In the world of wireless Arduino projects, is often hailed as a "silent workhorse" because of its effortless ability to establish long-range, transparent serial communication without the pairing headaches of traditional Bluetooth The Story of the "Ghost Connection"

3.2 Module Configuration (AT Commands)

To enter AT mode, pull the SET pin low (to GND) before powering the module. Send commands via Serial (9600 baud, newline ending). jdy40 arduino example best

Operating Voltage: 2.2V to 3.6V (Note: 5V may damage the module; use a voltage regulator if needed). In the world of wireless Arduino projects, is

Pro Tip: After setting AT+RFNETID, the modules automatically pair. No need for AT+LINK or address targeting. This is transparent broadcasting — anything one sends, all receive. Pro Tip: After setting AT+RFNETID , the modules

To change settings (like baud rate or channel), you must pull the SET pin to GND. Commands must be followed by \r\n (Carriage Return and Line Feed). Simple Wireless Serial Communication - - Notes To Self
