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.
