Which version of librairies do you use?

Unfortunately no. I did an upgrade of the esp idf, an upgrade of all librairies, I did not manage to make the router mode work.
Zigbee on esp32 is a bit mistery

I lowered the tw_power of the sonoff coordinator, the zigbee network joins only the nearest esp32 endpoints, not the far esp32. It confirms that the router mode does not work. I think there are bugs in the libraries

worked after a few changes.
Maybe this change of channel mask in the .h succedded? I am not sure
//#define ESP_ZB_PRIMARY_CHANNEL_MASK (1l << 20) /* Zigbee primary channel mask use in the example */
#define ESP_ZB_PRIMARY_CHANNEL_MASK ESP_ZB_TRANSCEIVER_ALL_CHANNELS_MASK

Hi,
I developped an iot based on esp32-h2. I have 5 esp32-h2
Network is zigbee
Each esp32-h2 is configured in router mode:
in menuconfig zigbee device type is set to "Zigbee coordinator or router device"

In the code I put:
esp_zb_nwk_device_type_t device_type = esp_zb_get_network_device_role ...
