KIT radio drotek

Hi,
I have the kit radio drotek, sik based ( https://drotek.com/shop/fr/drotek-parts/795-kit-radio-telemetrie-433-915-mhz.html ) . They connect each other but no serial connection. I tried to reverse RX with TX but no problem was solved.
Any suggestion?

Hello,

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.
