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.

sudo node_modules/.bin/cylon-ble-info 8cde5263626e

peripheral with UUID 8cde5263626e found
  Local Name        = Bluetooth BP
