The manufacturer has prepared the source code of the application allowing to process data from BBMagic modules. They are available on the manufacturer's website in theDownloadtab, additionally prepared a short guide to working withbbmm_scanner appplication. |
Operation of BBMagic Dimmer Power module - wireless AC controller
When the BBMagic PWM starts up, it sends"ALIVE"information every 60 seconds. If the module receives a change request, it sends the message "ALIVE" immediately after the received adjustments have been made. The module has the option of activating the controlled device for 15 minutes after starting up the BBMagic Dimmer Power, configurable via pin 17. The buffer content is defined in a filebbmagic_lib.h library version 2.0. Sample programs can be found onmanufacturer's website.
