sending hex values through ble_uart dongle

[bfernAnimate]

i am using the nrf52840 ble-uart  development kit examples (ble_app_uart_pca10056_s140), with an nrf52840 development tool board.  Connected to a device that only accepts hex data such as 0x7E, 0xFF, 0x06, 0x3F, 0xFE, 0xBC, through UART, i am trying to send hex from my phone to the device(smart fan), it's not responding. While debugging,  i connected the ble-uart tool to my computer via serial port and i sent the hex from the phone app to ble which then sends to the uart and i read from the console terminal. From the console output, i could only see unreadable values, instead of the hex that i sent. And sent back the hex data from the terminal, i could read it on my phone as i input them. 

how can i make it show the hex i sent through ble to the console terminal ?

any help would be welcomed.  Thank you!

So what "console terminal" are you using?

As Kenneth says, most terminals will, by default, interpret received data as ASCII-coded text.

You will have to study the documentation for your particular terminal to find out:

1. If it supports the display and/or entry of raw binary/hex data at all;
2. If it does, how to enable it.

'RealTerm', for example, is able to enter & display raw binary data: https://learn.sparkfun.com/tutorials/terminal-basics/real-term-windows

Thank you verry much for your answer, I am using Mac's terminal. 

I'll give it a try with realterm to havea better view of the result.
