Don't work behind my firewall

[Mynogs]

When I try to upload a new firmware to the board wcc tries to connect to the internet to get the description of the boards. So I can not use wcc on some machines with firewalls. The same applies if no internet connection exits. It would help if i can set a local file for the boards configurations. It would also help to specify more options for the internet connection (proxy, other protocols).

I tried different tools but it does not work. If I use the ESP32 Flash Download Tool, where can I find the images for a particular board (in this case M5STACK)?

Hi @Mynogs,

you could easily create a custom "offline" version of wcc. That version would use pre-downloaded local files instead of grabbing them from the servers.

You would need to provide

• the file board.json in source file board.go around line 923 and 988
• the file esptool.zip matching your OS in the source file download.go around line 99
• the file firmware.zip matching your ESP32 device in the source file download.go around line 140
• a lastcommit file matching the new firmware's commit-id in the source file main.go around line 368

If you can implement a clean solution that is 100% compatible to the current wcc and add a parameter, e.g. ' -offline ' to this standard wcc then you could even create a PR so that the functionality would be maintained for you in this project in the future.
