Pairing is required to read the following characteristics.

• Blood pressure measurement, 2A35

Peripheral : Omron HEM-7600T (Omron Evolv)

Step:

1. Pairing begins when this characteristic is read ( setNotifyValue ).
2. Pairing will begin and can be completed manually.
   Once pairing is complete, the peripheral will disconnect.
3. You can reconnect and read ( setNotifyValue ) this characteristic again to get the measurement.

• Note: Once a measurement has been read, it cannot be read again.
  If you really want to get measurements you need to access the EEPROM.
  Please read https://github.com/userx14/omblepy for more details.

I'll write this down for anyone coming later.
