Connecting Unistream to LoPy via Panel USB Port

Recommended Posts

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?

Hello,

Please make sure that you are using USB to Serial based on  "PL23203 USB to Serial/UART Bridge Controller".

You'll have to use it to be able communicating between the LoPy and UniStream  controller.
