NRF24L01 channels

RF Channel Frequency. The nRF24L01+ transceiver module transmits and receives data on a certain frequency called Channel. Also in order for two or more transceiver modules to communicate with each other, they need to be on the same channel. This channel could be any frequency in the 2.4 GHz ISM band or to be more precise, it could be between 2.400 to 2.525 GHz (2400 to 2525 MHz) nRF24L01 Six Channels To One Receiver Posted on May 25, 2010 by itead & filed under Application Notes. nRF24L01 supports multi-channel data receive, so you can use several nRF24L01 node to transmit data to a terminal receiver. We have built a sensor network demo, which use 6 sensor node and send the data to one receiver The nRF24L01 channel spacing is 1 Mhz which gives 125 possible channels numbered 0.. 124 The nRF24L01 channel spacing is 1 Mhz which gives 125 possible channels numbered 0.. 124. WiFi uses most of the lower channels and we suggest using the highest 25 channels for nRF24L01 projects. Transceivers like these both send and receive data in 'packets' of several bytes at a time The nRF24L01 internally uses pipes as a method of separating data from different devices into distinct feeds that you can read from. It is merely for convenience. You can open up to 6 pipes at once, each one receiving from a different address. All pipes are in the same channel though since you can only tune to one channel at a time

Es handelt sich meistens um Transceiver. Bluetooth kommuniziert über AT-Befehle. Der NRF24L01 ist ein ganz besonderes Gerät mit geringem Stromverbrauch, das über mehr als hundert Kanäle usw. verfügt, jedoch ein einzigartiges proprietäres Protokoll ist. Bluetooth ist ein Standard für die drahtlose Kommunikation, und so weiter. Für einen Benutzer hingegen ist es vielleicht interessanter, wie einfach oder schwierig das Einrichten und Programmieren der Hardware des Geräts ist nRF24L01 is an RF wireless signal chip radio transceiver module for 2.4 GHz ISM band. NRF Module has an inbuilt fully integrated frequency synthesizer, power amplifier, crystal oscillator, demodulator, modulator, and enhanced shock burst protocol engine. It has built-in power down and standby modes which makes power saving realizable. The module is easily programmable through SPI interface and. What\'s more, this nRF24L01+ module is designed with Power amplifier and SMA antenna This allowed you to use the wireless communication up to 1000 meters! (No barrier) Specifications: Frequence: 2.4GHz~2.5GHz Operating voltage: 3 ~ 3.6V Max Current: 115mA Multi-frequency: 125 frequency Support up to six channels of data receptio The nRF24L01 is a single chip radio transceiver for the world wide 2.4 - 2.5 GHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and Enhanced ShockBurst™ protocol engine. Output power, frequency channels, and protocol setup are easily programmable through a SPI interface Als nächstes arbeite ich daran, einen NRF24l01 an einen WEMOS D1 mini anzuschließen. Das D1 mini hat zwar von Hause aus ein eigenes 2,4GHz Sende- und Empfangsteil, benötigt zum Betrieb aber immer ein funktionierendes WLAN, was man nicht immer zur Verfügung hat, oder aus gewissen Gründen nicht nutzen möchte. Es gibt verschiedentlich Informationen dazu, aber wie gehabt, alles irgendwie.
