Zigbee.openNetwork() permanent join? (ESP32 Arduino Zigbee)

[rabistel]

Hi!
I’m using the Arduino ESP32 Zigbee stack with my own coordinator.
I found Zigbee.openNetwork(uint8_t time).

What value for time keeps the network permanently open? Is there a way to open the network indefinitely?

Can End Devices that use deep-sleep perform a secure rejoin without opening the network again? (I know it’s possible in light-sleep but light-sleep has higher consumption.)

Thanks!

Hi, for security reasons the Zigbee network should not be permanently open. I did not test, but you can give a try and call Zigbee.openNetwork(0); to be permanently open, but no clue if that gonna work.

If end device uses deep_sleep, after reboot it will rejoin the network if it's closed, I don't see any issue why it should not. No need to open the network, if the device was already connected (commissioned) before.

Hi! Thanks for your reply and the explanation. I’ll test this, because I honestly don’t know yet how the Arduino ESP32 Zigbee stack behaves with secure rejoin after deep-sleep.
Since deep-sleep is a full reboot, I want to verify if the stack correctly restores the network context and performs a rejoin without requiring openNetwork() again. I’ll report back with results.
