How to send data from Tx to Rx (NRF52840)

You can just flash those hex-files to your development kits and test using Putty.

ble_app_uart_c_pca10056_s140 is for the central device and ble_app_uart_pca10056_s140 is for the peripheral. The hex file includes both the application and the softdevice.

You can program the hex files to the development kits using the nRF Connect - Programmer application.

Hi, how do I include those hex file into Tx part ? Is changing main function required? If so, can you share the code? Thanks in advance. 🙂

I tested the exact same setup, and everything works as expected.

Could you test these pre-compiled hex files and check if the result is the same?

Thanks.

I'll set up the example on my end and see if I face the same issue as you.

Let me get back to you with more information.

Thanks!

The settings looks fine.

Did you use the UART examples like I suggested?

Hi, this is putty setting for both Tx and Rx except the COM port number :)

That is good!

Maybe you could add a screenshot of the settings you use in Putty?

Hi, after trying the links you provided, I managed to send data over BLE but cannot see the letter but only weird tiny dots on putty of the peripheral whenever I type something on the central putty. Also I cannot see the typed number on putty of the central, what seems to be a problem? Thanks in advance.

Hi again!

Every test step is described in the example documentation.

Peripheral
Central

On which step are you stuck? You have downloaded the firmware to both boards, but can not send data?

Hi , yes i tested an example you sent plus i set up two nrf board connected to two computers each: set one as central_uart example the other peripheral_uart example in ses environment. The problem is from now, i want to test if central nrf could send one bit to peripheral nrf but i dont know how to.(If one bit transmission is working then i can send multiple millions of binary data which can correspond to audio data). I tried to send 1 for example by typing on debug terminal in ses but no response in peripheral part of computer ses terminal.(I dont know if this is a right way to test anyway). Just in case I also downloaded putty to test serial communication but it doesnt read my keyboard. How can i proceed now? Thanks in advance.

Thanks.

Will do my best to get you started with one of the examples.

Did you have a chance to test the UART example that I linked to in my previous response?

Hi thanks for answering.
I am working with SES and I guess I downloaded 17.0.1 SDK if i remember correctly. Also I want to send data using BLE. Thanks in advance.

Hi!

I understand. I'll do my best to help you get started.

First of all, may I ask which version of the SDK you have been working with? Are you working with NCS or the nRF5 SDK?

[quote user=""]I followed the basic examples (blinky, uart) but have no idea how to proceed next to send data from tx to rx.[/quote]

Do you want to send data via serial connection, or using BLE?

The UART example allows you to send data from one device to another. You can look at the documentation for the example on how to test this.
