Note: Understand that the COM connection is established as soon as you select the

COM port and click on

OK. If you remove the USB cable without closing the terminal,

the COM connection breaks but is not fully closed. And if you plug the cable back

in the USB, the COM connection does not establish again. Therefore, you will see

that the terminal does not respond.

Therefore, always close the terminal before

removing the USB cable and open the terminal only after you have plugged

back in the USB cable. Connect the RESET pins of both boards and use middle

reset button on the KL43Z board to reset. Unplugging and replugging the USB is not

the preferred way to reset the boards.

7. After you Press the reset button on the KL43Z, a menu as shown in Figure 15 will

appear, indicating that the KL43Z board is properly set up.

8. Type

1 and press Enter to send wakeup command over SPI. By default, after power-

on reset, the device goes in deep sleep or POWEROFF2 power-saving mode.

Therefore, the wakeup command always has to be sent first after any kind of

board reset.

9. Type

8 and press Enter to send a Get info command. This command will display the

ID and the PAC value of the device. Even if these values are zero, if you see SPI TX

buffer and SPI RX buffer bytes, SPI bidirectional communication is working.

10.The next command depends on the region you would like to test, namely RCZ1,

RCZ2, RCZ3 or RCZ4. Choose between 0x15, 0x16, 0x17 or 0x18 accordingly.

Note that the OL2385 boards for each of these respective regions are different. For

example: RCZ2 and RCZ4 uses external PA whereas, RCZ3 uses 27.6 MHz external

TCXO. However, the OL2385 firmware supports all four regions. However, the system

as a whole will only work if you choose the appropriate region on the terminal for the

hardware.

11.The rest of the commands are self-explanatory and depend on your choice of testing

tool. For example, a Spectrum analyzer might need a Continuous wave command,

SIGFOX base station might need a Send payload command or SIGFOX SFXIQ

P1 certification tool might need a Send test mode command. If required, refer to
