esp-idf-ssh-client

ssh client for esp-idf.
You can use the ssh API to execute remote command.
This project use this ssh library.

Software requirements

ESP-IDF Ver4.4
This is because this version supports ESP32-S3 and uses mbed TLS 2.28.1.
ESP-IDF Ver5 has been updated to mbed TLS 3.x.x, but this ssh library does not support mbed TLS 3.x.x.

Reference

https://github.com/nopnop2002/esp-idf-scp-client

You can use scp and ssh to do heavy processing that esp32 alone cannot.

• Copy file from esp32 to remote using scp-put.
• Execute remote command using ssh-client.
• The processing result is redirected to a file.
• Copy file from remote to esp32 using scp-get.

For example, image processing:

• Take a picture using the esp32-cam.
• Send image files to remote using scp-put.
• Image processing such as shading is performed on the remote side using scp-client.
• Receive image file from remote using scp-get.

This also works with ESP-IDF V5.X.
