Hi, am collecting the data from mpu6050 which has to be send through the bluetooth from ble peripheral to ble central..?

thank you sir , and one more doubt , i need to send the stirng from ble_app_uart code to the mobile phone through ble ,without typing anything over the serial monitor window ... what changes will i need to made in the uart_event_handle..??? , i don't know how to made , can anyone please say

@Reeshma yes of course, you can create your own service with your own characteristics to do that. Check BLE examples available in SDK so you will see how services/characteristics are built and make your accordingly. There are lots of examples to look at. nordic uart service is one of the good starting points.

Hello Reeshma

There is an example that is very close to what you're asking for. It is the Nordic UART service example.

The example uses two devices, one to act as central, and one as peripheral. It allows you to use a terminal like Putty to write to, and read from, each of the devices. The nRF5x uses UART to send and receive data to the interface MPU. Anything written to one device will be sent via BLE to the other, and the received data can be read in the terminal.

The code for the central device can be found in [SDK folder]\examples\ble_central\ble_app_uart_c

Documentation: infocenter.nordicsemi.com/index.jsp

The code for the peripheral device can be found in [SDK folder]\examples\ble_peripheral\ble_app_uart

Documentation: infocenter.nordicsemi.com/index.jsp

A UART example can also be found at [SDK]/examples/peripheral/uart
