Hi,

I will try to replicate this again with a PDK. PCA10000 has been deprecated and is not supported by nRF connect.

List of supported devices:

PCA10056 nRF52 Development Kit
PCA10040 nRF52 Development Kit
PCA10059 nRF52 USB Dongle
PCA10028 nRF51 Development Kit
PCA10031 nRF51 Dongle

Hi,

Thanks for the information.

What I have is PCA10056 0.9.3 2017.46

Yes, I have another dongle(PCA10000 V2.1.0) But, there is another issue with nrf connect.

Whenever it connects with dongle on nrf connect, screen is switched to while blank.

So, I couldn't do anything with that dongle. So, I tried with PCA10056 board.

Thanks,

Hi,

Thanks for the log, it seems to confirm the problem is on the nRFconnect/connectivity side. Can you provide the board version number for your PDK? It's printed on the sticker on the interface MCU (e.g., pca10056 v.11.0). Also, do you have another development kit/dongle that you can try with?

Hi,

Yes, I still get the same error. But, I tried with mobile application as you mentioned.

It looks that updating firmware is successful.

RTT logs are attached from both case( using nrf connect on windows and on mobile application)

By the way, nRF52840-Preview-DK board is used for connectivity device.

Thanks,

Hi,

Are you still seeing this issue. The problem seems to be intermittent, I managed to reproduce it last week, but not now. Could you try to erase the connectivity device (nrfjprog -e) and let nrf connect re-program it, then check if you still get the same error. Also, can you provide the RTT log output from the DFU target (log is enabled in pre-compiled .hex)?

Note that you can do DFU with nrf connect on android/ios as well.

Hi,

It looks like you have done everything correctly, but the log indicates that the signature may be invalid. Please try to follow these steps and see if you get the same error

1. Program devzone.nordicsemi.com/.../secure_5F00_bootloader_5F00_ble_5F00_s132_5F00_pca10040_5F00_debug.hex. E.g. nrfjprog --program secure_bootloader_ble_s132_pca10040_debug --chiperase -r

2. Then upload this package in nRF connect: devzone.nordicsemi.com/.../ble_5F00_app_5F00_buttonless_5F00_dfu_5F00_without_5F00_bonds_5F00_s132.zip
