TruePatrick:
Can we assume that the NRF module is broken?
The only way to be sure is to try another nRF24 module in its place - it's much less likely that two of them would be broken.
I had to because, the program was in the setup function which is performed only one time, and I don't have time to open serial comunication to take a look at the results. I don't know any other way.
Press the reset button ?

Robin2:
Press the reset button ?
You always find something you don't know, I guess;)
raymw:
But, you really should, start from the beginning again, with getting Robin's exact code working. By 'exact code', I mean cut and paste it. But, it may not be too easy with those particular nrf units.
You're right. I'll check on your code and try to work on it. Thanks!
Today's my birthday and I feel more like it to work on this matter. I have an idea to work on, but I need your help.
I have some leftovers of HT7333 modules, which regulate the voltage from 5V to 3.3V. People use them with NRF modules. Can this one work? Here's the scheme.
I can build this using protoboard and some soldering skills. Surely, I am certified IPC specialist;))
(I think I will go buy some capacitors 10/100uF, because I think mine is broken - I found out about that building simple system with led which should fade but does not, when the main battery is off)
TruePatrick:

If I have read it correctly the datasheet says that their max output current is 150mA. That may be on the low side. I have used LD1117 / LD33 regulators which have a max output of 800mA.

Robin2:
If I have read it correctly the datasheet says that their max output current is 150mA.
Found HT7333 documentation. Max output 250mA.
According to this site,Receive Mode Current(peak): 45mA. Also, I think that the modules will operate at LOW_POWER settings, because I will use this car only at home (At least for now. Max few meters away). Should I give it a try and start soldering?
But anyway, I need to buy new capacitors. May take me few days.
Quick edit. The controler that I've built, using this tutorial uses this HT7333 transistor as power regulator for nrf, so I think the person that designed it was not wrong.
TruePatrick:

I must have read the wrong line.
Either way it is certainly worth trying if you already have the devices.
Get the nRF24 working with a pair of AA alkaline cells and then disconnect the battery and try the voltage regulator.
...R
iI you are buying stuff, happy birthday, btw, and if you intend future projects, then get at least a few of the nrf modules with the pcb antenna, and a couple of adapters. e.g. adapters - any like this
and nrfs like this
https://www.amazon.co.uk/s?k=PIXNOR+5pcs+Professional+NRF24L01+2.4GHz+Antenna+Wireless+Transceiver+Module&ref=404_search
(not necessarily from those suppliers) I found that the longer range nrf's with external aerials, as I've said before, do not work well at short range.
The adapters make it much easier/reliable for breadboard experimentation, and can be dispensed with in the final pcb. You can then test out Robin's software without having to be concerned with distance, aerial orientation, voltage regulators, etc.
The smaller nrf units work fine within a few inches of each other, or much more, the other more powerful nrf units do not, in my experience. Then, try it with your more powerful nrf's, see if there is a benefit in your application, etc, etc.
This guy got NRF24 with antennas, and managed to get to communicate them less then meter away:< I see that he's using this adapters that you've mentioned about.
My plan is as follows:
-buy new capacitors: 10/100uF (but what voltage, previously I got 25V, the circuit operates at 6-10V. Does the voltage matter as long as it is above 10V?)
-buy NRF24 short range (without antenna). In case of this one is broken. Can this short range module communicate with long range?
-buy 1 adapter for the receiver. I can not use adapter for the transmiter, because there's no room on the controller to fit it. 2 Capacitor should do a thing.
I guess It should be all right. Will talk to you in 2 days or less. Thank you that you're with me.
TruePatrick:
Can this short range module communicate with long range?
Yes
...R
if you are using the adapters, you won't need the capacitors, but the voltage you quoted should be OK. I hope you don't buy only one of the small nrf24, or one of the adapters. The idea is that you make up a Tx and an Rx unit as specified by Robin, and test out his software. Once you/we are happy that is working, then try the longer range units - they will just plug in, no software changes necessary. Move 'em around a bit, adjust aerial angles, etc. Then, you know you've a working system, and components, Then piece by piece fit/change it to suit your application. It would be nice if you didn't have to dismantle the test set up.
A nice video you linked to, but ignore it for the time being. I'm not sure what he meant by it working, I heard no buzzer. I'm not saying the long range units do not work if close to each other, but not reliably. It depends on many things. The units you will be buying will work at close range, and certainly will be OK in your car if in same room. Once the test is working you can dispense with the adapter, most likely power via the arduino. I explained that in my post #19, above. wrt the way that worked for me, (it also mentioned that the more and less powerful units work together) it was a 'work towards' result, making small changes on the way, and testing each step. (but you can do it better with your 3.3V voltage regs...)
It took me a while. But my days seems brighter as things start to work.

I think, It indicates that there's something wrong with the transmiter. I tried thinking of many ways. Here are my 2 thoughts:
Why are there all the garbage characters in the "long range" connection test? I would not be happy with even one of them.
There are 5 pins to upload the code to the arduino using USBasp programmer. When I normaly, upload the code, I use all 5 pins. When the code includes Serial.print command, I disconnect VCC and GND pin, and switch ON external power supply 8V for the arduino. For that the module gets full 3,3V power and can work "properly", and the arduino can still send signal through UART.
I don't understand that. You are using your equipment regularly but I am not. You will need to provide a lot more detail.

Exactly, I have no idea why they appear.

Strictly speaking, there's no other way to test If the code is working on the transmiter. NRF module is connected directly to the power supply, not the arduino. Everything seems to be okay with that way.
I'm gonna try once more and then, I'll be replacing NRF module from the transmitter for the new one (short range, but without adapter, because it is impossible to fit one in), It's hard to solder out 8 pins at a time
Did I miss the bit where you installed Robins simple tx/rx software, as was requested earlier?
I have good news. It works, but... in what cost. Here's the story.
On the yesterday's night I wanted to solder out this old NRF module from the transmiter. I completely destroyed 2 pins (copper tracks) on the board, but managed to take it out.
Today I decited to connect another nrf adapter that I bought with wired, directly to the arduino pro mini. It sure looks messy, but I was hoping it would work.
Then I ran simple connection test from the Robin's tutorial and It sure was different then with the old NRF.
After that I ran simple TX RX (from the same tutorial) hoping that this would work. It surely did, I got message that the packets were send. With that I mind I uploaded my code for the transmiter and receiver. I did not work. So I used one line from the Robin's code:
const byte thisSlaveAddress[5] = {'R','x','A','A','A'};
Changed the address of the communication, and It worked as smooth as butter.
here's the
video1.
video2.
I'm not happy with the results, but hey... It's working.
Thanks you guys for helping me.
Good. You've proven that the 'electronical' parts are working, I guess you're not happy with the code/response to commands, whatever.
