I assume you refer to the Bluetooth Mesh here, as nRF Mesh is a mobile app that neither of these chips support. As for Bluetooth Mesh, the nRF7002 does not support this protocol, as it is a Wi-Fi companion chip specifically, and only supports the Wi-Fi protocol. The nRF5340 supports Bluetooth Mesh though, as does the nRF52 and nRF54 series of Nordic devices.
