I have developed the schematic of connecting NRF 8001 BLE chip with Arduino,the file is attached that contains the schematic. Can you please verify my schematic i.e will it work or not? If it will work then how would i send data from the iPhone to Arduino. I have seen that you have provided the libraries and i have included them in my Arduino libraries. but still how to communicate with iPhone? I had used BLE shied that is provided by Red Bear Labs and they have provided the separate functions like ble_read() , ble_write() etc. and through these functions i was able to read and write. But now i want to make my own shield whose schematic i have attached. But i do not know how to write those functions and how to communicate with iPhone? Can you help me in these?
