How to use the OTA in SDK?

[Alice]

Hi all,

I test the DFU as follow:

1. erase chip, program "s110_nrf51822_5.2.1_softdevice.hex"
2. program "bootloader" by using nrfjprog.exe
3. "DfuTarg" can be found in Master Control Panel. 4.On the Master Control Panel,Right-click the "DfuTarg" and then I can see over the air DFU.Then I select select a "ble_app_proximity.hex" 5.Wait for a while and 100% done.

This can be done successfully. I have another problem.It seems that the bootloader will be erase when firmware update completed.So what should I do if I want to update the firmware again?

A bootloader hex file can be programmed like any other, using the --program parameter.

However, if you have trouble getting this working, please post a separate question instead of messing up this one.
