I am trying to create an iOS application that communicates with my Atmega 1284 via Bluetooth. I understand that I am restricted to only Bluetooth BLE for my iOS. However, I am having a difficult time finding such devices. I looked into HC-06 and OSOYOO Bluetooth 4.0 HM-10 Master Slave Module for Xbee Arduino UNO R3 Mega 2560 Nano. Can anyone recommend me one and possibly point me to a tutorial? I see multiple tutorials for Arduino but not specially Atmega. Does the same concept apply?
