There are two ways to specify the length (in bytes) of a characteristic.
One way is to use the attribute inside the element. length="..." <value>
Alternatively you can simply include the data inside the element, which for example must be <value>
done with constant data. Using this will override the length defined with length="".
Example:
<characteristic uuid="2a00">
<properties read="true" const="true" />
<value>Device name</value>
</characteristic>
When you specify , bgbuild compiler will interpret the data inside as hexadecimal, which type="hex"
affects the interpreted length.
Example:
<value type="hex">0001</value> is two bytes
<value type="utf-8">0001</value> is four bytes.
