Data in binary format over UART

[Ars Morozov]

Hello. How can I send binary data (in order to not convert it to ASCII string) over UART?

I have sensor data (obtained over BLE). Every measurement is 13 bytes, sample frequency is 2kHz. I need to save it on PC. I decide to work over UART. So if I convert it in normal readable data with float point, then convert to string and then send over UART with 2kHz frequency it will be to fast for max possible uart speed of my nrf52832.
Thats way I want to send it in binary format. How can I do it?
Thanks in advance

Hi,

You might want to consider using Segger RTT if the UART speed is too low. You can then also use printf() to print float values. You might have to do some changes to your IDE to get it to work. Do a search for "your IDE" + "float" on DevZone and you will get a lot of answers.

Thanks for reply, but could you give little bit more information about Segger RTT, which interface it use? How can I get data on PC, if I use Segger RTT? Maybe you have some examples with RTT? 
You talk about using NRF Logger as data transmitter from board?

I use segger embedded studio. Float point support (you talk about it?) is on.
