+/* tls_server_bearssl - simple BearSSL TLS server that outputs some statistics to a connecting client,
+ * then closes the socket.
+ *
+ * Uses code from the server_basic example in BearSSL and the tls_server example.
+ *
+ * To test this program, connect to the ESP using openssl command line like this:
+ *
+ * openssl s_client -connect 192.168.66.209:800
+ *
+ * The openssl command line client will print some information for the (self-signed) server certificate,
+ * then after a couple of seconds (validation) there will be a few lines of text output sent from the ESP.
+ *
+ * See the certificate.h and key.h files for private key & certificate, plus information for generation.
