I would make it
struct CharacteristicNames {
const char *uuid;
const char *name;
};

I would add { } at the end...

this should be static const char *get_char_name(const char *uuid)

... and change this loop into to:
const struct CharacteristicNames *c;
for (c = charNames; c->uuid; c++) {
...
}
This will keep convention used.

With that there is no need to initialize name to "" so this could be also
part of a patch.
If get_char_name() returned empty string instead of NULL if matching uuid is
not found we could append empty string as Name (as it is now), but not sure
what is better - append empty name or not append.
