My apple magic keyboard is acting weird.

Hi, my magic keyboard 1 has recently started to type by itself. When i am typing, sometimes the last letter i typed will continue until i hit several keys. Its like a phone hanging, then the keyboard disconnects. This has never happened to me before.

I will have to manually reconnect it and this is quite frustrating, as i have to send e mails all day long. BTW- i am using this on my ipad pro. How can i fix this?

Your help will be much appreciated.
