hey guys I know this is a long shot. I believe that my RF (433Mhz) receiver has gone bad, and I have some new codes that I need to learn for some RGB led strip lights using RF.

I thought at first that I got a remote/controller that isn't using 433Mhz, however when I test a remote that I already learned the codes from, it doesn't detect any RF signals. Occasionally it will show phantom codes, but nothing in the right range to the original RF codes from my projector screen remote

Example:
projector screen remote (good code)

Code: [Select]

1103,104,36ABABBABAABB90,124BAB25ABAABABBAABBAABBAAB45CBABABAABF
phantom codes (bad code)

Code: [Select]

153,60,11B36,56B18,13B16G32,30,24,21BGBBBGKG51BHKCBBG
If the RF Receiver (433Mhz) has gone bad, will either of these work for the replacement?

Ebay 433MHz Superheterodyne
 

Thank you

Hi PegLeg,
the phantom code looks really bad - did you checked the BEAM plug-in RF settings if there is something wrong with the parameter?
If the Chip is damaged, the first one of your Amazon link is the best choice.


One other thing - are you sure you have only insert the 433MHz RF receiver in your BEAM? You can use only one receiver in the BEAM for learning RF codes (433MHz or 315MHz). So if you have both receiver installed, remove the 315MHz Chip first before start learning a code.

Hey kalle, yeah I double checked that I was using the same settings as James does in his tutorial video. I tried adjusting the noise setting to see if that helped and it helped to block the phantom codes but still couldn't read the remote code.

I swapped my RF receiver chips incase I had the wrong one installed and still didn't see any codes.

Thank you! I'll get the one from Amazon ordered, and let you know how it goes.

[Kalle]

Try first a new chip, if this doesn't help, let me know and I can assemble you a complete new PCB Board with all components.

Best wishes,
Kalle

[jitterjames]

I did not know those chips could go bad but they are pretty cheap so trying a new one is probably the easiest place to start.

You should also try to remove the chip, check that the contacts are clean and that the antenna is secure and put it back in.

Make sure when learning codes to avoid other RF signals if possible and put your remote close to the receiving chip. There can also be some technique involved in holding down the remote button for long enough. Varies by remote.

Good luck and let us know what happens.

I got the new 433mhz chip set in yesterday and got the anttenas attatched. and it solved the problem. 

I'm working on learning the codes for my RF Led strip Lights, the codes are extreamly long, the only working codes are the initial raw codes, and they cause the Beam to restart and VC to freeze for around 20 seconds after sending them.

I've tried adjusting settings to no avail.

current settings:
Lock Min: 100
Lock Max: 1202 (lowest it can be set or I don't get any codes)
Noise: 10
Equal: 2

I've tried adjusting all of the above settings, but I see the same results.

Raw Code for "power on" that works but causes the Beam to restart.

do you guys have any tips on how to shorten these codes so they don't cause the beam to restart and vc to freeze, other than manully editing them?

update: I created a VC Command to Shorten the codes. I was able to shorten all the codes so they don't cause the beeam to restart or cause VC to freeze.

thank you!

Hi PegLeg,
nice to hear that your problem is solved.
You can also send the compressed code instead of the raw code which is displayed in the BEAM plugin.

example code: /sendRFraw?code=1130,39,104ABABABABABABABABABABBAABABABABABABABBAABBAABABA


or an other option is to use the BEAM WebUI for learning a code (if it possible) and maybe you have a code that looks like: /sendRF?code=4116&bits=24&n=1

[jitterjames]

You may only need up to the first larger number, possibly also setting n>1

eg:

Code: [Select]

{M:IP.Beam 2.0}/sendRFraw?code=102,134,32,128,36,124,40,122,41,121,42,40,121,42,121,42,120,122,41,41,121,122,42,41,121,121,42,121,43,40,122,41,121,41,121,42,120,42,120,122,41,41,121,42,120,42,1201

Kalle, sorry I forgot to respond to yours when I got back home. the raw codes that worked never produced anything on the bottom half of the screen like your showing in the picture, so it took me a little bit to spot when a raw code was good or not just had to look for the lenth and starting numbers.

After some testing I found that if I cut the raw code down to 96 integer groupings then the commands would work and not freeze VC and restart the beam

          1     2   3    4   5
         102,134,32,128,36

from there I made a command in VC so I could input the raw code and the remote button name and have it create a map table with the button names and code, along with testing the new raw code. from there it was fairly easy, all I had to do was repeat that 32 times for all the buttons I wanted to learn. 

only four buttons where difficult to figure out (dim,brighter, faster, slower) but after some testing I relized that they need to be repeated multiple times in order to see a difference so I just added &n=9 to the end of the raw codes and the problem with those buttons were solved.


Jitterjames, I tested the raw code you posted and I also tried your code by adding &n=2 to the end of your command but still no luck, from what I can tell it seems that anything less than 96 integer groupings the codes would not work. however after looking at the raw code with your input I did find that the code repeats twice minus the big number.

Now that makes me curious - I have a lot of 433MHz remotes and none of them produce such a start frequency. What I mean, your RF code starts with a relatively small sequence of numbers (initial code: 102,134,32,128,36,124,40,122,41, ...), which I have never seen before, no matter from which RF remote control - the initial code always starts with a large number.


I am in the lucky position to test your working code with two BEAM's and the BEAM Plugin (one BEAM transmits, one receives) and have the following result which you could try out.

/sendRFraw?code=1019,69,105,54B129,36DEDEDEE120EFEFDEEFDEEDDEDEEDEFEFCFEFDEEF45BDEDEDEDEFEB248,24DFCEDFEEDFEFEFEFEFEFEFEFEFEFEFEEFEFEFEFE

This is a part of your original code, which i have shortened:
/sendRFraw?code=1201,55,108,52,111,128,36,125,38,124,39,123,40,122,41,41,122,41,121,42,120,122,41,41,121,121,42,41,121,122,42,121,43,40,122,41,121,41,121,42,120,42,120,122,41,41,121,42,120,42,


In the Beam plugin there is the possibility to adjust the noise - try higher values, this will filter the sequences a bit or lower values to see more sequences but a lot of trash.
What surprises me is that you don't get anything in the BEAM plugin under "Compressed Code" when you try to learn the remote control with the BEAM.

no compressed code.

Note: I would see some occasional compressed codes but when they showed up none of them worked, and neither did the raw code. So as I worked through the remote buttons if I saw compressed codes, the raw code didn't look like other codes that worked, so I wouldn't test it.

I only have one other remote that uses 433mhz (projector screen), and that remote never generated any compressed codes origianly. when I test it now, the raw code is much longer and causes VC to freeze short tearm and the beam to restart, but the raw code does work.

after looking over the code, there are six codes generated, all of them work, the first one is different and the last five are identical. with this remote the projector screen will beap when the button is pressed so I only press the button until I hear the beap which is a quick press of the button.

this remote does start with a higher number like your mentioned in your post.

these are the remotes that I'm testing with

Amazon: SUPERNIGHT RGB Light Strip Remote Controller, RF Remote
Amazon: Projector Screen

the LED RF Remote doesn't say if it is 433mhz or 315mhz, it was a black Friday sale $6.33 USD so I risked it, when the beam couldn't read the remote origianally, I ordered a remote that said it was 433mhz however even with the new RF receiver that remote never produced any codes with the beam so I returned it.

I'm sorry I know that that is a lot of information above, but I wanted to make sure you knew what I have tried and what the results were.

Thanks for all the info.


If the second code was work for you, it is easy to shorten all you codes without an math or regec or what ever.
The only thing you have to do - take a look where is the large number is and cut it out to the last number before the next similar large number starts (include thecomma at the end).


example:


123,41,121,41,120,122,41,41,120,122,41,41,120,122,41,121,41,41,121,42,120,42,120,43,119,43,120,123,40,42,120,43,120,42,1201,57,106,53,110,128,36,125,38,124,39,123,40,122,41,41,121,42,120,43,119,123,40,42,120,122,41,42,120,122,41,121,42,41,121,42,120,42,120,42,120,43,119,123,40,42,120,42,120,42,1201,56,107,53,110,128,36,125,38,124,39,123,40,122,41,41,121,42,120,42,120,122,41,42,120,122,41,41,120,122,41,121,42,41,121,41,121,42,120,42,120,42,120,122,41,42,120,42,121,42,1201,56,107,52,111,128,36,125,38,124,39,122,40,122,41,41,121,42,120,42,120,122,41,41,120,122,41,41,121,122,41,121,42,40,121,41,121,42,120,42,120,42,120,122,41,41,120,42,121,42,1201,56,107,52,111,128,36,125,38,124,39,123,40,122,41,41,121,42,120,42,120,122,41,42,120,122,41,41,121,121,41,121,42,41,121,41,121,42,120,42,120,42,120,122,41,41,121,42,120,42,1201,56,107,52,111,128,36,125,38,124,39,122,40,122,41,41,121,42,120,42,120,122,41,41,121,122,41,41,121,121,41,121,42,40,121,41,121,42,121,42,120,42,120,122,41,41,121,42,121,42,1201,56,107,52,111,128,36,125,38,124,39,123,40,122,41,41,


This is your posted raw code and you can see the correct sequence ist starting at green and repeatedly continuous - the red marked is the code is not needed.

normally noise should be set lower (maybe 5) and increasing the "Equal +/-" to about 10 is going to help your compressed codes.  You see your values of 38, 41, 40, 42.  Those are probably all the same duration and the Equal +/- will allow VC to see that they are all the same and change them all to the average of their values.  So they will all be set to something like 40, and then replaced with a letter.

What version of VC are you using Pegleg?
