Connecting to Thingy:91

You can connect to Thingy:91 wirelessly (using the nRF Toolbox app) or over a serial connection (using the Serial Terminal app, the Cellular Monitor app, or a serial terminal).

Using nRF Toolbox

To connect to your Thingy:91 wirelessly, you need to meet the following prerequisites:

  • The Connectivity bridge installed on your Thingy:91.

  • The Nordic UART Service (NUS) enabled.

    Note

    By default, the Bluetooth LE interface is off, as the connection is not encrypted or authenticated. To turn it on at runtime, set the appropriate option in the Config.txt file located on the USB Mass storage Device.

Using a serial terminal

If you prefer to use a standard serial terminal, you need to specify the baud rate manually.

Thingy:91 uses the following UART baud rate configuration:

UART Interface

Baud Rate

UART_0

115200 (default)

UART_1

1000000

Using the Serial Terminal app

You can use the Serial Terminal app to get debug output and send AT commands to the Thingy:91. In the case of the Serial Terminal or the Cellular Monitor apps, the baud rate for the communication is set automatically.
