Over Air Download

[Konstantin]

Hi,

can someone post tutorial how to do Over Air Download? I mean new SDK 4.4

I get error from cmd: ImportError: No module named intelhex

Regards, Konstantin

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?

You have to keep this button pressed while the device is powering up, but when doing so, I don't have any problems with this. Does your regular application start even when holding button 7 when starting?

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.
