Dfu connection failed

[Inspectron]

I included the DFU service in my project. With the MCP on my computer it is working fine.

But when I try to perform the DFU over the MCP(v.3.4.1) app on my android device, then it will not work.

Here the error log:

My Setup:

-SDK8.1

-SD 8.0

-Bootloader from SDK 8.1

-nRF51DK

Any ideas?

Seems to be a problem on the device. Because on my Note 4 its working always.

Hi Inspectron,

If you only test with the bootloader (with no application) would you be able to update your application ? Have you set IS_SRVC_CHANGED_CHARACT_PRESENT to 1 in main.c of your application ?

Have you tried to test with our ble_app_hrs_withdfu example ?

[Inspectron]

I tested it without application and this is working. But when I try it to update again(when application is already on chip), then it wont work. Yes, IS_SRVC_CHANGED_CHARACT_PRESENT is set to 1. I will now test with ble_app_hrs_withdfu example.
