Hello all,
I'm about to start a project involving communication between iOS devices and an arduino plugged to a CC2541. I have some questions regarding to this topic and I would be glad if someone can help me to understand better what I need to do to get started.
I understand that the CC2541 includes a 8051 MCU which can be programmed. If I can freely program this MCU then I think there's no need to use an arduino anymore. However I've been trying to search for ways to program the MCU, like IDE, programming languages, etc, but I still don't have clear of what I should use to achieve this.
The communication is going to be done just between two devices, but since not all iOS devices implements BLE, I'm worried about compatibility issues. Would an iPhone 4 or previous version been able to communicate with an CC2541? If not, would an iPhone 4S or 5 be able to communicate with a CC2560? I may be wrong but this module supports both bluetooth 2.1 and 4, doesn't it?
Thank you in advance for all the help you can provide me with.
