"remote dfu invalid crc error" on master control panel of android

[jignesh]

i am using latest "master control panel" v4.0.5 and latest "nRF tool box" v1.16.2 and use sdk 5.2(its compulsory) soft-device s110 v6.2.1(its compulsory) and PCA10028 with nrf51422 256kb QFAC and custom board nrf51822 128kb QFAB(using by memory set-up) and keil v 5.13

when i have been compile blinky code and generate zip file using nrfutil.exe. And then load .bin and .dat file by using "master control panel". so, it's denoted "remote dfu invalid crc error" type message after 99% loading complete..

please answer of my question as soon as possible...

Hi,

Bootloader from SDKs prior to version 7.x.x doesn't implement the check the init file (crc, and versions). So in your case you should only provide the .hex file in nrftoolbox/ master control panel (pc version is not backwards compatible), and not a "distribution" file.
