Well, there are 3 main factors to consider when choosing radio modules: range, energy usage (which is determined by power and the time it takes to connect and send the message) and speed. So using those, the modules you used (plus a bonus) would have: 1. NRF24: medium-high range, low energy usage, high speed. Example usage: drones, battery-operated IoT devices. 2. LoRa: very long range, variable energy usage (depends heavily on the length of the message due to its low speed), very low speed. Example usage: IoT devices. 3. CC1101 without/with power amplifier: medium/very long range, low/very high energy usage, medium speed. Example usage: walkie-talkies. 4. HC12: long range, low energy usage, low-medium speed. Example usage: battery-operated IoT devices, drones. 5. 433 MHz raw: variable range, low energy usage, variable speed. Example usage: cheap devices. 6. HC05/Bluetooth 3.0: short range, medium energy usage, medium speed. Example usage: robots controlled with a smartphone. 7. Bonus: Wi-Fi: short-medium range, medium-high energy usage, very high speed. Example usage: IoT devices, security cameras. IMHO, the best general-purpose ones are the NRF24, the HC12, Wi-Fi (including ESP-NOW) and Bluetooth LE (which isn't in your comparison). They're easy to use (especially Wi-Fi and Bluetooth LE if you use an ESP8266/32), don't use much energy, have a good range and are fast enough for most applications.

Recently I found by accident that for the very cheap 433Mhz modules (with 3 connection pins) if you pull down the data pin with relatively low resistor like 2-5k, the data signal becomes much more stable.

@marcelloziglioli8954

Do you mean the RX pin on the receiver module? Or the data pin on the transmitter module?

@worvtube

The RX on the receiving module, but later I found out that it was not true for every receiver unfortunately.

Thanks for this brief overview of different RC transceivers. 3 important things to add about NRF24: 1) It can also work as transmitter and/or receiver and switch its role on the fly. Example of usage -- binding transmitter to receiver for custom RC. When transmitter broadcasts packet saying he is looking for receiver with required capabilities. And then transmitter listens for inbound packets from receiver with their IDs and other data. 2) The distance, speed and reliability depends on the size of packet. Maximum size is 32bytes. And this will be slowest and less reliable. If you set packet size to 8 bytes -- drammatically improved capabilities. 3) You can change the power of transmission dynamically from your code. Example of usage -- your sensors that need to talk to some hub if something happens. Until something happened -- they don't need any transmissions, so they can set power level to the lowest. On a trigger -- they change power to some more powerful level and transmit new sensor readings to hub. This will allow you to save battery if these sensors are portable. Beside that -- this modules have auto-acknowledge, multi-channels support, etc.

I had so many problems with the NRF24 and never thought the interference would be in the short cables that I was using. I ended up using some more expensive modules for my project instead. I'll do some tests using your twisted cable tip.

I'm so used to always using Bluetooth and WiFi that the idea of using some other radio technology hadn't even crossed my mind! Thanks for this video - it opened up a whole new sea of opportunities for me (much better for my current use case)

Excellent tutorial, been looking for something like this to help with a project.

Thanks for your work. Always like these these test/tutorial videos . 70cm band sounds like you know ham radio.

Great video. I was hoping there would be a video that would compare these different boards and show how they work with code.

That LoRa module seems interesting. Pretty long range! Might be interesting when builiding weather stations, that are further out.

Excellent comparison. I am sure to come back on another date when I am ordering.

Thank for this video and the details for each of the module. Can't wait for the next video😀

As always loved the video I wish I was as clever as you thanks for making it easier to understand

really nice video with good explanations and I like the example code stuff, helped me a lot.

Thanks for the info Electronoobs. Your remote control tank really an inspiration. Now i am able to build an android remote control cars using the HC05 bluetooth module.. keep the video coming..

New intro is awesome 😄 keep doing the good work... 🤘

Very good!!!! For the nrf24l01 you can slow the spi speed to reduce noise.

Thanks for the great review! As a suggestion I think would really nice to perform a range test in the future ;)

Awesome video as always,,, *New Intro* is liiiitttttt 🔥

In general, if you've problems with data signal integrity over such short cables and low data rates, it's probably because the input resistance of the pins is too high and you're picking everything around. Just put there some resistors to strengthen the signal (to increase the current).

Small error in the map use: if you want to map 0-1023 to 0-255, you need to write map(analogRead(pot),0,1024,0,256); It has to do with the way integer-divide works. Try it out, in my example the every 4 values convert to a single value: 0,1,2,3 become 0 and 4,5,6,7 become 2 and finally 1020,1021,1022 and 1023 become 255. But in this case /4 is faster and exactly doing the same.

I love the way you say 'capaciTator' 😄

You're a genius bro. Stay happy wherever you are. It's working bro

your videos always strike a good balance between technical, practical, and useful

I'm using HM-10. In my opiniom its verry good option. All showed modules on your video are diffrents. Every module Lora, Wifi, Bluetooth are used to other projects.

I like the Bluetooth solution.... Would be a good tutorial video if you could show a way to increase the range of the HC-05/HC-06 modules.

Just the video we all needed!

Yes! This is exactly the video I've been looking for!

Thanks for this video and the details for each of the module

I also bought the small version of the 433MHz LoRa but I took like 4 hours to solder everything because it's so tiny !! So I would tell you to buy the module Lora Ra-02 Module So easy to solder ! Buy you will also need to buy 2 IPEX antenna for these Lora Ra-02 modules

Thanks for the great overview of these modules. I've read your tutorials for each module, but I don't see a tutorial link for the HC05 Bluetooth radio. It's okay if there isn't one, but I just wanted to mentioned it in case you forgot to include the link. Good luck!

Nice video. I have used the cheap ESP-01 and wrote some firmware for it. Now I can send and receive serial commands over WIFI (with websockets - uninterrupted speedy bi-directional live connection) in an adhoc private network or in an existing network. It behave like a wire, you don't notice the difference 🙂 I made this for my printers in another room, printers without ethernet or WIFI but can also be used with any Arduino (because my printers are Arduinos). I made this because of a longer range, speed and the possibility to connect between different networks/routers (even through a real ethernet wire! ) and to be able to use older serial software or serial equipment that doesn't support ethernet or WIFI or other wire/wireless tech. For now I am only using serial with this system however it can be anything, video, voice, charts, live chat, calls, interactive commands etc, it could be anything. The nice thing is that you can use existing infrastructure and security for all of your projects. You can make any virtual wire you want and if you want it can go all around the world (internet). The nice thing of the ESP-01 is that it is programmable and you can put any (custom) protocol inside this device without have to repeat all of this protocol and security coding stuff inside your project. Once designed correctly, you can concentrate on the project and features of your project. This will save program space and makes it easier. With this you can make any (tiny) microcontroller wireless. This is a feature all of the other wireless solutions in your video don't have. This is something that makes a real difference. Maybe something to look at. Again, nice video and great accent ;-)

I need to send 64 bytes of info under 50ms, 50 meters away. Can I do that with the ESP?

I have tested NRF24 and HC12. NRF24 haves very short distance about 20 meters (maybe isn't good quality). As result I selected HC12 - it's working perfect.

USB EXTENSION WITHOUT CABLES-ALASKA Nice video, very descriptive. I will really appreciate your comments. I work at the North Slope Alaska during the winter season and we test devices deployed at the field covered by snow / ice. The way to test those devices is using a small computer with a USB cable that is having a special head at the other end (internally this is a USB extension, no circuits inside); this end is attached to the deployed device and the software recognize and test it. The deal is: this software works only using USB port, is no way to select other type of connection. I was reading about all this modules and they converts USB to TTL and TX, USB to Bluetooth and TX or some modules use TTL and TX. Some of this modules allows two way communications, some are recognized as COM port and some work interfaced with Arduino, but no one of this is transparent for USB. That I try to say: Is any way to connect USB (D+ and D-) to a TX and RX pins in a module on one side and RX and TX to the special head connector (D+ and D-) at the other side and at this way simulate a ghost wire? The data string for this test is very short and sure is USB 1 or maybe 2. Again, I will appreciate your comments. Claudio Bio claudiobio2012@gmail.com

Which modul is good for sending voice over 5km?

@originuk

Жыл бұрын

@@worldmusic8941 I might be wrong, but I think none of the modules mentioned here would be anywhere sufficient for voice at any distance... These devices focus on data transfer. If you were to carry a voice over a data connection, you would need to consider the sample rate for voice (5Khz should be enough, and a bit depth of 12-16 bits. Doing the sums, 5000 samples per second, two bytes per sample, means 10 kilobytes of data per second (or roughly 100 kilo bits per second)... so you're looking at needing a baud rate of at least 100kbps (without any error correction protocol, and only half duplex).

This is great and I’m only new to this. I’m trying to understand here as well how many of these modules allow for multiple connections. My understanding is that the NRF24 can allow upto 5 connections per unit. My issue is I have approximately 1.3kms of distance, but I think you can chain the connection between the Nodes to get there.
