Connecting to Thingy:91

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

UART_1

1000000

Using nRF Connect Serial Terminal

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