Listener for teensypreter about pateensy

It's just a meterpreter reverse shell, so you can just use that.

Follow through, because I can't get a connect back from the payload. I am using Arduino 1.6.13, Teensy 3.6 board. I have changed the IP address and port for my listener and have removed all the brackets included on the payload. After uploading the payload to Teensy, I have plugged it in, keyboard inputs properly and sends the commands. But no connect back to my listener.

Set the IP address for example, 192.168.254.13 as 0xC0,0xA8,0xFE,0x0D
Port number 4000 as 0x0F,0xA0

Tried using metasploit listeners
windows/meterpreter/reverse_tcp
windows/meterpreter/reverse_http
windows/meterpreter/reverse_https

It should be a reverse tcp shell, however it may be outdated, so I would generate and encrypt new code for the teensy to run and see if the updated version works. Also, isn't Arduino 1.6.13 unsupported by Teensy currently? It shouldn't matter, but you could check by doing what it says in the code manually (you know, ctrl + c, ctrl + v, enter, repeat). Another thing is, have you opened the port on the listening machine, and are you on the same network as the listening machine as using a public ip address for a local machine has been known to cause problems, switch to its local ip address and try again, maybe that will help.

How do you generate a new payload for the teensypreter template? I have done payload generation using metasploit, but in the wrong shellcode format i.e x00\x00\x00\x00 without using any encoders. I apologize, I'm still learning the basics.

I'm trying to nudge you towards a solution that you can find yourself, but your first step is to just generate a payload that works and then test it (without teensy) on your victim computer. You can then make improvements to your payloads, like encoders etc. Really the main thing you want to be improving is code length so your teensy gets it done ASAP. After that you can start transferring your payload over to the teensy. I would just make a new teensy payload from scratch, forget teensypreter. Once you are done, please feel fair to contribute to this repository! With the payload generation, I encourage you to use trial and error to find out what works best for your use case.
