A reedswitchis required for proper operation.

Operating modes BBMagic Magneto - Wireless magnetic field sensor

To set the mode of operation, please:

  1. Turn off the power supply to the module.
  2. Press the built-in button.
  3. Turn on the power while holdingdown the button.
  4. Hold the button while counting down the LED flashes: 1 flash = 1 operating mode, 2 flash = 2 operating mode and so on.
  5. Release the button with the selected operating mode.
  6. The LED will go out for about 2 seconds and then flash several times depending on the mode set.

Operating mode Data transmission period "ALIVE

1

ALIVE" information is sent every 30 seconds.

2

ALIVE" information transmitted every 60 seconds.

3

ALIVE" information transmitted every 3 minutes.

4

ALIVE" information transmitted every 5 minutes.

The manufacturer has prepared the source code of the application to process data from BBMagic modules.

They are available on the manufacturer's website in thedownloadsection, additionally prepared a short manualwith the bbm_scanner appendix.

Communication of BBMagic PWM module - wireless PWM signal controller

The module communicates viaBluetooth Low Energy,the communication is encrypted and signed digitally with the AES-128 symmetrical block code. The device can communicate directly with Raspberry PiviaBluetooth Smart.

The reed switch is not included. Please order it separately.

Operation of BBMagic Magneto module - wireless magnetic field sensor

When the BBMagic Magneto starts up, it sends the standby information "ALIVE" at the time set during the configuration mode. The exception is the detection or loss of magnetic field, then it is sent immediately after the status change. The buffer content is defined in the file bbmagic_lib.h. Sample programs can be found onthe manufacturer's website.

bbmm_buf[BBMAGIC_DEVICE_TYPE] Specify the type of module that sent the data.
bbm_buf[BBM_MAGNETO_FLAGS] Flags informing about magnetic field detection (oldest bit) and status of four digital inputs (four younger bits). The set BBM_MAGNETO_MAGNET_MASK flagindicates magnetic field detection.
bbm_buf[BBM_MAGNETO_V_SUP] The current supply voltage of the modulemust be divided by 71 to obtain the voltage in volts.
bbm_buf[BBM_MAGNETO_ADV_TIME]. Time to send another message from the module. To get the time in seconds, multiply it by two.
bbm_buf[BBM_MAGNETO_CHIP_TEMP] Temperature given in degrees Celsius.
bbmm_buf[BBM_MAGNETO_LIGHT] Lighting level, Range 0 to 255.
bbmm_buf[BBM_MAGNETO_ADC_1_MSB]bbm_buf[BBM_MAGNETO_ADC_1_LSB] Voltage level at input ADC_1 in mV, older and younger byte.
bbmm_buf[BBM_MAGNETO_ADC_2_MSB]bbm_buf[BBM_MAGNETO_ADC_2_LSB] Voltage level at input ADC_2 in mV, older and younger byte.
bbmm_buf[BBM_MAGNETO_WORKTIME_0]]

The module's operating time since the last power on is given in seconds - youngest byte 0.

bbmm_buf[BBM_MAGNETO_WORKTIME_1]. The module's operating time since the last power on is given in seconds - next byte 1.
bbmm_buf[BBM_MAGNETO_WORKTIME_2]. Module operating time since the last power-on in seconds -nextbyte 2.
bbmm_buf[BBM_MAGNETO_WORKTIME_3]. Module operating time since the last power-on in seconds -nextbyte 3.
bbmm_buf[BBM_MAGNETO_FIRM_0]. Module firmware version, junior byte.
bbmm_buf[BBM_MAGNETO_FIRM_1]] Versionmodule firmware, older byte.
bbm_buf[BBMAGIC_DEVICE_ADDR_0]] Module address - youngest byte 0 - LSB.
bbm_buf[BBMAGIC_DEVICE_ADDR_1]. Module address - next byte 1.
bbm_buf[BBMAGIC_DEVICE_ADDR_2]. Module address - next byte 2.
bbm_buf[BBMAGIC_DEVICE_ADDR_3]. Module address - next byte 3.
bbm_buf[BBMAGIC_DEVICE_ADDR_4]. Module address - next byte 4.
bbm_buf[BBMAGIC_DEVICE_ADDR_5]. Module address - oldest byte 5 - MSB.
bbm_buf[BBMAGIC_DEVICE_RSSI]. Power of received radio signal in dBm.

Configuration of radio transmission signaling:

  • Connection to ground: The built-in red LED indicates radio transmission.
  • No connection: the LED is switched off. The signalling pulses appear on pin 15. Alternatively, the LED can be connected with a serial resistor to pin 15 and 16. It is recommended to use a resistor between 1 kΩ and 4.7 kΩ.
