ios - CoreBluetooth and BluetoothManager, device is not BLE

Question

Connect and receive data via bluetooth.

We are developing an app for a client. It is a toy for babies that connects via bluetooth and we're having trouble connecting and transferring data.

After all the research we did, we found two alternatives: CoreBluetooth and BluetoothManager. As far as I know CoreBluetooth only connects with Bluetooth Low Energy (I think it is the latest bluetooth version) and with it I am not able to find my client's device. With the second option, BluetoothManager i can find the device but I can not transfer data.

This makes me think that my client device is not BLE. Is there any way to connect and transfer data with this device, considering that CoreBluetooth doesn't locate the device and only BluetoothManager does?

Could you please provide alternatives and/or examples of how to make this communication? And if you can not do, let me know in order to tell my client.

Answer 1

To communicate with lower versions of Bluetooth you need to use ExternalAccessory framework, but it is for MFi devices, so I guess you need to sign to Apple MFi Program: https://developer.apple.com/programs/mfi/
