Hi, I also have this problem. Did you solve it?

[farmsensor]

I have it running now, by making these changes: change ci.ssl_min_version = MQTT_SSL_VERSION_SSLv3; to ci.ssl_min_version = MQTT_SSL_VERSION_TLSv1_2;

delete: ci.entropy_custom = "GPRS_A9"; ci.will_qos = 2; ci.will_topic = "will"; ci.will_retain = 1; memcpy(strstr(willMsg,"GPRS")+5,imei,15); ci.will_msg = willMsg;

@farmsensor Hello! I have this problem too! Deleted as you indicated. Here is some of the code MQTT_Client_t* client = MQTT_ClientNew(); MQTT_Connect_Info_t ci; MQTT_Error_t err; memset(&ci,0,sizeof(MQTT_Connect_Info_t)); ci.client_id = imei; ci.client_user = CLIENT_USER; ci.client_pass = CLIENT_PASS; ci.keep_alive = 60; ci.clean_session = 1; ci.use_ssl = true; ci.ssl_verify_mode = MQTT_SSL_VERIFY_MODE_REQUIRED; ci.ca_cert = ca_crt; ci.ca_crl = NULL; ci.client_cert = client_crt; ci.client_key = client_key; ci.client_key_passwd = NULL; ci.broker_hostname = BROKER_HOSTNAME; ci.ssl_min_version = MQTT_SSL_VERSION_TLSv1_2; ci.ssl_max_version = MQTT_SSL_VERSION_TLSv1_2;

It connects to the server and immediately disconnects. Help, how you defeated the problem in more detail. BROKER_IP "a19eh4w67cred3-ats.iot.us-west-2.amazonaws.com" BROKER_PORT 8883 BROKER_HOSTNAME "us-west-2.amazonaws.com" CLIENT_USER NULL CLIENT_PASS NULL SUBSCRIBE_TOPIC "$aws/things/ThingOne/shadow/update/accepted" PUBLISH_TOPIC "$aws/things/ThingOne/shadow/update" PUBLISH_INTERVAL 5000 PUBLISH_PAYLOEAD "{ \"state\": { \"reported\": { \"state\": 0 } }}"

this is still not working

I am getting these two errors : Missing encoded blocks 0/1 NbTx 2 TxBitMap 0x0\n pending TBF,invalid data

Has anyone successfully been able to connect A9/A9G to AWS IoT core?
