Hi @felmue .
Thanks for the reply. I think I got the solution the same time you sent me yours. I did use the code in here as below:

I did an 'Execute' Block:

import ubinascii import network wlan_sta = network.WLAN(network.STA_IF) wlan_sta.active(True) wlan_mac = wlan_sta.config('mac') wlan_mac=ubinascii.hexlify(wlan_mac).decode().upper()

0_1682625965698_76e881c1-37df-4e5b-94f1-c33c0da572aa-image.png

then a Label Block:

wlan_mac

Anyway, thanks for taking the time and effort to reply.
