DFU OTA on a custom board using nrf51 DK board

[Nilesh Bhavsar]

Hi,

I had done OTA DFU update on nrf51 DK Board using SDK11 version.

Now i wish to do same thing with other custom board which is having nrf51822QFAA. For that, my hardware connection is as per below.

   nrf51 DK                     nrf51822QFAA
   VTG + VDD                         VCC
   GND + GND                         GND
     SWDIO                          SWDIO
     SWDCLK                         SWDCLK

Then using nrfgo studio application, First erase then program softdevice and bootloader file of the SDK11. But no effect shown by my custom board.

If i have do same thing with nrf51 DK board and it's advtise its name DFUTEST and then i connect it for transfer my application using nrfconnect mobile application.

Please help me for solve it.

Thanks

Hi,

I apologize for the late response due to some other technical emergency.

i am using RL51822 A1 module and I don't know how to identify that external crystal is available or not in that. But module has nrf51822QFAA type chip and its having external crystal of 32KHz.

Also i am trying to build application file downloaded from mbed compiler using nrf51 Dk then it's done successfully. or i connect this module using nrf51 Dk through in nrfConnect app. then also it shows me that board successfully and done all the thing like erase, program softdevice and bootloader. but the actual effect is not shown by my module like when i burn same bootloader abd softdevice in nrf51 Dk board then it's advtise DFUTEST but my custom module not.
