Figure 11657: RAK7201 buttons and LED- Buttons
RAK7201 has 4 buttons, which all can be configured to execute defined functionality. The stock firmware is configured to send the buttons ID number via a LoRa frame, whenever one is pressed.
- LEDs
- Blue LEDs
There are four blue LEDs, one per button, which light when a press occurs.
| Status | Function |
|---|---|
| Flash once | The button is pressed. |
| Flash twice | The server received button information correctly. |
| Four LEDs flash clockwise | Joining the network. |
| Four LEDs flash for 1s | Joining to the network is successful. |
| Four LEDs are lit up | RAK7201 is in configuration mode. |
- Red LED on button 2
The red LED on Button 2 indicates the charging status of the RAK7201.
| Status | Function |
|---|---|
| on | The battery is charging. |
| off | The battery is not charging. |
- Red LED on button 4
The red LED on button 4 indicates the network related information.
| Status | Function |
|---|---|
| Flash for 1s | Joining to the network failed. |
| Flash for 1s after a button is pressed | Not connected to the network. |
| Flash twice | Transmission failed. |
Interfaces
