Sean Dear Sean,
After a thorough review of the module's programming manual and command set, we must confirm that there is no AT command available to switch the SPK (speaker) output from Class D to Class AB amplification.
To better understand your requirements and see if we can offer a viable alternative, could you please share more details about the specific functionality you are trying to achieve by making this switch? For example:
- Are you looking to reduce power consumption?
- Is there a need to improve audio fidelity or reduce EMI (electromagnetic interference) in a specific scenario?
- Are you trying to solve a specific audio noise issue?
Understanding your end goal will allow us to investigate if there are other commands (e.g., related to audio gain, EQ settings, or power management) or potential hardware solutions that could effectively meet your needs.
We appreciate your understanding and look forward to helping you find the best possible solution for your application.
