Canon BR-E1 remote blinking red when used with Canon Digital Rebel SL2: Bluetooth repairing

My Canon BR-E1 remote was blinking red when I tried to use it with my Canon Digital Rebel (DR) SL2, aka EOS 200D. Perplexity ai answers were all incorrect.

This is a Bluetooth remote. The red blinking is an error code related to pairing. You probably need to repair, though it doesn't hurt tI o change the remote battery.

Forget the web and forget ai, you need the PDF manuals for your SL2 and the BR-E1. But if you can't find them:

1. On Camera: Wireless communication settings.
2. Change Bluetooth function: setting to "remote".
3. If it still doesn't work you need to repair. Choose "Check/clear connection info"
4. Now choose Pairing.
5. On remote press and hold W/T for 3 seconds and release. LED flashes briefly.
