Dynamic Client

[zinkett]

I would like to give the possibility to connect with Ethernet or WiFi or Modem (one of the three, decided during configuration..).
I have an ESP32.

At the moment I initialize all the Client at the same time:

std::unique_ptr<SSLClientParameters> mTLS;
SSLClient clientETH_secure(clientETH, TAs, (size_t)TAs_NUM, 35, 1, SSLClient::SSL_WARN);
SSLClient clientWIFI_secure(clientWIFI, TAs, (size_t)TAs_NUM, 35, 1, SSLClient::SSL_WARN);
SSLClient clientModem_secure(clientModem, TAs, (size_t)TAs_NUM, 35, 1, SSLClient::SSL_WARN);

and then in the setup() I decided only for one of them:

....
if(isModem){
  mTLS = std::unique_ptr<SSLClientParameters>(new SSLClientParameters(SSLClientParameters::fromPEM(my_CERT_CRT, sizeof my_CERT_CRT, my_CERT_PRIVATE, sizeof my_CERT_PRIVATE)));
  clientModem_secure.setMutualAuthParams(*mTLS);
  mqtt.setClient(clientModem_secure);
}

But using this way, I have some memory problem..
Is there an easier and better way?

Thank you!
