The max size of the ACK payload depends on multiple transceiver settings, but generally ranges from 5-15 bytes. It can never initiate its own send operation. Second, the receiver can only reply with data after receiving data from the transmitter. First, Automatic acknowledgement packets and ACK payloads must be enabled. The primary receiver can still send data to the transmitter, but there are some requirements when doing this. The primary transmitter can send packets which contain 1 to 32 bytes each. Generally, for a two transceiver system, one transceiver is set up as the primary transmitter and the other is set up as the primary receiver. Arduino is the most common microcontroller used, which this library directly supports. These modules are often used with microcontrollers to provide wireless communication between two or more devices. The nRF24L01+ is a transceiver IC that is often built into cheap transceiver modules. It's built in such a way that it can easily be ported over to other microcontrollers. nRF24L01+Īn nRF24L01 library for Arduino, built from scratch, as a school project. Created by using the datasheet as a reference. Added value: Created a completely new, easily portable library for the nRF24L01+ based transceiver modules.
