Subject: Seeking Guidance on Connecting Mini Bluetooth Keyboard (iOS) to Arduino Mega with HC-05 Module

Hey fellow Arduino enthusiasts!

I hope you're all doing well. I'm currently working on a project that involves creating a text editor using an Arduino Mega and a mini Bluetooth keyboard designed for iOS devices. I'm reaching out to the community for some advice on connecting the Bluetooth keyboard to my Arduino Mega via the HC-05 module.

Here are some details about the components I'm working with:

  • Arduino Board: Mega
  • Bluetooth Module: HC-05
  • Bluetooth Keyboard: Mini, designed for iOS, running version 3.0 class 2

My goal is to establish a wireless connection between the Arduino Mega and the Bluetooth keyboard to enable text input for my text editor project. If anyone has experience with this or a similar setup, I'd love to hear your insights.

Specifically, I'm curious about the compatibility of the HC-05 module with iOS Bluetooth keyboards and if there are any known challenges or considerations I should be aware of. If there's a more suitable Bluetooth module for this task, I'm open to suggestions.

Additionally, if you've successfully implemented a similar project or have tips on configuring the HC-05 module for iOS keyboard communication, please share your wisdom!

I'd also appreciate any recommendations for alternative mini Bluetooth keyboards that have proven compatibility with Arduino projects.

Thanks a bunch in advance for your help, and I'm looking forward to hearing your experiences and suggestions!

HC-05 (and -06) are SPP devices.

So would a different module work or should I scrap the idea and get a wired keyboard?

And rightly too. IOS is the incompatible with HC-05 so it's peripherals probably will be also.
If the keyboard is third party, i.e. "universal", I imagine it is possible. I believe Bluetooth keyboards have been used before.

Sorry, I should have been more clear. Yes, I believe it is a "universal" keyboard. Its manufacturer claims that it is compatible with "HTPC with built-in Bluetooth, Sony Playstation 3, Apple iPhone, Apple iPad, and Windows and Linux Computers." In that case, would the HC-05 still work or would a different module be better?

Thanks

I'm afraid I can't comment further - other than to reiterate that I believe it can be done, and there is a thread around to that effect. I was not involved and only remember this because it occurred to me that a wired keyboard would require a USB host shield on a Mega, while a Bluetooth keyboard would not.
HC-0x can only handle plain-vanilla digital data, but I'm sure that is all that is involved.
