Hello I tried to do a application update with my own key and it does work.
But then I tried to create zip with all 3 parts: APP+BL+SD (application+BootLoader+SoftDevice) and that did not work. It copied something but then it end up in DfuTarg. And application was not updated (SD and BL was same in DevKit and in dfu.zip).
Do you know what can be wrong?
I used BL from example: bootloader_secure
I used APP from example: ble_app_hrs_freertos
I used DL from SDK12 package: s132_nrf52_3.0.0_softdevice.hex
my priv key was: -----BEGIN EC PRIVATE KEY----- MHcCAQEEIKjaCIfnnMU5VMsQ4/NCFAQXsZ9p6O3CHdxD2m7tQUceoAoGCCqGSM49 AwEHoUQDQgAE4gRlWO8tIPwDUTLE+47AvKdLNz6GA2CRkAPJPkPwXBwidZTkvJ4s NZqST0+RSH1yufVzVwRX4+HCyU/VmFyRLg== -----END EC PRIVATE KEY-----
my public key was: __ALIGN(4) const uint8_t pk[64] = { 0x1c, 0x5c, 0xf0, 0x43, 0x3e, 0xc9, 0x03, 0x90, 0x91, 0x60, 0x03, 0x86, 0x3e, 0x37, 0x4b, 0xa7, 0xbc, 0xc0, 0x8e, 0xfb, 0xc4, 0x32, 0x51, 0x03, 0xfc, 0x20, 0x2d, 0xef, 0x58, 0x65, 0x04, 0xe2, 0x2e, 0x91, 0x5c, 0x98, 0xd5, 0x4f, 0xc9, 0xc2, 0xe1, 0xe3, 0x57, 0x04, 0x57, 0x73, 0xf5, 0xb9, 0x72, 0x7d, 0x48, 0x91, 0x4f, 0x4f, 0x92, 0x9a, 0x35, 0x2c, 0x9e, 0xbc, 0xe4, 0x94, 0x75, 0x22 };
my batch file was:
set APP="d:\Python27\Scripts\nrfutil.exe"
set HEX="examples\ble_peripheral\ble_app_hrs_freertos\pca10040\s132\arm5_no_packs\_build\nrf52832_xxaa.hex"
set BL_HEX="examples\dfu\bootloader_secure\pca10040\arm5_no_packs\_build\nrf52832_xxaa_s132.hex"
%APP% pkg generate --application %HEX% --application-version 0xff --softdevice s132_nrf52_3.0.0_softdevice.hex --bootloader %BL_HEX% --bootloader-version 0xff --hw-version 52 --sd-req 0x8c --key-file priv2.pem out.zip
I tried to update with android K + nRF connect. I also tried to use MCP I did connect to DfuTarg I list services but DFU button was not enabled.
