I was stuck for a while wondering where the wespi menus were but finally realised I needed to hook up the cassette connection for it to detect the load""
Only other issue I had was flashing the esp32, eventually managed it via the web interface on the manufacturers website. In hindsight and after reading this thread I might have missed ticking the boxes for the flash files in the programmer app
Anyway, what a great project, I'm really happy with it.
