# Multiple Receive Example
|
|
The nRF24L01 has 6 receive data pipes (RX_ADDR_P0-P6).
|
|
In this library, the first data pipe(RX_ADDR_P0) is used for automatic ACK reception on transmission.
|
|
The second(RX_ADDR_P1) to sixth(RX_ADDR_P5) data pipes are used for data reception.
|
|
Therefore, it is possible to receive from a maximum of five transmitting sides.
|
|
This example receive from ```1RECV/2RECV/3RECV/4RECV/5RECV```.
