Here is the link to the mergehex User-guide on Infocenter.

I recommend that you use mergehex( part of the nRF5x Commandline Tools, available here).

I am merging the two files to include DFU service from ble_hrs example to my code written in arduino ide.

Hello,

I merged two hex file:

Blink.hex compiled using arduino IDE
nrf51422_xxac_s130.hex from \installed folder...\ble_app_hrs using srec_cat.exe

I used this command: srec_cat.exe nrf51422_xxac_s130.hex -intel Blink.hex -intel -offset -MAximum-addr nrf51422_xxac_s130.hex -intel -Output_Block_Size=16 -o output.hex -intel and successfully generated "output.hex" file

I tried loading this firmware using nrfgostudio with s130 softdevice from SDK11.

Few observation:

When I first mention Blink.hex file in srec_cat command like this: srec_cat.exe Blink.hex -intel nrf51422_xxac_s130.hex -intel -offset -MAximum-addr Blink.hex -intel -Output_Block_Size=16 -o output.hex -intel the output.hex behaves as if only Blink.hex is uploaded and nrf51422_xxac_s130.hex has no effect.
opposite to above (nrf51422_xxac_s130 when mentioned first in cmd)

Am I going in right direction?

Yes, if your comfortable with going from arduino code to mBed code, then this should work.

Hello,

Thank you for the reply. I referred to this link of redbear labs that uses MDBT40: github.com/.../BLE_SimplePeripheral.ino

This code uses DFU service and has .cpp source as you mentioned for the DFU service. Further this link explains about FOTA: developer.mbed.org/.../Firmware-Over-the-Air-FOTA-Updates

This should work in my case right?

Hi Dhiraj,

the Infocenter guide you're referring to explains how to add DFU support to an application that is written in C, i.e. using our SDK directly and not through a 3rd party library. Thus, including the 3 files mentioned in the guide will not work.

I took a quick look at sandeepmistry's arduino-BLEPeripheral library and it appears that you will have to create the DFU service using the .cpp source, like sandeep did for the HID example.

If you need support for Device Firmware Updates in your project, then I would recommend moving from the Arduino IDE and Sandeep's Library to using our SDK in Keil, Eclipse or Segger Embedded Studio.
