I want to send a information through BLE. I can handle the uart example but want to use custom service

[Nor_Kim]

I've used PCA10040 sdk15.0 example ble_peripheral ble_app_uart

I can handle it through terminal.

If I insert strings through terminal, App can receive.

But, I want to send a message directly PCA10040 to App.

for example, temperature or LED state .. something like this.

Before the sdk 14.0 People use

//

memset(PrintBuffer,0x00,sizeof(PrintBuffer));

power_manage();

//

I think it is changed when it goes to 15.0 to

idle_state_handle();

I want to send a message through BLE directly nrf to App. Help me.

Not clear what you mean - the  Nordic UART example does exactly that!

Look at the  Nordic UART example code. See how the received message from the UART (ie, from you terminal) gets sent to the NUS API. Do the same with your "custom" data.

The Nordic UART Service - just like a real UART - neither knows nor cares where the data came from, or what it represents.

Assuming that you don't want to expand the UART example with a defined serial protocol e.g. string message "LED 1 ON", and the handling that goes with it then I would suggest that you look closely at the blinky example and adapt the button service to your needs. The button service supports notification events whilst the LED state can be polled by the app. (read) as well as written to.

Not through the terminal. I want to let the board acts like this.

That is, instead of the data arriving via the UART, you supply it direct to the NUS API.

You just use the UART example code as an example - or illustration - of how to do that!

Thank you, I'll try to do that.
