licensing esp_hosted_fg

Hello everybody,

i recently worked with the https://github.com/espressif/esp-hosted - repo.
I recognized that there are some files (e.g. esp_queue.h) which have the following license identifier:

Code: Select all

 * Copyright (C) 2015-2022 Espressif Systems (Shanghai) PTE LTD
 * SPDX-License-Identifier: GPL-2.0 OR Apache-2.0

What about the "OR" in the identifier? Can i use use it under Apache-2.0 ignoring th GPL-2.0?

Yes. SPDX calls the 'OR' clause a disjunctive license, meaning you get to choose. (In contrast, if it were to say AND, you would need to somehow manage to abide by the restrictions of both licenses; that's called a conjunctive license clause.)
