How to transmit continuous wave (CW) for factory testing (TX power & frequency offset) on STM32 + MM6108 custom module?

General

We have designed a custom module based on STM32 MCU + MM6108 (connected viaSDIO) and are currently setting up the factory production line / RF calibration test.

To verify TX output power and calibrate the frequency offset (crystal trim / ppm error) using a spectrum analyzer, we need to configure the MM6108 into Continuous Wave (CW) / Single Tone mode.

Could you please advise:

SDK API / Test Mode: Which specific API function, CLI command, or manufacturing test firmware (DUT/FT mode) in the MM6108 MCU SDK should be used to enable and disable continuous unmodulated CW transmission?

Hi @weili

Can you take a look at APPNOTE 43 Wi-Fi HaLow RF Test Guide | Application notes | Morse Micro documentation and see if it meets your requirements for RF test.

If so, you will need to reach out to support@morsemicro.com for access to the RF test utilities, as these are not available to the general public.

Hi ajudge.

We have signed an NDA with Morse Micro and previously obtained a radio test utility. After porting the source code to our MCU, we can now perform CW testing. Thank you for your reply.
