1 How to use the BLE Scanner app

Follow the procedure below to evaluate the functionality of the AEK-COM-BLEV1 board functionality.

Step 1. Use the SPC5-UDESTK-SW software to download STSW-AEKBLE onto the AEK-MCU-C4MLIT1microcontroller (SPC58EC80E5)

Step 2. Use the wiring scheme in the following table to connect the AEK-MCU-C4MLI1T and AEK-COM-BLEV1 evaluation boards.

Table 1. AEK-COM-BLEV1 and AEK-MCU-C4MLIT1 connection

Pin 2 [GND] A1 [GND]

Pin 3 [+3V] C37 [3.3V]

Pin 4 [RXD] B21 [TXD]

Pin 5 [TXD] D17 [RXD]

Pin 6 [RESETN] C17 [RESET]

Step 3. Install the BLE Scanner app on your mobile phone
