In your post from Wed Sep 27, 2023 7:13 pm it shows COM8 for the Arduino Uno in the IDE.
In your post from Thu Sep 28, 2023 5:18 pm you refer back that it is COM8 showing the IDE for the M6E, but that is for the Arduino Uno.
----it’s both connected to FTDI<—>Nano, I am just showing that I am detecting COM8 in IDE, but not in the reader…(Arduino UNO with USB cable, COM6)
if you have an FTDI for the Nano, why don’t you use that with the Raspberry PI as that will give you /dev/ttyUSB0 and maybe works?
— I will try and get back to you…
Thoughts:
Can you select voltage on your FTDI (some are set for 3v3 and that will not work)
— I have both option 5V and 3.3V
Is the power light on ?
– Yes power light is on
Do you have pictures of the M6E Nano connected to your PC ?
____I will attach in next post
This is the picture of output…FTDI to Pi3…ttyUSB0…(Time our error)
try USB1,2,3…(File not found directory error)
these are the pictures connected to Pi3 and my laptop using FTDI.
While Connected to the PC. it’s showing COM8 connected in the Control panel
Is there any debug message OR Firmware update OR any other things we can check ?
This is taking longer and my sponsors asking answers from me… I hope you understand
Thank you

thanks.
Try on the raspberryPI, connect the Nano to the FTDI
go to mercury-API-folder/c/src/api
./readasync tmr:///dev/ttyUSB0 --ant 1
it should connect without an error
If that does not work, let’s make sure the FTDI is working
remove the Nano from the FTDI
connect the TX and RX on the FTDI together
with a serial console like putty ( else install putty first : sudo apt-get install putty -y)
start putty from command line , select serial, select /dev/ttyUSB0, select open
any character you type you should see back on the screen.
if it does, remove the TX RX link and now the characters will not be shown.
If all the later works, all I can think of is that your Nano software is broken and does not work correctly. it should be replaced
yes as you mentioned I try raspberryPI, connect the Nano to the FTDI
go to mercury-API-folder/c/src/api
./readasync tmr:///dev/ttyUSB0 --ant 1…and you can see error on the screenshot mentioned below.
Then I perform this
let’s make sure the FTDI is working
remove the Nano from the FTDI
connect the TX and RX on the FTDI together
with a serial console like putty ( else install putty first : sudo apt-get install putty -y)
start putty from command line , select serial, select /dev/ttyUSB0, select open
any character you type you should see back on the screen.
Working… You can see result
if it does, remove the TX RX link and now the characters will not be shown.
not typing and reflecting anything…see the attached picture

all I can think of is that the M6E nano is not working. Contact the seller for a replacement.
Hello
Now I have received the replacement and with arduino UNO…constant read program work if tag is just on top of that.
While try to running with raspberry pi 3, I am getting Time out error…
please check the attached picture.
Thank you

How do you connect to the RaspberryPI (looks you use the FTDI to USB). ?
How did you connect the wires? Any impact of the UART-switch?
Did you tried any of the previous test proposal?

- yes using FTDI
How did you connect the wires? Any impact of the UART-switch?
- HW-UART, connected to serial section of Nano board… right next ti lithiam-ion connector
Did you tried any of the previous test proposal?
**- Yes i try ans see the result in attached picture**

Please : Don’t try to put many pictures in one picture… it is impossible to read.
Putty seems to indicate it can not open /dev/ttyUSB0. Can you confirm why would that be?
Yes No many thigns in one picture
I restart thr pi3 now it’s good, putty system is working.
but when try to read I get the same error of time out

We at least now know the M6E is working when connected to the Arduino.
The ONLY last new idea that comes to mind is wiring : e.g. RX and TX are switched. If not look back at all the advice/tests given before as I can’t think of others.
No, I checked with wiring. It looks good.
I try in Windows, Universal Reader…It’s showing the same…No serial reader detected…
See the attached picture.
No other device is connected…Just my USB mouse and Headset.
Do you want additional information? I just follow the steps mentioned in the Hookup guide.
Can you guys please confirm why this is bothering…
Thanks

can you try a different USb port or on another PC ?
can you get hold or borrow another FTDI for test ?
As stated earlier I am out of ideas to help more.
I tried with another USB port and PC as well, the same result.
I tried another FTDI, it’s the same not working
I found this YouTube video (https://www.youtube.com/watch?v=CAujiS_aqt8 ), using SparkFun RFID reader and the same FTDI (https://www.silabs.com/developers/usb-t … cp-drivers ) as I am using. The results are reflecting…
Thank you

Just ONE more thought as I bothers me why it would not work and (nearly) everywhere else … I have mentioned earlier. Some FTDI can be set to 3v3 or 5V VCC. Is yours set to 5V ?
I think it’s set to 5V because I uploaded the code to Arduino UNO without any external power supply.
Still, we can revise the Wiring. as I missing any wiring. ???
Do you think that the URA application is not able to find COMS…there might be a path location, sketch location something like in the Arduino IDE we are providing sketchbook location…???
What about Raspberry Pi 3, I am still getting Time out error…
