## Networking Setup for First-time User ## Networking Setup
Provide them to setup Humpback-DDS: At the moment, both IP addresses of the STM32 board and MQTT broker are hardcoded.
- IP Address of Humpback-DDS MAC address of the STM32 board is also hardcoded.
- Address block of the local area network
- MAC Address of Humpback-DDS
- IP Address of MQTT broker
- Device name of Humpback-DDS
Note: ### STM32 IP Address
- IP/MAC address of Humpback-DDS should be unique inside a local area network. IP address is hardcoded in the file `src/main.rs`, line 171.
- Device name should be unique among all Humpback-DDS connected to the same MQTT broker. ```rust
- The MQTT broker must accept TCP connection at port `1883`. store.ip_addrs[0] = net::wire::IpCidr::new(net::wire::IpAddress::v4(192, 168, 1, 200), 24);
Use the following Nix command.
```shell
openocd-flash-customised <client_cidr_ip_addr> <mac_addr> <broker_addr> "<name>"
``` ```
Parameters: The IP address shown above corresponds to `192.168.1.200`, in a `/24` address block.
- client_cidr_ip_addr: IP address for the Humpback-DDS device, in CIDR notation Modify this line to the change the IP address of STM32 board.
- mac_addr: MAC address for the Humpback-DDS device
- broker_addr: IP address for the MQTT broker
- name: Device name of the Humpback-DDS
### Example ### STM32 MAC Address
```shell IP address is hardcoded in the file `src/main.rs`, line 156.
openocd-flash-customised 192.168.1.200/24 AC:6F:7A:DE:D6:C8 192.168.1.125 "Urukul" ```rust
let mac_addr = net::wire::EthernetAddress([0xAC, 0x6F, 0x7A, 0xDE, 0xD6, 0xC8]);
``` ```
The device will be named `Urukul`. The MAC address shown above corresponds to `AC::6F::7A::DE::D6::C8`.
It has `192.168.1.200` as IPv4 Address, inside a `\24` network, with `AC:6F:7A:DE:D6:C8` as MAC address. Modify this line to the change the MAC address of STM32 board.
It will connect to a MQTT broker at `192.168.1.125:1883`.
### Broker IP Address
IP address is hardcoded in the file `src/main.rs`, line 241.
```rust
IpAddr::V4(Ipv4Addr::new(192, 168, 1, 125)),
```
This program will try attempt to connect to `192.168.1.125:1883`.
Modify this line to the change the IP address of MQTT broker.
Note that the broker must accept TCP connection at `port 1883`.
