how to Switch between over-the-air and uart bootloader mode?

balaji

Hi, How to integrate both over-the-air and uart bootloader application for an device? We have a custom board with nrf51822 chipset, and we need to implement the firmware update process, which can support both over-the-air and usb to uart type firmware update. Since we not yet tested the uart bootloader application, we dont have clear idea on it (like, how to make it enter into the bootloader mode). Can anyone suggest us how to handle this?

our requirement as follows, If the device is connected through the usb, and if the user want to update the firmware, the device should enter into dfu_dual_bank_hci (uart) bootloader mode, and do the firmware update.

And if the device is connected through ble, user should make it enter into the dfu_dual_bank_ble (over the air) bootloader mode by writing some value through the special characteristics created for it, and should do the firmware update.

Regards, Balaji

    I'm developing a spi+ble bootloader on a custom board with a nrf51802_xAA on SDK11. As a starting point i want to have a functional uart+ble bootloader so i merged both examples. I have found myself in the same issues described above. However after the compilation is complete succesfully and i try to load the program the the flasher ends spitting the following error:

    Program Size: Code=16304 RO-data=468 RW-data=312 ZI-data=5140

    Any hints ?
