To set up the MC13234 transceiver with the REM board and run the connectivity test demo, follow these steps:
1. Connect two 1323x-MRBs to their respective REM board headers.
2. Connect both boards to a PC using USB cables.
3. Power on the boards.
4. Configure the UART/USB virtual COM port on your PC to start a serial communication with the boards. Each board requires its own connection. You can use HyperTerminal from Windows for this.
5. Select the corresponding COM port and ensure the settings are configured as follows for each connection:
- Baud rate: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
6. Press OK and press the Reset button on each board.
7. You will see the Connectivity Test Demo menu.
8. Press "Enter" to see the available tests.
To conduct a Packet Error Rate (PER) test:
1. Once you are in the Connectivity Test Demo menu, press "2" on both terminals to select the PER test.
2. One board will be used as a receiver (Rx) and the other as the transmitter (Tx).
3. Receiver:
- Press "R" to set the board in Rx operation.
- Press the space bar to start listening to packets.
- The terminal should display the message "PER Test Rx Running."
4. Transmitter:
- Press "T" to ensure the board is in Tx operation.
- Start sending packets over the air (OTA) by selecting the number of packets to be sent.
5. Once the PER test is complete, a summary of received/sent packets will be displayed. You will be able to see if packets were not received due to poor signal or interference.
6. Press "Enter" to go back to the previous menu.
To conduct a Range test:
1. Once you are in the Connectivity Test Demo menu, press "3" on both terminals to select the Range test.
2. One board will be used as a receiver (Rx) and the other as the transmitter (Tx).
3. Receiver:
- Press "R" to set the board in Rx operation.
- Press the space bar to start listening to packets.
- The terminal should display the message "Range Test Rx Running."
4. Transmitter:
- Press "T" to ensure the board is in Tx operation.
- Press the space bar to start sending packets over the air.
- If Rx has been started, Tx will show a "Packet Dropped" message for each packet sent.
5. After packets are sent from the transmitter, the terminal will display the packets as being received with their respective Link Quality Indicator (LQI) value. The stronger the signal, the closer the LQI value will be to 255.
6. Press the space bar to stop Tx/Rx.
7. Press "Enter" to return to the previous menu.
