A wireless shutter trigger for a DSLR camera can come in handy in many situations. And if you already own an Android device, you don’t have to splurge on a dedicated remote trigger. To turn an Android device into a flexible tool for triggering the shutter wirelessly you need three things:
- The DSLR Remote app installed on your Android device
- TriggerTrap dongle and cable combination for your specific DSLR model
- Generic Bluetooth A2DP receiver (can be purchased on eBay)
Start with installing the DSLR Remote Control app on your Android device. Connect then the Bluetooth receiver to the DSLR camera using the TriggerTrap cable as shown below. Enable Bluetooth on the Android device, and turn the Bluetooth receiver on. On the Android device, switch to Settings → Bluetooth and pair the device with the receiver.
Next, configure the DSLR Remote app. The exact configuration profile depends on the particular receiver. In most cases, you only need to specify the appropriate cable type in the app’s Settings section. To do this, launch the DSLR Remote app, switch to the Settings section, and set the Remote Type option to Cable S. Close the settings screen, switch to the Remote section and press the S button. This should trigger the camera’s shutter. If this doesn’t work, then try enabling the Bluetooth option, or set the Remote Type option to Cable A.
