WL1835MOD: MAC address

There is no single default mac address for all WL8 devices, each has its own mac address, made up of a TI designated 3B OUI value (can be searched here: https://www.whatsmyip.org/mac-address-lookup/ ) and assigned NIC value (xx:xx:xx).  It can be changed through the nvs file.  Please take a look at:
