Rep trap pcb

Openthing 2 - RepTrap

The RepTrap is a "motion detector" and camera trigger designed to detect small and/or cold-blooded animals such as frogs, lizards, birds, and other wildlife. It doesn't detect motion directly but instead identifies changes in height within the range of its four Time-of-Flight (ToF) sensors. Any height change within this range triggers a connected camera's shutter.

BLE

The device and software is Bluetooth ready but it is currently missing an App. Here are commands which can be send to configure and change the device:

• Bluetooth Service [0x7017]
  • Status Characteristic [0x701C] Description: Refelcts the current device status as a string Values: running calibrating
  • Command Characteristic [0x7018] Description: Accepts specific device commands Values:
    • stop: Stops the BLE Service on the device
    • calibrate: Triggers a re-calibration of the device
    • xtalk: Triggers an cross-talk and offset calibration of the device (only needed for manufacturing, should not be used)
    • trigger: Triggers the camera shutter and focus signal
  • Config Characteristic [701D] Description: Using this characteristic you can configure the device (experimental). You can send a 3 Byte payload consisting of the type (first byte) and tzhe data(second and third byte). Example [0xA0, 0x00, 0x00] Type 0xA0 Signal Threashold with value 0 Values:
    • 0xA0 - Signal Threshold
    • 0xA1 - Sigma Threshold
    • 0xA2 - Time to Measure
    • 0xA3 - Measure Interval

Note: The config characteristic is experimental. The limits of the values might not be checked or some value combination might lead to an unresponsive sensor. A re-flash of the firmware might be needed to fix the device. You can read the datasheet of the ToF Sensor to get the details of this values.

Note: If you want to power the device permanently via USB-C the BLE Service will be started once you boot the device with USB-C connected. You can send teh command to stop the BLE Service to save energy.
