# Blinker - UDPv4 Receiver

The UDPv4 receiver module receives a stream using UDP version 4 across a network. It supports the static and dynamic variants of the BLP, EBLP and MCUF protocols.

## Configuration

The configuration of the UDPv4 receiver module with name `NAME` is located in the `udp4receivers/NAME` subdirectory.

### Output Stream

The file `outstream` contains the name of the stream to write the received network stream to.

### Protocol

The protocol to use is configured in the file `protocol`. It can contain the string `blp`, `eblp` or `mcuf` to select the BLP, EBLP or MCUF protocol respectively. If the file is not present, all protocols are accepted.

### Bind Address

The file `bind` contains the local address to bind to. It must contain the IP address and the port, i.e. a string `<IP>:<port>` (hostnames are not supported). If the local address should be determined automatically, the file can contain `0.0.0.0:0`.

### Source Address

The file `source` contains the source address as a string `<IP>:<port>` (hostnames are not supported).
If the source address file exists, only a stream from the specified address is accepted. Otherwise, the stream can be sent from any address.
If both the source address and the protocol are given, dynamic stream request packets are sent to the source address.
