Hi,

What do you mean by "it doesn't give me options about data type...." ? Isn't it give you more option when you click on "Byte Arr" drop down menu ? What kind of data type you are looking for ?

Hi,

You can have that option as in "desired_output.jpg" if you don't use NUS service/characteristic UUID. When you use NUS UUID our nRFConnect app automatically detect the data type and don't give you option to do other type.

So if you modify the NUS UUID (NUS_BASE_UUID) to your own UUID (anything you random generate, checkout "UUID generator") can be used. Then the nRFConnect won't detect it as UART service and you should have all the options.
