It would be great if you can explain how changing the hardware to BLE and iOS UDP background requests are related

Our app is connected via bluetooth to a device and the device's proxy sends IP packets which should be handled by our app and sent to the server.. This is the use case. Right now we do it for TCP and UDP packets. Was looking for a way to do the same for IP packets. Main functionality would be just creating a connection to the server, send IP packets and receive IP packets from the server and send it back to the device.

@Hoffman from what I understand, TCP or any transport protocol packet (with header) is added as data in IP packet. So can't we just extract the data part and send it ?
