I got a Bluetooth blood pressure monitor U80IH and trying to understand how I can read data from this device using noble npm module using GATT interface.
I run scan
and info
commands using cylon-ble
and got this results....
Seller/manufacturer didn't provided GATT specification for this device.
Trying to see if someone can reverse engineer and find the way to start measuring process and read data.
