Error (0x85): GATT ERROR in DFU bootloader during init packet

[remon]

Hi,

I am getting the GATT ERROR during init packet stage  during firmware upgrade. I am using SDK 14.2 and  nRFConnect application on Samsusng Galaxt S8. It looks like I am stuck. I need help do debug it further. Below is the log.

Hi Remon, 

Do you have the issue all the time when you try to do DFU ? Have you tried to test with the stock example in the SDK ? Could you check if there is any assertion on the bootloader side ? 

Could you try to follow the guide here and let me know if you see the same issue ? 

[remon]

Hi Hung,

Thanks for the reply. Yes I used the mentioned guide to create the bootloader  as well as the package. I didn't try the stock examples because  I thought that the private key used in bootloader and example package will be different. I will check for assertion. Please confirm if you have DFU working in SDK 14.2 for nRF5832 on PCA10040. I am using arm gcc compiler version 7.2.1.

Thanks

[Hung Bui]

Please try to follow the guide. 

We have many customers using SDK v14.2 on nRF52832 with no problem. 

[remon]

Yes the compiler version was the issue. I used the compiler mentioned in the guide and it worked. Thanks
