My First EZ-BLE PRoC Module Design
This section provides you with the step-by-step process for building a simple design with EZ-BLE PRoC Module using PSoC
Creator. We will use a previous example project completed for the PRoC BLE device and reconfigure it to work with the EZ-
BLE PRoC Module.
About the Design
This design demonstrates the ―Find Me‖ profile operation using the BLE Component in PSoC Creator. The example uses the
"Find Me" target profile and operates as a BLE server that can communicate to a BLE Client (Smart Phone or PC). It can
operate with another device that uses the "Find Me" locator profile and acts as a BLE client. The "Find Me" target profile uses
an instance of the "Immediate Alert Service" to display alerts when the locater device sends them.
When in discovery mode, the
‗Find Me‘ Target remains visible for BLE clients. The device switches to Deep-Sleep mode
between BLE connection intervals.
For this design, the BLE configuration in
Table 4
is used.

Connection Parameters
Connection interval = 7.5 ms
Slave latency = 0

This design uses GPIOs for three LEDs to indicate different states, a button switch for wake-up from Deep Sleep, and a BLE
subsystem to enable the
‗Find Me‘ profile through the BLE protocol. The schematic for the design from PSoC Creator is shown
in Figure 22.
