Remote DFU invalid CRC error in nRF ToolBox

[Nilesh Bhavsar]

Hi,

I am using nRFToolBox into my smart phone of v4.4.2(kitkat).

I am trying to update my program using OTA through my phone.

But when i am trying to send dfu_test_app_hrm_s130.zip file then getting error of "Remote DFU invalid CRC error".

Also i don't know how to generate .dat file from hexor bin file.

Also if i generate this hex file from ARMmbed then what additional changes required?

Maximum flash memory is 256kB. So, It is not possible to flash 300kB.
