GPIO Wake has no affect on example (TZ-1516)

[asward]

Answers checklist.

• I have read the documentation ESP Zigbee SDK Programming Guide and tried the debugging tips, the issue is not addressed there.
• I have updated ESP Zigbee libs (esp-zboss-lib and esp-zigbee-lib) to the latest version, with corresponding IDF version, and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

5.4

esp-zigbee-lib version.

1.6.2

esp-zboss-lib version.

1.6.2

Espressif SoC revision.

ESP32-C6

What is the expected behavior?

I expected to be able to modify the sleep example to use gpio_wakeup_enable and esp_sleep_enable_gpio_wakeup.

What is the actual behavior?

It doesn't wake up on GPIO.

Steps to reproduce.

1. Clone example code (https://github.com/espressif/esp-zigbee-sdk/tree/main/examples/esp_zigbee_sleep/light_sleep)
2. Modify

80,81c80,81
<         ESP_ERROR_CHECK(esp_sleep_enable_ext1_wakeup(1ULL << CONFIG_GPIO_INPUT_IO_WAKEUP, ESP_EXT1_WAKEUP_ANY_LOW));
<  
---  
>         ESP_ERROR_CHECK(gpio_wakeup_enable(CONFIG_GPIO_INPUT_IO_WAKEUP, GPIO_INTR_LOW_LEVEL)) ;
>         ESP_ERROR_CHECK(esp_sleep_enable_gpio_wakeup()) ;

3. idf.py flash monitor
4. Toggle CONFIG_GPIO_INPUT_IO_WAKEUP (defaults to 7 for C6)
5. No wake.

More Information.

Also observed:

1. With original config the wake reason is always (0) other, and randomly (4) timer
2. With original config the system wakes constantly (~50-100ms). It's difficult to determine if the ext pin is waking the chip or something else (ref 1 above).
3. With GPIO config it only wakes with (0) other but is always at the pre-set ED_KEEP_ALIVE time, which makes me think it's just the timer.
4. Changed to GPIO9 (C6 BOOT button): ext breaks (I think GPIO9 is not an RTC gpio on C6), but GPIO wake also does not work.

Hi @asward ,

This is a system issue and not related to Zigbee. I believe it can be resolved more quickly if you submit an issue here.

[asward]

I will open a ticket in the idf project.

For what it's worth, an older issue on this thread seems to have been resolved in April. #99 (comment)

The esp_sleep_enable_gpio_wakeup() functionality works flawlessly without the zigbee sdk.
