This Bluetooth remote aims to replicate Canon's BR-E1 behavior while adding key features like fully programable time-lapses that most Canon cameras lack! Fortunately, M5Stack proposes a nice little inexpensive development board that perfectly fits our needs, the M5Stick-Cplus.
The BR-M5 has been primarily developed for the Canon M50 Mark I, which misses a descent timelapse mode that can do long exposures. The shutter speed option in M50's timelapse mode is indeed limited to 1/30s. Furthermore, the M50 doesn't have any shutter release port to plug classic intervalometers. No official Bluetooth, WiFi, or tethering tools currently offer time-lapse capabilities.
- Install Visual Studio Code and the PlatformIO IDE extension.
- Clone this repository -
git clone https://github.com/ArthurFDLR/br-m5-, open it as project in PlatformIO and upload -Ctrl+Alt+u- to a M5Stick-Cplus connected to your PC.
- Power on by pressing the left-side button and power off with a 6 seconds press on the same button.
- You can connect to your Canon DSLR as soon as the remote is powered on and displays Pairing in progress.
- To change the interval, press the right-side button for half a second and use the same button to increase and the center button to decrease the timelapse interval. Once set, press the right-side button for half a second again.
- Start and stop time-lapses using the center button. The remote takes single shots if the interval is set to 0 seconds.
- Fix connection reliability issues.
- Auto connection to camera when remote start-up.
- Add battery level indication.
