5.1. General Commands
5.1.1. PF
—Query or configure the profiles
5.1.1.1. Description:
This command can query or configure the profiles of Bluetooth module. Once configured, the configuration will take effect
immediately and until the next time the module is configured by this command. It means the Bluetooth module will
remember the configuration, and even if the Bluetooth module has been powered off, the configuration will not be lost. If
the new configuration is adopted by the Bluetooth module, the module will perform a reboot, the non-memorable settings
will return to their default value. Therefore, it is recommended to send this command first if necessary.
If the parameter is not presented, the Bluetooth module will report current profile configuration by the Indicator PF.
