I've recently been doing a project using these nrf modules. I was using the green ones that are 10 pin. They just have extra Vcc and GND pins that seem redundant. When I tested them I got about the same range through walls as you said roughly 15-20 at a guess. I then tested them outside with direct line of sight and got 41 metres before I ran out of space. For anyone else going to use these, you can download the nrf library from within the Arduino IDE. It just makes things a bit simpler as you don't have to go and find the library online and rename it etc. They are decent little modules when they work.

Julian Ilett I believe you can enhance the reception of the transceivers by soldering a wire to the exposed copper tracks (which I believe to be the on-board antenna) to a metal coil or WiFi antenna it increases the range of about 4-5x depending on the metal used for the antenna. It does reach a range of up to 2000 feet when it's on line of sight.

Julian, another interesting and informative vid. Good info on libs, code and module functionality. The higher the freq, the more arial orientation comes into play with blocking and reflections introducing beaucoup effects. Best signal strength for this 'meadering' type antenna is with antenna's Z axis pointing at non-blocked sig source with no reflections to mix out-of-phase sig w sourse sig. If sourse is blocked, search for a reflected sourse like your fridg's door.... Laying the Tx module on the kitchen floor focuses most, but not all, of its Tx energy at the ceiling. Regards and keep up your good work. Its always of value! Regards/73 Russ in NH/KA1RUW

Fascinating side note, who knew the CH340 carried the 3v3 vreg duties. 200mA or less I would imagine. Is this a standard method for that second voltage. Do some knock offs have dedicated SMD like an AMS1117 3.3 offering a little more robustness therein. It is a very nice version of the Uno with the double gated I/O headers. Not an easy find these days to be certain. As per usual a very enlightening Illet production. Best regards

Hey Julian Ilett - Maybe you could try adding on more wire to the end of the antenna just to see the results? Its a test I want to try on mine when I get some time. Off the top of my head I think the 1/4 wave antenna on the board should be about 31mm- maybe try adding wire to take it up to half, 3/4 and full wave :) Might be a cool test if you still have them set up. Would love to see the effect on range. Cheers! Eric

Eric William Julian Ilett The NRF24L01+ is an amazing little chip, we got over 300 ft inside, and didn't seem to have a power issue, but what we have is a slightly different version of the one pictured. The drop off seemed to be around 320 - 330 ft for us. We were in a rather large area, that was mostly open, but had metal rack units every few feet. so a bit better then the norm for these. which is around 200 feet the day could have just been right for it too....or the fact that nothing was really in the way www.hobbyking.com/hobbyking/store/uploads/820169487X569826X26.pdf

Not sure what the extra 2.5cm silver part is for at the end? This is supposed to be good for 80m but I've never tried anywhere near that far because the quadcopter it came with is so small I can't see which way it's facing after about 20m!

Nice walkthrough. I am using Mini Pro clones, which don't have 3.3v regulators, so before I decided to go buy some regulators, I decided to go dumpster diving in the e-waste, and I took apart quite a few things. I found several 5v regulators but I didn't find much at all in the way of 3.3v regulators. Seems everyone is making switching power supplies these days (or filtered big old transformers, in the older days), but not too common to find the 3.3v regulators. Finally I decided it wasn't worth finding these, and bought a pack of 10 of the knock-off base modules for like $4.50 from china ... cheaper than dirt, I shouldn't have wasted my time in the dumpster. Except now I need to wait for shipping. =\

@ShaunHusain
@ShaunHusain 8 жыл бұрын
Arsalan Iravani Having a capacitor between ground and the vcc on the rf board is the important one if one is already on the module it should be fine. The capacitor between vcc and ground allows some charge, up to the input voltage, to accumulate in the capacitor then if the circuit momentarily draws more current than the supply will allow to flow (because of resistance) then the power will come out of the capacitor instead of the processor or other components not having enough power to operate normally. having one for the Arduino input if your power source can't handle the draw at times helps as well.

Question: Can I bind one of these NRF24L01 modules to my old toy remote control? ......How?. I have connected it to the arduino, loaded a program I found in the NRF24 library that is supposed to "Listen", with no results. When I start the Remote control, However, it beeps like it did pair up, although it behaves like it didn't, and the program stays like in a loop trying to find the signal. Can you help?

We will need the details for the toy remote you are using to help. Depending on the frequency, chip type, compatibility etc it would theoretically be possible although it might be more work then necessary.. If your toy remote is relatively simple (ie not many outputs/channels) you may be better off pairing two of these RF24s' and building your transmitter and receiver around these chips. Is your toy remote 2.4ghz ? If so it is theoretically possible. Sorry I can't be more help :( but leave me some details and we can maybe help you out. Cheers

What happens if you solder a piece of wire to the PCB antenna? Are antennas that simple or size/length/shape need to be fine-tuned for any improvement at all to be observed?
@Aleksanti
@Aleksanti 8 жыл бұрын
No, you cant just solder a wire to a pcb antenna. Antennas are tuned, and they need to be designed very carefully. A lot of math goes into designing an antenna. By soldering a wire or even touching an antenna you are effectively changing its inductance and capacitance thus changing the resonant frequency. :)

Built this, as I had a couple of them from Banggood kicking around in my "Curiosity Box" - where I use up the last couple of quid in my PayPal account. Had a Nano, and some 3.3V Pro Mini's, the latter I buy like candy. Set it all up, then realised I'd connected 5V to the radio module. S H one T! It SURVIVED! I put one pot. on the transmitter - Analog0 on the nano, and used the exact same code. Analog1 was floating. Nano mounted on a similar breakout board aas your setup. Here's weird....the readout dutifully showed Analog0 tracking 0-1023 nicely, but Analog-1 closely tracked it, until I grounded Analog-1. Reckon the Chinese don't clean the flux off their boards thoroughly - must've been the extreme impedance of the analog pin, Wasn't capacitive, else it'd (A1) have changed over time. Bit of a caveat there, if folks are getting odd readings on their analog readouts.

If you look carefully at the video, you'll see a tiny three-pin surface mount chip on the Uno clone, labelled 662K. That's a voltage regulator whose purpose is to drop 5V to 3.3V at up to 200mA . I suspect that may be the actual source of 3.3V - there wouldn't be much point in having it on the board if the CH340G was capable of making 3.3V available.

Good result.... I used exactly the same online resources. Have you tried the Interrupt driven examples yet? Handy when you want confirmation that a message has been received.... I want to use these to send notification of one-shot events (cat-flap open, pir triggered, bomb dropped, etc) so, as a test, I left a pair of these chatting to each other overnight, one message every 300ms with a small oled displaying message counts. The result was that about one transmission in six didn't make the trip, probably a result of my shocking code as distance didn't really affect the result. Easily fixed though by checking for failures and resending. Great little modules despite their annoyingly breadboard unfriendly footprint. I splayed the pins out on a couple and soldered them to some IC sockets to use them directly on breadboard. Cheap and cheerful fix. :o)

Are the RF24's signal 5V proof? I can't seem to find it in the sheets. That it works witth 5V signals without smoke combing out is obvious :)

hi !!!! i've got my module to work but it works fine at 5cm apart and after that the recieve signal are lost what's wrong with that i have powered my modules from the board and added a 10uf cap in parallel !!! i can't figure out whats the problem

Monitor your 3.3 volt supply. If you have a scope even better. It does look like your 3.3 volt supply does not have enough current available or too much voltage drop in your wiring.

Julian Ilett , could you please make a project , if possible, on how to use the stc15f204lea breakout boards as an SPI to UART converter for the NRF24L01+ to directly connect the RX and TX wires(of stc15f204lea) to one arduino. You can also reply me the way to do so, i.e; starting from flashing the stc15f204lea with the hex file generated from a code using the appropriate software. Thanks in an Advance.

Can you connect the nrf24l01 to the icsp pins on the Arduino so that I can get more digital pins?

Hocam selamlar. Kullandığınız kondansatör kaç uf? Ben 10 uf kullandım ama sonuç alamadım. Kütüphane ve Kodlama da sorunum yok. Derleme tamamlandı diyor. Fakat iki modül birbiriyle veri alışverişi yapmıyor.

Hello, Thanks for nRF24L01 Examples using the RF24 Libraries, I want to know, if it's possible to send and receive data every 10 ms ? (delay 10)

Another awesome video. I have been a subscriber of yours for a while now and have learned so much from you. I am curious if you would be open to doing another video on the nRF24, Specifically Example Remote_led by maniacbug. I am new and am having trouble understanding some of the code in this example.

why have you used this additional capacitor? What for?

+Szalony Naukowiec Many places that discuss the use of this module recommend it. The radio module transmits in short bursts, during that time the module draws a spike of power from the 3.3v power line. This can cause the supply to dip and possibly cause interference with other components or intermittent behavior of the radio. The capacitor smooths out the power.

Hi +Julian I'm looking to build a wireless kind of headset using the Arduino. I was wondering if this set will converting the analog signal from let say my iPod to a digital data that will be then received by the receiver?

Reni I am using 2 different controllers. Pololu A star32U4 and Arduino Uno. I use 1uF and 4.7uF (Uno). They are not talking. The monitor says "no radio available" How do you test the radio if they are not working? is there an phone App to test communications

hi nice video. I'm using nrf24l01 for my project but I need to transmit 6 values from 6 sensor. The problem is that I should add a delay (500) on receiver algorithm ether wish it doesn't work and it says no radio available? how I could fix it ? thanks

Hey great video, i have a question, do you know how to activate the nrf24l01 without a library in assembler, i managed to make the spi communication between two p16f877a but not with the nrf24l01
