In these cases having an on-air sniffer log may be valuable to compare;

Hi,

Thanks for your comments. The answer is yes, as of iOS 13, the iPhone now supports a mouse. It's a bit hard to find but go into settings---Accessability---Touch---AssistiveTouch---Devices---Bluetooth Devices and you're there.

I tested it first with an HP bluetooth mouse and it worked fine so I then did it using an Arduino NANO connected to a bluetooth dongle nRF51. This used a BLE library that allowed me to write AT+Commands to the ble module and that also worked perfectly. In fact, by using the extra commands I could even do things that the mouse wasn't capable of including mute the volume etc. However, the new NANO 33 BLE that is based around a nRF52840 chip uses a different ble library and that won't allow me to write AT+Commands. So I have to build up the service and I can get as far as the iPhone seeing the device but cannot cause any actions.

Thanks again

Hi,

I do not believe iOS support mouse pointers, never seen it at least.. You can use keyboard though.
