4.3.1.4 Bluetooth Low Energy Test Mode

Perform the following steps for the demonstration of the Bluetooth Low Energy Test mode:

1. For the Bluetooth Low Energy Test mode, the sample must contain the following connection:
   • HCI_TXD: The PA5 pin on the GPIO header (J702) is the same as the PA5 pin of the PIC32WM-BZ6204UE Module.
   • HCI_RXD: The PA6 pin on the GPIO header (J702) is the same as the PA6 pin of the PIC32WM-BZ6204UE Module.
   • VDD: Connect with external power supply.
   • Ground.

   

   Note: For more details, refer to the GPIO Header (J701 and J702) section of the EV31U42A PIC32-BZ6 Curiosity Board User's Guide (DS00006006).

2. Use the USB-to-UART serial converter to make the connection between the sample and PC by connecting the HCI_TXD, HCI_RXD and ground with the converter.
3. Power the sample with 3.3V supply.
4. Select the respective COM PORT (the COM port with the converter) in MCHPRT3.
5. In the RF BT tab, perform the following steps:
   1. From the “RF mode” drop-down list, select Test Mode.
6. Click START to enter the Bluetooth test mode, then click Disconnect in the GUI. Disconnect the UART interface from the DUT while keeping the power supply, then connect it with the Bluetooth tester.
