esp_zb_set_extended_pan_id has no effect (TZ-980)

Question

Hello
I'm facing the same issue as described in issue #81 : setting the extended PAN ID on the ED (end device) seems to have no effect.

The situation is :

• I'm using two ESP32C6, respectively as coordinator and ED, both running ESP-IDF v5.2.2
• the coordinator is started, the signal ESP_ZB_NWK_SIGNAL_PERMIT_JOIN_STATUS is sent, with an open time of 180s. So I understand it is ready to accept joining from devices
• when the ED starts, I set the ext. PANID to the value read on the coordinator
• but the ED does not join : esp_zb_get_extended_pan_id() still returns the ED mac address and I'm getting a signal 'NWK Permit Join', as if the ED were waiting for another to join ...

Enabling the trace :

• on the coordinator : Network steering successfully started (Extended PAN ID: 40:4c:ca:ff:fe:44:82:f4
• on the ED : ZBOSS: nwk/nwk_join.c:629 Rejoin failure: no dev with xpanid 40:4c:ca:ff:fe:44:82:f4 or can't choose best parent

So my questions are :

1. is this call correct ?

    esp_zb_ieee_addr_t ext_pan_id = {0xF4, 0x82, 0x44, 0xFE, 0xFF, 0xCA, 0x4C, 0x40}; // 40:4c:ca:ff:fe:44:82:f4
    esp_zb_set_extended_pan_id(ext_pan_id);

2. must I also call esp_zb_set_pan_id()
3. when should I do these calls ? They are currently inside case ESP_ZB_BDB_SIGNAL_DEVICE_REBOOT:

Thanks in advance for any clue.

Additional context.
