homebridge-roomba? I think you are asking in the wrong project

[ilyabreev]

It is used like standalone part of homebridge-roomba without any changes. If I try run same command from this repo, the same problem appears. вт, 16 июля 2019 г. в 20:03, Facu ZAK <notifications@github.com>:

getrobotpwd npm command does not exist on this library.

For me it worked to set the cipher of the TLS connection to AES128-SHA256

[ilyabreev]

@xXKeyleXx Great! How can I set it? And what cipher suite do you mean? TLS_RSA_WITH_AES_128_CBC_SHA?

[scomans]

I modified the script like this:

const client = tls.connect(8883, host, {rejectUnauthorized: false, ciphers: 'AES128-SHA256'}, () => {
    client.write(new Buffer(packet, 'hex'));
});

hey guys what node.js version do you have?

[koalazak]

and what robot? firmware version?

[scomans]

I don't think the node version is the problem. It works fine on my desktop PC but I get this error on my Raspberry PI too.

Node: v12.7.0
Robot: e5
Firmware: 3.4.46-76

[ilyabreev]

I think that problem is in the openssl version. Last openssl doesn't respect such ciphers as AES128-SHA256.

[koalazak]

same problem reported in #91
I will work on a fix maybe hardcoding the cypher to AES128-SHA256
thanks @xXKeyleXx

[koalazak]

hey guys, can you test dorita980@3.1.3 latest version? it should work now

[koalazak]

@xXKeyleXx how are you?
hey, Can you run this node -p process.versions | grep openssl to let me know wich version of ssl is generating problems? I know you had this ssl problems on your box and I want to know which is the bad ssl version.
@ilyabreev can you share yours please?
thank you

[ilyabreev]

pi@raspberrypi:~ $ node -p process.versions | grep openssl
  openssl: '1.0.2n'

[scomans]

openssl: '1.1.1c'
