Why I am getting a GAT ERROR when uploading zip file through DFU tool

[mc]

Hi,

I am struck with the problem of GAT ERROR when I upload my application zip file through Nordic nRD ToolBox in Android.

These are my steps:

1. I load the S310 softdevice 3.0.0
2. I load the bootloader code from the example of SDK9 sample. Bootloader code is dfu_dual_bank_ble_s310_pca10028
3. Run the code using the Nrf51 dev kit
4. I make a zip file using the ble_app_hrs_s310_with_dfu_pca10028 code. This is my instruction: nrfutil dfu genpkg app.zip --application HRM_DFU2.hex --application-version 0xFFFFFFFF --dev-type 0xFFFF --dev-revision 0xFFFF --sd-req 0xFFFE
5. I upload this zip using DFU of nfr toolbox and don't have any problem.
6. When the download file start advertizing, I make another upload with my using the same zip file but I always have a problem. The error message is GATT ERROR.

As far as I know #5 should work. But I always have a problem regarding GATT ERROR. Is there some thing I miss configuring the APP example or the bootloader to work?

I also tried the samples of S110 and its zip file and I don't experience this kind of problem

-thanks MC

Hi, please try to upload the attached .zip and see if you get the same error using the steps you described above. I didn't manage to reproduce the GATT error, but it shouldn't be any difference compared to the s110 version.
