• This command is not necessary for RF evaluation of the board, but can be the root

cause of not seeing the transmission of the frame over the radio, even though there is

no error reported.

7.3 Frequently used RF test cases using SPI commands

Check the Section 5.4.1 "Setting up KL43Z board with terminal program" and Section 7.2

"OL2385 Transceiver Initialization Sequence" before you proceed to start performing the

following tests.

7.3.1 Unmodulated continuous wave

1. Press the reset button on the KL43Z to start from the beginning (optional).

2. Choose Send Wake up: Type

1, and then press Enter. (This step is optional and not

required if there is no device reset).

3. Choose the region "Change to RCZXX": Type

15 or 16 or 17 or 18, and then press

Enter.

4. The next steps will program the opening center frequencies of each region into the

OL2385.

a. Type

0 for zero attenuation steps for uplink TX power, and then press Enter.

b. Type

0 for 55.2 MHz crystal type or type 1 for TCXO, and then press Enter.

c. Type

3 for SIGFOX repetition frames, and then press Enter.

d. Type

0 for 14 dBm PA level, and then press Enter.

5. Choose Continuous wave command: Type

b, and then press Enter. Now type 1, and

then press Enter to start continuous wave. The CW should be on and you can check

this on a spectrum analyzer.

6. If you want to see the continuous wave on a different frequency, choose Continuous

wave command: Type

b, and then press Enter. Now type 0, and then press Enter to

stop the continuous wave first. The CW should be off and you can check this on a

spectrum analyzer.

7. Use the command Set UL Frequency: Type

9 press Enter, type frequency value in Hz

and press Enter. If you do not want to change the frequency, move to the next step.

8. Choose Continuous wave command: Type

b, and then press Enter. Now type 1, and

then press Enter to start continuous wave. The CW should be on and you can check

this on a spectrum analyzer.

Note: If you want to see the CW on a different frequency, stop the CW first. Then change

the frequency to your desired frequency and then start CW again.

7.3.2 Modulated continuous wave

1. Press the reset button on the KL43Z to start from the beginning.

2. Choose Send Wake up: Type

1, and then press Enter.

3. Choose the region "Change to RCZXX". Type

15 or 16 or 17 or 18, and then press

Enter.

4. The next steps will program the opening center frequencies of each region into the

OL2385.

a. Type

0 for zero attenuation steps for uplink TX power, and then press Enter.

b. Type

0 for 55.2 MHz crystal type or type 1 for TCXO, and then press Enter.

c. Type

3 for SIGFOX repetition frames, and then press Enter.
