Hi,
// loop function will be execute by "os" periodically
static void ICACHE_FLASH_ATTR loop(os_event_t *events)

which os FreeRTOS or another?

Start by locating the example that defines the shown loop(os_event_t *events) function and read its surrounding build or platform context. Confirm which operating system or event mechanism invokes it, then document that answer in the relevant example documentation; the issue does not name a file or test.
