Wireless speaker made using Arduinos and 2.4 GHz tranceivers
[Texane] picked up a 2.4 GHz transmitter/receiver pair for transmitting sensor data wirelessly. After using them in a project he wanted to try pushing them a bit to see what the limits are when it comes to higher bandwidths. He ended up building a wireless speaker that transmits audio at about 90 KB/s. That link leads to a subfolder of his git repository. The code for this project is in the RX and TX folders, with images and video in the DOC folder.
The radio hardware that heís using is a Nordic nRF24L01P chip which is available on a breakout board from Sparkfun. [Texane] mentioned to us that the chip includes error checking, packet ACK, and automatic retransmission. But these add overhead that can slow things down. The chip does offer the option to disable these features to get lower level access to the hardware. Thatís exactly what he did and he mentions that the example code he wrote for the transmitter and receiver make every cycle count. This makes us wonder if itís the speed of the ATmega328 chip that is the bottleneck, or the transceivers themselves?
