Other Parts Discussed in Thread: SHA-256, CC3220SF, UNIFLASH
Tool/software: TI-RTOS
Hello,
Recently i program the CC3220SF-LAUNCHXL with Subscribe_publish_sample program to connect to the AWS IOT Core. But i cannot able to connect the AWS IOT Server , the IOT AWS Server is not Sending ACK response.(iot_tls_read function (recv() returned 0))
Versions Info
Simplink Version : simplelink_cc32xx_sdk_2_30_00_05
AWS IOT Plugin : aws_cc32xx_2_10_00_04
Service pack : sp_3.9.0.6_2.0.0.0_2.2.0.6.bin
Application fails in the aws_iot_mqtt_internal_wait_for_read() function and returns Error NETWORK_SSL_READ_ERROR.
File Name : aws_iot_mqtt_client_connect.c+424
/* send the connect packet */
rc = aws_iot_mqtt_internal_send_packet(pClient, len, &connect_timer);
if(SUCCESS != rc) {
FUNC_EXIT_RC(rc);
}
/* this will be a blocking call, wait for the CONNACK */
rc = aws_iot_mqtt_internal_wait_for_read(pClient, CONNACK, &connect_timer);
if(SUCCESS != rc) {
FUNC_EXIT_RC(rc);
}
NOTE : The Yellow highlighted function fails because the sub function recv() in iot_tls_read() return 0.
My Various Configuration are as Follows.
1. aws iot configuration
#define AWS_IOT_MQTT_HOST "xxxxxxxxxxxxxx-ats.iot.ap-south-1.amazonaws.com"
#define AWS_IOT_MQTT_PORT 8883
#define AWS_IOT_MQTT_CLIENT_ID "arn:aws:iot:ap-south-1:xxxxxxxxxxxx:thing/aws_iot"
#define AWS_IOT_MY_THING_NAME "aws_iot"
2. AWS policy in aws iot core server
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "iot:*",
"Resource": "*"
}
]
}
My Certificate files are formatted like this
I am Using ats endpoint in Mumbai Region. The Root CA Certificate is used is RSA 2048 Bit Key.
unsigned char root_ca_pem[] =
"-----BEGIN CERTIFICATE-----\r\n"
"MIIDQTCCAimgAwIBAgITBmyfz5m/jAo54vB4ikPmljZbyjANBgkqhkiG9w0BAQsF\r\n"
<>
"rqXRfboQnoZsG4q5WTP468SQvvG5\r\n"
"-----END CERTIFICATE-----";
As pe rthe following thread https://e2e.ti.com/support/wireless-connectivity/wifi/f/968/t/735565#mce_temp_url#
I used both the endpoint for connection.But Still it is failing.
With ATS : xxxxxxxxxxxxxx-ats.iot.ap-south-1.amazonaws.com
Without ATS : xxxxxxxxxxxxxx.iot.ap-south-1.amazonaws.com
I also have the correct time stamp. Offsetted(added 19800) with the GMT to get the Local time.
do {
/* Get the time using the built in NTP server list: */
retval = SNTP_getTime(NULL, 0, &timeval, &ntpTimeStamp);
if (retval != 0) {
Display_printf(display, 0, 0,
"startSNTP: couldn't get time (%d), will retry in %d secs ...",
retval, NTP_POLL_TIME);
sleep(NTP_POLL_TIME);
Display_printf(display, 0, 0, "startSNTP: retrying ...");
}
/* Save the current (NTP Epoch based) time */
currentTimeNtp = (ntpTimeStamp >> 32) + 19800; /* Offsetted the 5:30 hrs with respect to GMT*/
} while (retval < 0);
/*
Any help would be very Helpful
