what should be used to send data on Bluetooth?

[vohra alihussain]

hello, 

I am newer to nrf. I am using nrf52832 development kit and using soft device 5.0.

I have confusion with two function with nrf_log_info and printf?

which should be used to send data on Bluetooth?

[Turbo J]

Neither function should be used.

then what should use?

Hi Vohra,

To send data over BLE you can use BLE services.

One example is to use the Nordic UART service, which is used in the "ble_app_uart" example.

It could be a good idea to use that as reference. 

Please take a look at the BLE tutorials, especially the theory behind it to get an understanding how communication over BLE works.

Do you have any experience with 'C' programming?

It is usually easier to learn the language on a PC (or similar) - away from the added complications of embedded microcontrollers.

Here are some 'C' learning & reference materials:

Do you have any experience with any other microcontroller(s)?

Have you looked at the documentation?

Nordic UART Service overall:

The ble_nus_data_send() function in particular:
