[Daniel.Chiu]

Hi guys

I have a custom board with NRF51422QFAA, load "s310_nrf51422_2.0.1_softdevice", program on "nRF51_SDK_7.2.0"

the bootloader I used is "dual_bank_ble_s310"

change settting:

IROM1 0x3C000 0x3C00

IRAM1 0x20002C00 0x1380

IRAM2 0x20003F80 0x80

DFU_APP_DATA_RESERVED 0x1000

when DFU via dongle by computer, it's work fine. but when used with phone, no matter MCP or NRF-toolbox, after saw connecting screen, the device disconnect immediately and back to advertising.

How to get it work?

Did you create a distribution package (.zip) of the application you tried to upload. Note that PC MCP will accept .hex files, but creates the .zip including the init file "under the hood".

Thanks! I created the distribution package and DFU successful.
