I have an RLM100 UHF RFID module. I searched a lot, but I didn't found anything useful that explain how I can use this modules. I mean the only thing that I understand so far it that this modules use UART protocol to communicate with the MCU, but I need a list of commands that it support, right? 

 

May I ask you to share me in your experiences with these kind of modules? Does they have an standard list of commands or something, or I must gain a more complete data sheet? If so, where I can find it? Why it is not available on the Internet? 

 

All I want to do is reading a tag and storing its number(?) in the MCU EEPROM.

 

Thanks in advance.

Why ask such a question here - especially when you've asked the same on Stack Exchange? Why not just contact the manufacturer? It would help if you speak Chinese. You might want to look elsewhere for a module with support.

A key requirement when choosing the components for any system is to ensure that they have adequate documentation.

 

It's not as if there's a shortage of RFID module suppliers ...

So you've already had that advice in your cross-post: http://electronics.stackexchange...

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

I asked this question on 14 different communities in Persian and English. Why? Because I think these comunities have different members and different experts inside. Am I wrong?
I have sent some emails to the manufacturers technical support group also, but they didn't answered yet.
Unfortunately I don't know Chinies language (It seems that I must learn it finally;) ), by the way I tried to call them, but the number that is in the website, seems wrong.
And I didn't choose this component! I am forced to use it. :)

It is not polite to ask the same question on multiple forums - especially without making clear that you've done so!

 

I think these communities have different members

Exactly - so you are very likely to be wasting people's time as they give the same answer without knowing that it's already been given on the other forum(s).

 

But you should learn something from the fact that you get the same answer independently on different forums...

 

I am forced to use it.

 

So who "forces" you to use it?

 

If they insist on you using it, why don't you insist on them getting the documentation for you?

 

Or, at least, insist that they arrange for a competent Chinese translator for you...

Yes, you are right, I am just understand it and I won't repeat it. Thank you.

In the other side, I was thought that maybe one person on these forums have some experience with this component.

You are completely right.
