Way cool...
Looking at your RSSI values they are all inside the """blockbusting""", (strong), area.
I am used to working below -120dBm on BWs less the 3KHz wide, often down -130dBm on SSB for SSTV for receiving, and, transmitting at power levels of +50 to 60dBm, 100W to 1KW...
Great work and you are getting it all working remarkably quickly. Kudos...
When I had my Arduino about 12+ years ago or so there were none of these add-ons so we had to design and build our own which, without serious test gear was beyond the average user. A Spec-An like our HP one cost us around 25,000 UKP in the mid 90s which would be needed to create a """clean""" 2.4 GHz signal at 300mW...
<thumbs up> <terrific> smileys here...

net::server::proto::ssl
Net::Server::Proto::SSL(3) User Contributed Perl Documentation Net::Server::Proto::SSL(3)
NAME
Net::Server::Proto::SSL - Net::Server SSL protocol.
SYNOPSIS
Until this release, it was preferrable to use the Net::Server::Proto::SSLEAY module. Recent versions include code that overcomes original
limitations.
See Net::Server::Proto. See Net::Server::Proto::SSLEAY.
use base qw(Net::Server::HTTP);
main->run(
proto => 'ssl',
SSL_key_file => "/path/to/my/file.key",
SSL_cert_file => "/path/to/my/file.crt",
);
# OR
sub SSL_key_file { "/path/to/my/file.key" }
sub SSL_cert_file { "/path/to/my/file.crt" }
main->run(proto = 'ssl');
# OR
main->run(
port => [443, 8443, "80/tcp"], # bind to two ssl ports and one tcp
proto => "ssl", # use ssl as the default
ipv => "*", # bind both IPv4 and IPv6 interfaces
SSL_key_file => "/path/to/my/file.key",
SSL_cert_file => "/path/to/my/file.crt",
);
# OR
main->run(port => [{
port => "443",
proto => "ssl",
# ipv => 4, # default - only do IPv4
SSL_key_file => "/path/to/my/file.key",
SSL_cert_file => "/path/to/my/file.crt",
}, {
port => "8443",
proto => "ssl",
ipv => "*", # IPv4 and IPv6
SSL_key_file => "/path/to/my/file2.key", # separate key
SSL_cert_file => "/path/to/my/file2.crt", # separate cert
SSL_foo => 1, # Any key prefixed with SSL_ passed as a port hashref
# key/value will automatically be passed to IO::Socket::SSL
}]);
DESCRIPTION
Protocol module for Net::Server based on IO::Socket::SSL. This module implements a secure socket layer over tcp (also known as SSL) via
the IO::Socket::SSL module. If this module does not work in your situation, please also consider using the SSLEAY protocol
(Net::Server::Proto::SSLEAY) which interfaces directly with Net::SSLeay. See Net::Server::Proto.
If you know that your server will only need IPv4 (which is the default for Net::Server), you can load IO::Socket::SSL in inet4 mode which
will prevent it from using Socket6 and IO::Socket::INET6 since they would represent additional and unsued overhead.
use IO::Socket::SSL qw(inet4);
use base qw(Net::Server::Fork);
__PACKAGE__->run(proto => "ssl");
PARAMETERS
In addition to the normal Net::Server parameters, any of the SSL parameters from IO::Socket::SSL may also be specified. See
IO::Socket::SSL for information on setting this up. All arguments prefixed with SSL_ will be passed to the IO::Socket::SSL->configure
method.
BUGS
Until version Net::Server version 2, Net::Server::Proto::SSL used the default IO::Socket::SSL::accept method. This old approach introduces
a DDOS vulnerability into the server, where the socket is accepted, but the parent server then has to block until the client negotiates the
SSL connection. This has now been overcome by overriding the accept method and accepting the SSL negotiation after the parent socket has
had the chance to go back to listening.
LICENCE
Distributed under the same terms as Net::Server
THANKS
Thanks to Vadim for pointing out the IO::Socket::SSL accept was returning objects blessed into the wrong class.
