USB-UART bridge¶
The USB-UART bridge acts as a serial adapter, exposing 2 UART pairs to a USB host as 2 CDC ACM devices.
Note
This sample has been enhanced by the Connectivity bridge application, and is planned to be removed in the future.
Requirements¶
The sample supports the following nRF52840-based device:
Hardware platforms |
PCA |
Board name |
Build target |
|---|---|---|---|
PCA20035 |
thingy91_nrf52840 |
|
The sample also requires a USB host which can communicate with CDC ACM devices, like a Windows or Linux PC.
Building and running¶
This sample can be found under samples/usb/usb_uart_bridge in the nRF Connect SDK folder structure.
See Building and programming a sample application for information about how to build and program the application.
Testing¶
After programming the sample to your board, test it by performing the following steps:
Connect the board to the host via a USB cable
Observe that the CDC ACM devices enumerate on the USB host (Typically COM ports on Windows, /dev/tty* on Linux)
Use a serial client on the USB host to communicate over the board’s UART pins
