BLE Mesh Node Enable/Disable Joining to network with one Button manually

[mm_1993]

Hi All Engineer and Programmers
I use ESP-IDF4.4 and ESP32-C3
in BLE Mesh Example Node ONOFF Server :
https://github.com/espressif/esp-idf/bl ... ain/main.c
in this example, you can find the Node automatically with any BLE-Mesh Apps after powering up.
I want to join and leave the BLE Mesh Network by using a button key manually,
If the Button is enabled, the Mobile App could find the node and vice versa, if the button is disabled, the mobile app could not find the node.
thank you.
