Android Question Usb to Rs232 - which usb-rs232 converter did you use?

[amorosik]

I want to read the information arriving on the rs232 line on the B4A app
I'm trying to figure out which converter to buy, since I guess not all of them are perfectly compatible with the B4A code
Here are a few:

2 http://www.logilink.org/Products_Lo...Android.htm?seticlanguage=en&seticlanguage=en

4 https://www.elettroshop.com/convertitore-micro-usb-rs232-1-porta/

5 https://www.icintracom.biz/convertitore-adattatore-per-android-da-usb-otg-a-seriale.html

Have you tried any of these models?
For those who have tried any of these models above, could you confirm which one really works correctly with B4A code?
If you have used other models, could you tell us exactly make / model?
The final goal is to draw up a list of converters that are definitely 'visible' from the B4A code, including the software in addition to hardware compatib

You posted a message a little over a year ago but I found no response. I am trying to do the same thing you were trying. Were there any responses? If so what did people suggest? Any suggestions to flatten my learning curve? ty

I'm not sure if there is a way to use a USB to RS232 converter at all, but I personally used WIFI / TCP to RS232 and it works flawlessly. It is a more expensive option, but I think it is the only option for androidOS.

Have you tested with an RS232 converter?

Have you tested with an RS232 converter?

Yes, many times. It only requires that the converter uses one of the chips supported by one of the serial libraries and that you use an OTG cable to connect it.. Whether the final signal level is RS232 or TTL or whatever doesn't matter.

PS : I wrote the original USB and serial libraries for this very reason.

All right, I apologize for my lack of information. I used WIFI / TCP to RS232 because the situation required it and I can say that I am very satisfied with the work and capabilities of these converters. In any case, if I need it for a future project, I will be happy to try your libraries.
