ETURSON Posted May 28, 2018 Report Share Posted May 28, 2018 I have a LoPy device as shown in the link below: https://pycom.io/hardware/lopy-specs/ I also have the Unitronics US5-B10-TR22. I am trying to connect US5-B10-TR22 to LoPy via Silicon Labs CP210X USB to UART Bridge. I enabled the Panel USB Port as TX/RX from Physical-Controller USB Port. Then I used Com TX to send data to LoPy as shown below and I also attached the simple code I wrote. But I never succeeded sending any data. The Com module gave me error code -1, which is general com error. I never programmed Unistream before and I am just learning. Can I communicate to LoPy via Panel USB Port? If yes, how can I do so?
