How to send data from pca1001 to BLE UART Android App?

[Annim]

Hello,

I was working over nordic dev board and found the uart template. but in that, only "data_receive_handler" is mentioned. i want to send data from my dev board to android uart app.

• Is there any handler i should write? what and how?
• Is there any api shall be called to achieve this?
• In the documentation i found the same code piece with some detailed explanation. But not explanation about sending data (about TxData).

You can send data to the nRF UART app by using ble_nus_send_string(...). The function is used in UART0_IRQHandler().

It relays the data received over UART to the nRF UART app.
