I ordered and received an ESP32 now for my bluetooth experiments.

I want it to connect to my HID device (a Hizek HZ-RM1). A sort of handheld joystick which would be ideal as a remote control.

Alas after 5 hours: no show.

I used/tried the "BLE_scan" example of the ESP32 integration in Arduino IDE. This seems to work (upload and output) but it only finds zero to one devices (maybe from neighbors) but not the ones I am testing with.

My smartphone on the other hand has no problems finding and connecting them...
