Matter multi admin fails with nrf samples

Question

Greetings, 
 I am trying to pair nRF52840 DK to second admin (controller) using the provided chip-tool and the switch app from the nrf samples. 
 Specs: 
 
 nRF52840 DK (DUT) 
 nRF52840 Dongle (Radio Co-Processor) 
 Raspberry Pi 4 (OpenThread Border Router) 
 nRF Connect SDK v2.1.0 
 Linux Chip-Tool x86 64 
 Ubuntu 20.04 x86 64 VM Controller 1 (uart debug connected to nRF52840 DK) (C1) 
 Ubuntu 20.04 x86 64 VM Controller 2 (C2) 
 
 Following the scenario for commissioning: 
 
 C1: ./chip-tool-release pairing ble-thread 4369 hex:operational-data-set-here 20202021 3840 ,
 
 Device commissioned successfully, visible in OpenThread Border Router, can be controlled by C1

C1: ./chip-tool-debug pairing open-commissioning-window 4369 1 400 2000 3840
 
 [1663682774.140445][29427:29432] CHIP:CTL: Successfully opened pairing window on the device [1663682774.140464][29427:29432] CHIP:CTL: Manual pairing code: [36434149637] [1663682774.140471][29427:29432] CHIP:CTL: SetupQRCode: [MT:4CT91AFN00A7NS7BR10]

C2: ./chip-tool-debug pairing code 4444 36527152093 [timeout, unable to pair] 
 C2: ./chip-tool-debug pairing onnetwork-long 4444 20202021 3840 [timeout, unable to pair] 
 
 Avahi is able to resolve the address.During the second pairing, both C2 and DUT are exchanging messages but fails to establish PASE. 
 Error which i received on chip-tool (C2): 
 [1663682901.400708][3380:3380] CHIP:TOO: Run command failure: ../../src/protocols/secure_channel/PASESession.cpp:245: CHIP Error 0x00000032: Timeout 
 Error which i received on nRF52840 (DUT): 
 E: 1565622 [SC]PASESession timed out while waiting for a response from the peer. Expected messa4 D: 1565632 [IN]SecureSession[0x20003788]: Released - Type:1 LSID:14348 E: 1565638 [SVR]Commissioning failed (attempt 1): 32 
 Expected scenario for DUT: 
 
 Pair with ble-thread to join thread network 
 opened commissioning window 
 pair with onnetwork 
 
 Is there a multi admin (multi fabric) support in nrf samples? 
 Thanks in advance.

Hi, 
 I am unable to pair it using the ethernet or onnetwork, but using the qr-code, it is working fine. 
 I was placing an wrong code for which the device was brodcasting initially. After sending open-commissioning-window, the core is different and unique for this particular window. This was the reason for getting the error. So far it is working fine to me i can continue with the integration.
