I use this app, when I start use it, I just only can send char, I can't send hex to the device. how to set it char to hex? please help me , thank you very much
The uart in nRF-Toolbox is designed to send text(char). If you need to send hex, one option could be to convert the received characters to a hex value in the nRF5x application code.

For converting a string containing a hex number to int: see here.
It would be even easier just to send the number(the corresponding value the hex represent) as char directly, and then do the conversion from char to e.g. uint: see here.
I just need a APP which can send hex to the blue device. I download two app, one is nrf master, the other is nrf toolbox, but both the two app can only send char to device, there is no choice that can let me to make a choice to send hex to the blue device...
