BLE Advertising - Appearance

[Jim Hewitt]

I'm working my way through BLE Advertising, a beginner's tutorial and getting a SDK error 4001 when trying to use

advdata.include_appearance = true;

Can anyone point me in the right direction as to resolving this?

After stepping through the debugger, I was able to pinpoint the error from

name_encode()

function which was returning NRF_ERROR_DATA_SIZE. The issue was that I had set

advdata.short_name_len = 6;

per the tutorial. When I changed it to 3 (as was shown later in the tutorial), it worked.
