Thank you for the fast response Vipin! I will check it out, hopefully it works haha

Hi Eric,

Yes I think I resolved all the issues that I faced with respect to TLS socket connection. Please take a look at the my another discussion thread. https://devzone.nordicsemi.com/f/nordic-q-a/98977/psa_generate_key-failed-with-error--134

The above mentioned issue will get resolved if you update the software environment to

ZEPHYR_SDK_VERSION : 0.15.2

NCS: v2.2.99-dev3

But you might face another issue if you wanted to use. both PSA and WPA_SUPPLICANT in your application. I have described my problem in the above given ticket.

Thanks

Hi Vipin, I am getting a 22 err code when I connect using TLS socket, I'm wondering if you have made any progress on this issue since posting? I am using a nrf7002DK and followed the nrf https sample to write my code. Thanks!

Hi,

Honestly speaking, I had tried both the implementation. The good thing is that both gives the same error.

One interesting thing that I noticed now is when I try to open a socket as below throws error for setsockopt()

*sock = socket(res->ai_family, res->ai_socktype, res->ai_protocol);

[00:00:33.839,416] <dbg> net_sock: zsock_socket_internal: (main): socket: ctx=0x20010ae4, fd=0
[00:00:33.839,447] <err> http_client: Failed to setup peer verification, err -109

[00:00:33.839,477] <err> http_client: Establishing socket connection failed
[00:00:33.839,477] <err> http_client: Setup socket connection failed
[00:00:33.839,508] <dbg> net_sock: z_impl_zsock_close: (main): close: ctx=0x20010ae4, fd=0

But when I use *sock = socket(res->ai_family, res->ai_socktype,IPPROTO_TLS_1_2), then I can see socket is opening but network connection fails with -22. Right now I am trying to connect to google.com.

Could you please check that socket(res->ai_family(AF_INET6), res->ai_socktype(SOCK_STREAM), res->ai_socktype(IPPROTO_TLS_1_2)) works fine or should I have to handle differently.

I will try again for sniffer as you mentioned. I am using nRF52840 dongle.

Hi,

I can't see any obvious problem in your code. Can you have a look at the code in the https_client sample in the sdk-nrf repo, to see if this works for you? This is written for nRF9160, but it uses sockets like the example you already based on, so it should be similar modifications needed to make it work with OpenThread.

Also, if you can retry setup of the Sniffer, that will probably help figure out what is failing. I recommend using the nRF52840 Dongle with the sniffer (or nRF52840 DK connected through the NRF_USB port). Make sure you program the sniffer firmware before opening Wireshark, and run the Python command as described in step 3 in the installation guide to make sure no errors are reported from Python, and that the interface is detected correctly.

Best regards,
Jørgen

Hi,

The TLS handshake issue with error code -7780 got fixed after changing the PEM(cert) with PEM(chain) certificate and also enabled some MBEDTLS security config options.

CONFIG_MBEDTLS_KEY_EXCHANGE_RSA_ENABLED=y
CONFIG_MBEDTLS_KEY_EXCHANGE_ECDHE_RSA_ENABLED=y
CONFIG_MBEDTLS_KEY_EXCHANGE_ECDHE_ECDSA_ENABLED=y
CONFIG_MBEDTLS_KEY_EXCHANGE_ECDH_ECDSA_ENABLED=y
CONFIG_MBEDTLS_KEY_EXCHANGE_ECDH_RSA_ENABLED=y
CONFIG_MBEDTLS_MAC_SHA256_ENABLED=y
CONFIG_MBEDTLS_HASH_SHA256_ENABLED=y
CONFIG_MBEDTLS_CIPHER_AES_ENABLED=y
CONFIG_MBEDTLS_CIPHER_GCM_ENABLED=y
CONFIG_MBEDTLS_CIPHER_MODE_CBC=y
CONFIG_MBEDTLS_CIPHER_MODE_CBC_ENABLED=y

But again I am back to my previous error state. By the way did you find any problem with my code snippet I shared? If you can comment on that I could find some clue on the issue.

Hi Jørgen,

Thanks!!!

Before I post my query, I have seen the above mentioned discussion and tried some of the configuration changes but nothing helps.

But I tried to connect to "google.com" using the same code, here I don't see any TLS handshake issue but socket connect is failed here as well.

What do you think about this two different behaviour. Feel free to ask any missing points. I am really blocked because of this issue.

Hi Jørgen,

I could solve the EINVAL(-22) error wrt to TLS socket connection.

But now I am seeing new error. Could you please comment on the below error.

[00:00:33.341,827] <err> net_sock_tls: TLS handshake error: -7780
[00:00:33.343,750] <err> http_client: Cannot connect to IPv6 remote (-113)
[00:00:33.343,780] <err> http_client: Setup socket Failed
[00:00:33.343,780] <err> http_client: Failed to connect to socket

Hi Jørgen,

I didn't make any relevant modification to http_client to harm the working of that (I believe).

static int establish_connection(sa_family_t family, const char* ipv6_addr, int port, int* sock, struct sockaddr* addr, socklen_t addr_len) {
  const char* family_str = family == AF_INET ? "IPv4" : "IPv6";
  int         ret        = 0;

  memset(addr, 0, addr_len);

  if (family == AF_INET) {
    net_sin(addr)->sin_family = AF_INET;
    net_sin(addr)->sin_port   = htons(port);
    inet_pton(family, ipv6_addr, &net_sin(addr)->sin_addr);
  }
  else {
    net_sin6(addr)->sin6_family = AF_INET6;
    net_sin6(addr)->sin6_port   = htons(port);
    inet_pton(AF_INET6, ipv6_addr, &net_sin6(addr)->sin6_addr);
    LOG_DBG("Server address: %s ", ipv6_addr);
  }

#if defined(CONFIG_NET_SOCKETS_SOCKOPT_TLS)
  sec_tag_t sec_tag_list[] = {CA_CERTIFICATE_TAG};

  *sock = socket(family, SOCK_STREAM, IPPROTO_TLS_1_2);
  if (*sock >= 0) {
    ret = setsockopt(*sock, SOL_TLS, TLS_SEC_TAG_LIST, sec_tag_list, sizeof(sec_tag_list));
    if (ret < 0) {
      LOG_ERR("Failed to set %s secure option (%d)", family_str, -errno);
      ret = -errno;
    }

    ret = setsockopt(*sock, SOL_TLS, TLS_HOSTNAME, TLS_PEER_HOSTNAME, sizeof(TLS_PEER_HOSTNAME));
    if (ret < 0) {
      LOG_ERR("Failed to set %s TLS_HOSTNAME "
              "option (%d)",
              family_str, -errno);
      ret = -errno;
    }
  }
#else
  *sock = socket(family, SOCK_STREAM, IPPROTO_TCP);
#endif

  if (*sock < 0) {
    LOG_ERR("Failed to create %s HTTP socket (%d)", family_str, -errno);
  }

  ret = connect(*sock, addr, addr_len);
  if (ret < 0) {
    LOG_ERR("Cannot connect to %s remote (%d)", family == AF_INET ? "IPv4" : "IPv6", -errno);
    ret = -errno;
  }

  return ret;

  }
  else if (final_data == HTTP_DATA_FINAL) {

  if (ret < 0 || *sock < 0) {
    LOG_ERR("Setup socket connection failed");
    return -1;
  }
  return ret;
}

I don't see any critical warnings.

/ncs/zephyr/include/zephyr/zephyr.h:13:2: warning: #warning "<zephyr/zephyr.h> is deprecated, include <zephyr/kernel.h> instead" [-Wcpp]
   13 | #warning "<zephyr/zephyr.h> is deprecated, include <zephyr/kernel.h> instead"

I have tried to setup sniffer but due to some reasons my nrf-sniffer interface is not detected in the Wireshark tool. I tried multiple steps and different version but couldn't succeed.

But by just disabling CONFIG_NET_SOCKETS_SOCKOPT_TLS, the same code works for TCP socket connection and able to send and receive RPC message to our remote server.

Hi,

Can you post the changes you have made to the sample? As far as I can see, the original sample does not implement OpenThread support.

Do you get any warnings when building the application?

Have you done a sniffer trace, to see if there is any error from the on-air traffic?

Best regards,
Jørgen
