1- With the iOS device, are you plugging into the "USB to Host" port on the module, then into the camera connection kit with the opposite end of the USB cable, then plugging the lightning end into the iOS device?
Hi Jordan, thank you for your answer.
I don't own a camera connection kit, which might have been the issue concerning the IOS setup. I had not see it indicated anywhere that it was needed prior to your message, so I'll buy one and confirm whether it solved my issue or not.
I made sure to use a short USB 2.0 cable - as per page 58 of the manual, the cable must be less than 3 meters long, and USB 3.0 cables cannot be used.
Hi Georger, thanks for the answer. Sure enough I hadn't seen that particular line, or must have forgotten about it when buying the cable in the store, because I just checked and the cable I bought then is a 3.0 one. I'll make sure to change the cable and try again.
Will confirm whether or not these changes solved my issue, thank you both for your help !
