The spec of the Wio Terminal refers to bluetooth 5 but I cannot find any reference to bluetooth in any documentation or samples. From what I can gather this would need an update the the firmware in the RTL8720. Is there any timeframe for this or is this a DIY job.
Bluetooth features, which are still under development, are expected to be released soon.
Also trying to work out whether the RTL8720DN has the BLE5 long range phy. Realtek (as usual) make it hard to find full technical datasheets. (Unlike the ESP32). https://www.amebaiot.com/en/control-mcu/ does not list the RTL8720DN.
