I'm tring to pair the redmi airdots and an old Bluetooth headfones (that I had already paired with my cell phone but then removed this known device) and nowadays it stoped to recognise new Bluetooth devices in my cell phone. What can I do to solve this?

Hi joao.parreira, Please make sure to update to the latest firmware version WW-16.0615.1912.115. Please try resetting your network settings and try again. (Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth) If the problem still appears, please provide the Bluetooth headphones brand and model that cannot be recognized. Thank you 🙂
