How to write sensor values into Tx characteristic of NUS service?

[Hrushi]

Hello All,

I want to write the peripheral code which will send sensor reading to central.

For that I started looking into the Uart_Nus peripheral code from SDK. I tried to write some hard coded values using ble_nus_send_string() function but it didn't work.

Can you please guide me how I can write the sensor readings into TX characteristics and notify it to server?

The ble_app_uart example is a good starting point yes. So what happened? Did ble_nus_send_string() return an error? Or 0x00000000 (NRF_SUCCESS)?
