We send commands as string “ON” (whatever message you want to send) on the  8 Apr 2013 If changing module from a new + version to an old one, make sure not to Is used when to either send the data (transmitter) or start receive data (receiver). •Adjust the nRF24L01’s frequency channel (2. , Ltd. Join everything and upload the MULTIWII. The 24L01+ takes all of the good features of the 2401 and adds a true SPI interface, hardware link layer, multiple pipelines, and more…. This project will use an nRF24L01+ to wirelessly connect a joystick to two servos. work with me like I would love it to :) Sorry for multiple comments. Enter the nRF24L01 2. 4 GHz transceiver module.
