secure bootloader and softdevice update through OTA on nrf51822 sdk12.3.0

[vernon]

Hello,

I know how to update the application through OTA at the moment, I do the following steps:

1. set the device run in DFU mode by writing 0x01 in Experimental Buttonless DFU characteristic.

2. send the zip file to the device by using nrf connector app.

3. application update successfully.

however, I don't know how to update the bootloader and softdevice, can you have a guide pdf on how to update that?

Thank you in advance.
