I loaded the ble_data_transmission example for Hexiwear and I can see the serial port showing that it is running fine.
However, when I open my phone or look at my computer’s bluetooth, I cannot discover the Hexiwear at all.
I see in the comments that
"The original Hexiwear default application binary file must be pre-loaded inside the kw40z
But when I click the link, it is not working.
