The Client application should discover the Abeeway Primary service (UUID: 00008A45-1212-efde-1523-
785feabcd123). This service supports a writable and notifiable characteristic called Parameters configuration
characteristic with UUID: 00002740-1212-efde-1523-785feabcd123.
On every write command on its characteristic value, the tracker sends back the operation result through a
NOTIFICATION.
Before receiving a notification, the Client application must subscribe to the notification handler. This is done
by writing 0x01 to its related Client Characteristic Configuration Descriptor (cccd).
Once done, the Client application can receive such notifications.
The diagram below summarizes the operation described above.
Note:
1- To optimize the throughput during the configuration read or write commands, it is highly
recommended to use WRITE_CMD instead of WRITE_REQ.
4.3.6.2 Write parameters
Once the notifications have been enabled, the Client application can update a parameter by sending a write
command (WRITE_CMD).
