Hello all, My Atreus works great on any Mac, but will not work on any iPhone. No help FAQs to be found on this topic. Any suggestions appreciated! Cheers, Rushwarp ---

Welcome, Rushwarp! Are you trying to connect to your iPhone via lightning/USB? ---

Hi, thanks for your response! Yes, with a USB-C to lightning cable on the iPhone. Dead as a doornail! ---

Same here. Did anyone have any luck with that? ---

On Kickstarter @jesse said he had it working on his iPhone XS. Sounds like he specifically used a usb-c to lightning cable though, I tried a lightning to usb-a with a usb-c converter cable, and it did not work. Edit: just realized @Rushwarp was using the specified cable. Maybe it broke since Jesse last tested it? ---

I was advised by the helpline to use a USB to lightning cable like this: [https://www.apple.com/dk/shop/product/MD821ZM/A/lightning-til-usb-kameramellemstik](https://www.apple.com/dk/shop/product/MD821ZM/A/lightning-til-usb-kameramellemstik) …Because of the way the status of the lightning port is used. I have to order one to do this, but I am watiing becuase I dont want to throw money away for it until I am sure it will solve the problem! ---

Hi folks. Sorry for the slow reply on my side. I’ve been a little…underwater. There are two possible reasons I’m aware of that an Atreus might not appear to work on an iOS device with a lightning port. 1. If you’ve flashed with the latest version of Chrysalis, your device may complain that the Atreus is asking for too much power. There was a build error in the firmware bundled with Chrysalis. That’ll be fixed in the next release, or you can grab the .hex for the mass-production firmware here: [https://raw.githubusercontent.com/keyboardio/Factory-Firmware-Builds/master/Atreus/ATREUS-MP1-RTM/atmega32u4\_firmware.hex](https://raw.githubusercontent.com/keyboardio/Factory-Firmware-Builds/master/Atreus/ATREUS-MP1-RTM/atmega32u4_firmware.hex) 2. You are not using the right kind of adaptor. “Regular” lightning cables, no matter whether they’re Lightning to USB A or Lightning to USB C always treat the iOS device as the peripheral rather than the computer. In this regard, the Atreus is just like any other USB keyboard. Here’s a little bit of third-party documentation about how this works: > **[How to connect an external keyboard to your iPad | Cult of Mac](https://www.cultofmac.com/568793/connect-external-keyboard-ipad/)** > > Hooking a hardware keyboard up to your iPad is easy, and brings all kids of cool features otherwise unavailable.
