Get MAC address using espefuse

[cskilbeck]

Hi, I can get the MAC address using espefuse but it means extracting it from the output using sed or some similar pattern matching tool. This isn't ideal as the format of the output from espefuse isn't guaranteed. Is there a method to get the MAC address in a more defined way?

Thanks,
Charlie.

For reference, the output from espefuse summary contains this fragment:

Code: Select all

MAC (BLOCK1)                                       MAC address
   = ec:da:3b:51:bb:a4 (OK) R/W
CUSTOM_MAC (BLOCK3)                                Custom MAC
   = 00:00:00:00:00:00 (OK) R/W

[/code]

You can try the 'grep' and 'awk' commands.

Sure, but unless the output format is guaranteed not to change then it could break when the espefuse tool is updated.

espefuse is a Python script that you can also use as a library in your own Python scripts. Technically I don't think we promise anything about the API we provide there, but I imagine it's going to be more stable (and visible if it breaks) than parsing the output.

Code: Select all

espefuse.py --port <PORT> summary --format value_only MAC

This will be supported from the upcoming v4.8 release of esptool.
