Hello,

Did you check the source code for nRF Toolbox app?

This site contains a link to the github where the source code is located.

In nRF Toolbox, there is a module called "UART". This you can use to communicate with an nRF programmed with the ble_app_uart example. You can use this to send data back and forth.

Please see the example's test description:

Best regards,

Edvin
