Bluetooth connectivity
Bluetooth connection of the WatchBP Analyzer
supports Microsoft Windows 10
Regarding the connectivity architecture design, we used
proprietary communication protocol to do data transfer
process. The specific communication protocol is assured
that the information (data) is correct. The program checks
ACK firstly. Afterward, the program compares the received
checksum with the sum of encoded raw data.
If the result is correct, the data is guaranteed during
transmission. In contrast, once the device gets wrong
communication command, it will not have any response.
It is a data encryption and decryption architecture. We
used proprietary encryption method to pack blood
pressure raw data. In other word, Blood Pressure Analyzer
need to use proprietary decryption method to unpack the
encrypted data to get blood
pressure raw data.
Pairing the device
Press and hold the Start/Stop button for 7 seconds, the
Bluetooth icon flashes and starts pairing mode. The unique 6-
digit device ID of the unit is displayed. Connect the device and
confirm pairing. The Bluetooth icon is displayed on the LCD
screen of the blood pressure monitor to show the presence of
Bluetooth connection.
See the instruction manual of WatchBP Analyzer for details
Please note the following:
Bluetooth is not active when the blood
pressure monitor device is recording data. The blood
pressure monitor device will not sound any alarm
with or without Bluetooth. The Bluetooth is used only
to transfer data from point A to point B.
Press and hold the Start/Stop button for 5 seconds to clear the
connection.
