!BZBUZZ
Supporting chipsets:
• MDM6200
Generate frequency on buzzer pin
Generate a pre-defined frequency on the module’s BUZZER_EN pin using the modem’s
internal PWM (pulse wave modulation) generator.
Note: If BUZZER_EN is configured as a PWM output, use this command to generate a
specific frequency, or use !BZBUZZPLAY to generate a predefined melody.
Usage:
• With BUZZER_EN configured as PWM output, use this command or !BZBUZZPLAY
to control the signal:
Execution: AT!BZBUZZ=<status>, <freq>
Response:
OK
Purpose: Play (or stop playing) the frequency on the PWM output.
• With BUZZER_EN configured as GPO (general purpose output), use this command
to control the signal:
Execution: AT!BZBUZZ=<status>
Response:
OK
Purpose: Set the BUZZER_EN pin to high or low.
• Query: AT!BZBUZZ?
Response:
!BZBUZZ: <status>[, <freq>]
OK
Purpose: Display current buzzer output state.
• Query list: AT!BZBUZZ=?
Purpose: Display valid values for <status> and <freq> parameters.
Parameters:
