Wio Terminal Client not working

Hi
Does the example sketch for BLE client work for anyone, using a Wio Terminal?
Or any BLE client code - I have ported mine from an M5 Core and Heltec ESP, and it just won’t work.

I have tried - it doesn’t detect the Service UUIDs for anything.
I can connect only using a MAC address, but then the code crashes on

BLERemoteService* pRemoteService = pClient->getService(serviceUUID);

WiFi works fine, I have installed according the the wiki instructions and flashed the latest firmware.
My M5Core devices find the BLE device fine and connect and read service UUIDs etc.

Does this work for anyone else, or is it just me? Can anyone provide full instructions - perhaps including a reset of the Wio?
Thanks!
