Using Zigbee host example, but "esp_zb_lock_" functions are undefined

[MX682X]

I'm using the ESP Thread Zigbee Gateway board (ESP32-S3, running esp_zigbee_host and ESP32-H2, running esp_zigbee_ncp example).
Using Visual Studio Code with the ESP-IDF extension (v5.4.0). Ubuntu 24.04.
I wanted to expand the host example and send custom commands and I tried using the esp_zb_lock_acquire() and esp_zb_lock_release() functions, like mentioned in the documentation, but those functions are undefined.
I tried finding a definition with grep, but haven't found anything either.

Does someone know how to fix this?

Hi @MX682X,

The esp_zb_lock_acquire() and esp_zb_lock_release() have not defined by the esp_zigbee_host. Since the esp_zigbee_host only includes the Zigbee application layer is designed as thread safe, it does not need the lock to protect the resource of task, which is different with other examples. So, you can send custom commands in ISR or other task without the lock protect.
