From the hardware side, the RAK10701-H and the WisMesh Tap are identical (GNSS modules are compatible if your RAK10701 still has the “old” RAK1910).
From firmware side, the RAK10701 is based on RUI3. To convert it to a WisMesh Tap, you have first to flash Arduino Bootloader on the device following this guide.
Then flash the Meshtastic Firmware. But I don’t see the Meshtastic firmware for the RAK10701 in their official releases (no idea why, it is not in our control).
If you want to do it, you need to compile the firmware from the Meshtastic sources for the RAK10701. It is listed in their platformio.ini file.
