Modify Embedded C Firwmare Program To Read/Write To Custom GATT Profile Over BLE

We must modify our Embedded C firmware in order to send and receive data over BLE GATT protocol. We have an iOS and Android application that sends and receives commands over BLE to our custom hardware device. Previously we were using Bluetooth Classic but this is not possible on iOS without MFi certification (which we will not get) so we are changing to BLE.
