| 21 | ((( | ||
| 22 | The HP0D is an outdoor LoRaWAN Gateway. It lets you bridge LoRa wireless network to an IP network via WiFi,Ethernet, optional 3G or 4G. The LoRa wireless allows users to send data and reach extremely long ranges at low data rates. | ||

| 30 | HP0D has passed Helium Full Hotspot Approval. It supports the **miner feature from Helium** and has a built-in ATECC608 encryption chip. It can be used as a Helium Full Hotspot for the project. It also supports Semtech packet forwarder and LoRaWAN Station connection, it is fully compatible with LoRaWAN protocol.HP0D supports two LoRaWAN servers at the same time, **users can use HP0D for helium mining and connects max 2 x LoRaWAN servers at the same time**. | ||

| 98 | ==== 2. Quick Start & Onboarding ==== | ||
| 99 | The HP0D is configured as a Wi-Fi Access Point by factory default. You can access and configure the HPD after connecting to its Wi-Fi network, or via its WAN Ethernet port. | ||

| 102 | |||
| 103 | ===== 2.1 Connect HP0D Web UI ===== | ||
| 104 | |||
| 105 | ====== 2.1.1 via HP0D’s Access Point. ====== | ||
| 106 | At the first boot of HP0D, it will auto generate a Wi-Fi network | ||

| 111 | (% class="box infomessage" %) | ||
| 112 | with password: **//dragino+dragino//** | ||
| 113 | You can use a PC to connect to this Wi-Fi network. The PC will get an IP address 10.130.1.xxx and the HP0D has the default IP 10.130.1.1 | ||

| 117 | |||
| 118 | ====== 2.1.2 Connect via HP0D hostname ====== | ||
| 119 | Connect the HP0D Ethernet port to your router and HP0D will obtain an IP address. If your PC(Windows/Mac/Ubuntu) connect the same network with the HP0D, you can access the HP0D Web-UI via HP0D’s hostname. | ||
| 120 | |||
| 121 | Like: __**//http:~/~/dragino-4ba54a//**__ | ||

| 125 | |||
| 126 | ====== 2.1.3 Connect via Ethernet Port ====== | ||
| 127 | Connect the HP0D Ethernet port to your router and HP0D will obtain an IP address from your router. In the router’s management portal, you should be able to find what IP address the router has assigned to the HP0D. | ||
| 128 | If you get the IP address form route, like~:// (% class="mark" %)**10.130.2.42**(%%),// you can use this IP address to connect the WEB UI or SSH access of HP0D. | ||
