Hi,

I tried to implement the MQTT Demo with Certificates. I had the Private Key File, Certificate File Name, CA File Name.

I uploaded the above three files with ".key", ".crt" and ".der" formats respectively.

Now it constantly giving me error - 688 i.e. "

SL_ERROR_BSD_ESEC_ASN_NO_SIGNER_E

"

I have also changed the MQTTClient_ConnParams as shown below.

char *Mqtt_Client_secure_files[CLIENT_NUM_SECURE_FILES] = {"client.key", "client.crt", "ca.der"};

MQTTClient_ConnParams Mqtt_ClientCtx = {
MQTTCLIENT_NETCONN_IP4 | MQTTCLIENT_NETCONN_SEC |
MQTTCLIENT_NETCONN_SKIP_DOMAIN_NAME_VERIFICATION,
SERVER_IP_ADDRESS,
SECURED_PORT_NUMBER,
SLNETSOCK_SEC_METHOD_TLSV1_2,
SLNETSOCK_SEC_CIPHER_FULL_LIST,
CLIENT_NUM_SECURE_FILES,
Mqtt_Client_secure_files
};

Hello,

Have you tried following our SimpleLink academy? We have steps for setting up a secure MQTT client here.

I want to verify the client.key and client.pem. But the server keeps on returning the same thing "peer did not return a certificate"

Hello,

Error -688 typically indicates that a certificate in the chain could not be verified, likely because the CA programmed in the file system is not the CA that signed the chain. Are you using your own certificates or ours?
