Only hex format supported by nRF Connect UART over BLE

[liuxyu]

I am using nRF Connect with nRF52 and need to use UART over BLE to send command to the device but I find that you can only use hexadecimal input and get hexadecimal output. So it is not very convenient for you need to transfer between text and hexadecimal representation. I cannot find any settings or configurations in the software. Does anyone know how to figure it?

No you don't. The UART service just sends bytes, you don't need to transfer between anything and anything. If you have a text string, that's just bytes, send it one byte at a time.

'hexadecimal input and hexadecimal output' doesn't mean anything. That's just the representation of the data, underneath, it's a number between 0 and 255.

I know the hexadecimal is just the representation of data, but I need to use UART over BLE to test the device, can I find some alternative for nRF Connect. I can only find a UART over BLE app in Android. But I need to do it on PC.

Hi liuxyu,

Thank you for the feedback. I have contacted the developers of nRF-Connect for PC, and we will hopefully add support for this functionality in an upcoming release. The nRF-Connect for smartphone have this functionality, so it should also be added for the PC-version of nRF-Connect.

Thank you very much!
