I got it working, but only the first time. It means when I erase chip and download S110 and bootloader.hex, then I am able to download firmware over the air. But when I try to download application for the second time I don't get (I push BUTTON7, to enter bootloader mode as written in the spec). Do you have any ideas?

Yes, Ole, it is working, when the button is pushed while powering up. Is it possible to enter bootloader mode without shutting down the system? For instance when I write characteristic for entering bootloader, send data which means "enter bootloader", without pushing buttons.
