KIT radio drotek

I have the kit radio drotek, sik based ( ) . They connect each other but no serial connection. I tried to reverse RX with TX but no problem was solved.
Any suggestion?


Are you using USB or UART?

Try to guess…!

After a day in lab, I found a solution…

Sorry I meant, “do you have the same problem with USB”? :slight_smile:

Usb is ok,the problem was with uart. Some FTDI I/O was high when the usb is not plugged. I found a solution changing a settings on FTDI chip.
