Receiver Configuration Guide
This guide provides detailed instructions on configuring the DFRobot Gravity digital wireless switch receiver, including mode switching and pairing techniques, helping users optimize their receiver setup for varied applications.
The receivers in this tutorial all take DFRobot's Gravity: digital wireless switch receiver (433MHz) as an example. The principle is similar when using receivers from other vendors.
Mode Switch
The receiver is in inching mode by default. The following examples all take inching mode as an example. If there is no special requirement, you can skip this step.
| Mode | Description |
|---|---|
| Latching | After D0 receives the signal once, it stays high until D1~D3 receive the signal |
| Self-locking | Each time D0 receives a signal, the corresponding output state is inverted once, the same is true for D1~D3 |
| Inching | D0 receives the signal and outputs high level, but does not receive the signal low, the same is true for D1~D3 |
| Interlocking | When receives the signal D0, D0 stays at a high level, and all the others are low. The same applies to D1~D3. |
Press and hold the button for 0.5~1.5 seconds, then release it, the blue indicator light flashes twice, indicating that you have entered the mode switching state, and then you can enter different modes according to the different times of pressing the button within 6 seconds:
Press once to enter the latching mode;
Press twice to enter the self-locking mode;
Press 3 times to enter the inching mode;
Press 4 times to enter the interlocking mode;
According to the mode you need to enter, press the button for the corresponding number of times, and then hold the button for 0.5~1.5 seconds as a confirmation signal. After letting go, the blue indicator light flashes 2 times to set successfully and enter the corresponding working mode. 0.5-1.5 seconds is relatively short, be careful not to press overtime.
Clear pairing
The receiver can store up to 32 sets of transmitter codes. When there are more than 32 sets, the first paired code will be overwritten;
Clear all paired transmitters: Press and hold the button on the receiving end for more than 4 seconds. After releasing your hand, the blue indicator light flashes twice to successfully clear all paired transmitters; if the clearing fails, repeat the above operation.
