This device uses the shared HID protocol used by other
meters in the FreeStyle family. All messages that have been identified are

All commands supported by the shared protocol are supported by the device. Those that deviate from said protocol are here documented.
$result? command is used to dump the readings records from the device, and

The first field in the record specify the type of record; type 0 is a blood glucose reading.
Blood glucose record fields
type = "0"
month = 1*2DIGIT
day = 1*2DIGIT
year = 1*2DIGIT
hour = 1*2DIGIT
minute = 1*2DIGIT
value = 1*DIGIT
Unknown (but likely) whether this includes HI / LO constants.
The following commands appear to also be supported, but their meanings are not known:
