The module is equipped with a relay with load capacity up to 10 A controlled by 12 V.

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 manual withbbmm_scanner appplication.

Operation of BBMagic Relay Power module - Wireless controller with relay

When the BBMagic Relay Power starts up, it sends "ALIVE" information every 60 seconds.If the module receives a request to switch the relay(s) on or off, it sends the message "ALIVE" immediately after the task is completed. The content of the buffer is defined in the file bbmagic_lib.h of the library version 2.0. For example, you can find examples of programs on themanufacturer'swebsite.

bbmm_buf[BBMAGIC_DEVICE_TYPE]. Specify the type of module that sent the data. In this case "BBMAGIC_M_RELAY".
bbmm_buf[BBM_RELAY_V_SUP]. Module supply voltage. To obtain the voltage in volts, divide the obtained value by 71.
bbm_buf[BBMAGIC_RELAY_ADV_TIME]. The time after which the "ALIVE" message queue is sent. To hold the time in seconds, multiply it by 2.
bbm_buf[BBMAGIC_RELAYS_STATE] The four youngest bits define the state of the relays. Bit set=relay on, bit zeroed=relay off. Bit0 - Relay0...Bit3 - Relay3.
bbmm_buf[BBM_RELAY_CHIP_TEMP] Chip temperature in degrees Celsius (coding U2).
bbmm_buf[BBM_RELAY_LIGHT]. Lighting level. Given in the range from 0 to 255.

bbmm_buf[BBM_RELAY_FIRM_0].

The firmware version number of the module - a younger byte.

bbmm_buf[BBM_RELAY_FIRM_1]]

Module firmware version number - older byte.

bbm_buf[BBMAGIC_DEVICE_ADDR_0]]

Module address, youngest byte 0 -LSB.

bbm_buf[BBMAGIC_DEVICE_ADDR_1].
