configuration descriptor is configured for indications and a blood pressure measurement is available, this
characteristic is indicated while in a connection.
• The blood pressure measurement characteristic is used to send blood pressure measurements
• The intermediate cuff pressure characteristic is used to send current cuff pressure values to a device to display,
while the measurement is in progress
• The blood pressure feature characteristic is used to describe the supported features of the blood pressure
sensor
The ATBTLC1000-MR/ZR together with the host MCU simulates a blood pressure sensor (GATT server role) and
sends simulated values to the blood pressure monitor (Microchip SmartConnect mobile application).

Find Me Profile Application
The Find Me Profile (FMP) application is used to define the device to create an alert signal behavior when a button is
pressed on one device to cause an alerting signal on a peer device.
Find Me Target
The FMP defines the behavior when a button is pressed on a device to cause an immediate alert on a peer device.
This can be used to allow users to find devices that have been misplaced.
The Find Me Target application, which is the GATT server, holds the alert level characteristics and waits for the Find
Me locators alert and performs the following alert level characteristic:
• When the Find Me locator device wishes to cause an alert on the Find Me Target device, it writes the specific
alert level (High, Mild and No alert) in the alert level characteristic.

Phone Alert Status Profile Application
The Phone Alert Status (PAS) profile is used to obtain the phone alert status exposed by the phone alert status
service on a mobile phone. The alert status and ringer setting information of a mobile phone can be received and
modified by the phone alert status service. The device can also use this profile to configure the ringer status on the
mobile phone.
Phone Alert Status Notifications
This profile defines two roles:
• Phone alert server – device that originates the alerts
• Phone alert client – device that receives the alerts and alerts the user
The phone alert client (a GATT client) configuration is implemented on the ATBTLC1000-MR/ZR along with a few
other supported hardware platforms and IDEs (see
). The example application utilizes the SW0 button on
the supported hardware platform to demonstrate the notification use-cases. A BLE compatible Android device that
contains the Microchip SmartConnect mobile application provides the phone alert server functionality in this example.
On the application, once the service is discovered and the user can click on the PAS service to enable the
notifications.
1.
After connecting with the mobile phone, press the SW0 button once to set the PAS server to “Silent” mode.
2.
In the second SW0 button press, the device is set to “Mute” mode.
3.
In the third SW0 button press, the device is returns to “Normal” mode.
4.
In the fourth SW0 button press, a “Read Characteristic” request is issued that reads the characteristics of
“Alert Status”, “Ringer Settings”, and “Ringer Control Point”.
Note:
The PAS profile application is not supported in iOS devices. This example works only with BLE compatible
Android devices that contain the Microchip SmartConnect mobile application.

Alert Notification Profile Application
The Alert Notification Profile allows a device to obtain information from a mobile phone about incoming calls, missed
calls, and SMS/MMS messages. The information includes the caller ID for an incoming call or the sender ID for an
