Are you testing over Basic Rate? Looking quickly the code, the
function which extract the primary service UUID from the service
record doesn't convert the UUIDs to UUUID128 before converting to
string.
BTW: why are you checking again if the thermometer UUID is in the
list? The driver will only be probed if at least one UUID matches.

BR,
Claudio.
