Call requires permission which may be rejected by user のエラーが解決できない

実現したいこと

AndroidとArduinoでBluetooth通信をしたい

発生している問題・分からないこと

checkPermission を追加するのは理解しているが、調べ方が悪いのか試してみても一向に解決しない

エラーメッセージ

error
1Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with `checkPermission`) or explicitly handle a potential `SecurityException`
