb 18 21:52:33.599 2022] expires on : 2025-09-15 16:00:00 > [Fri Feb 18 21:52:33.600 2022] signed using : RSA with SHA-256 > [Fri Feb 18 21:52:33.609 2022] RSA key size : 2048 bits > [Fri Feb 18 21:52:33.609 2022] basic constraints : CA=true, max\_pathlen=0 > [Fri Feb 18 21:52:33.624 2022] key usage : Digital Signature, Key Cert Sign, CRL Sign > [Fri Feb 18 21:52:33.641 2022] ext key usage : TLS Web Client Authentication, TLS Web Server Authentication > [Fri Feb 18 21:52:33.672 2022] > [Fri Feb 18 21:52:33.672 2022] > [Fri Feb 18 21:52:33.672 2022] [6033]mqtt: This certificate has no flags > [Fri Feb 18 21:52:33.673 2022] > [Fri Feb 18 21:52:33.673 2022] > [Fri Feb 18 21:52:33.673 2022] [6046]mqtt: > [Fri Feb 18 21:52:33.688 2022] Verify requested for (Depth 0): > [Fri Feb 18 21:52:33.688 2022] > [Fri Feb 18 21:52:33.688 2022] > [Fri Feb 18 21:52:33.688 2022] [6061]mqtt:cert. version : 3 > [Fri Feb 18 21:52:33.704 2022] serial number : 04:33:4E:59:4E:0A:6B:F4:EE:70:04:55:E0:8D:E0:89:BB:A9 > [Fri Feb 18 21:52:33.747 2022] issuer name : C=US, O=Let’s Encrypt, CN=R3 > [Fri Feb 18 21:52:33.760 2022] subject name : CN=\*.s1.eu.hivemq.cloud > [Fri Feb 18 21:52:33.772 2022] issued on : 2022-01-09 15:25:32 > [Fri Feb 18 21:52:33.773 2022] expires on : 2022-04-09 15:25:31 > [Fri Feb 18 21:52:33.784 2022] signed using : RSA with SHA-256 > [Fri Feb 18 21:52:33.792 2022] RSA key size : 2048 bits > [Fri Feb 18 21:52:33.792 2022] basic constraints : CA=false > [Fri Feb 18 21:52:33.800 2022] subject alt name : \*.s1.eu.hivemq.cloud, s1.eu.hivemq.cloud > [Fri Feb 18 21:52:33.815 2022] key usage : Digital Signature, Key Encipherment > [Fri Feb 18 21:52:33.831 2022] ext key usage : TLS Web Server Authentication, TLS Web Client Authentication > [Fri Feb 18 21:52:33.849 2022] > [Fri Feb 18 21:52:33.849 2022] > [Fri Feb 18 21:52:33.849 2022] [6215]mqtt: This certificate has no flags > [Fri Feb 18 21:52:33.862 2022] > [Fri Feb 18 21:52:34.309 2022] > [Fri Feb 18 21:52:34.309 2022] [6672]mqtt:ssl handshake success > [Fri Feb 18 21:52:34.309 2022] > [Fri Feb 18 21:52:34.324 2022] [6684]mqtt:“xxxxxxxxxxxxxxxxxxxxx.s1.eu.hivemq.cloud” Connected > [Fri Feb 18 21:52:34.340 2022] > [Fri Feb 18 21:52:34.340 2022] [6705]mqtt:Start MQTT connection > [Fri Feb 18 21:52:34.547 2022] > [Fri Feb 18 21:52:34.547 2022] [6911]mqtt:Read packet type: 2 > [Fri Feb 18 21:52:34.548 2022] > [Fri Feb 18 21:52:34.548 2022] [6920]mqtt:Return code from MQTT connect is 5 Regards,
