Figure 11719: RAK7201V2 Buttons and LEDsButtons
RAK7201 has four (4) buttons, all of which can be configured to execute defined functionality. The stock firmware is configured to send the button's ID number via a LoRa frame whenever one is pressed.
| Function | Description |
|---|---|
| Button 1 | Long press button 1 for three seconds to send a join request. Short-press button 1 to send button 1 data. The data can be personalized with an AT command. |
| Button 2 | Long-press button 2 for three seconds to reset the device. Short-press button 2 to send button 2 data. The data can be personalized with an AT command. |
| Button 3 | Long-press button 3 to display the battery level (blue LED battery indicator1). Short-press button 3 to send button 3 data. The data can be personalized with an AT command. |
| Button 4 | Short-press button 4 to send button 4 data. The data can be personalized with an AT command. |
1The percentage charge is identified by the number of lit blue LEDs. Each LED represents 25% of the battery charge. 1 lit blue LED indicates a 1–25% charge, two lit blue LEDs indicate a 26–50% charge, and so on.
LEDs
There are four RGB LEDs, one per button. The following table shows the LEDs' status:
| Function | Description |
|---|---|
| The battery is charging. | Four GREEN LEDs flash |
| The battery is fully charged. | Four GREEN LEDs light up |
| The button is pressed. | Corresponding BLUE LED will flash once |
| The data transmission is successful. | Corresponding BLUE LED will flash twice |
| The Data transmission is failed. | Corresponding RED LED will flash twice |
| The device is trying to join the network. | Four BLUE LEDs flash anticlockwise |
Interfaces
RAK7201V2 has a standard Micro USB port on the side, that adheres to the USB 2.0 specification. This port is used as both a configuration interface and for charging the battery.
