Hi,

The latest issue seems away from the original scope and duplicated by Combining MQTT over wifi with OTA BLE which is handled by my colleague, so I would suggest you back to continue discussion in that case.

Hi Amada, i tried going back from scratch and combined Exercise 3 – FOTA over Bluetooth Low Energy and Exercise 2 – DFU over USB, adding external flash & custom keys and i got my application to work perfectly fine.

now i tried adding FOTA over BLE to an MQTT application i created, i did the same thing but the application is stuck on the bootloader

so i don't know is this because of the excessive RAM usage of the application ( this is what i get when i build RAM: 233952 B 256 KB 89.25% ), or is there something wrong i did.

Thanks in advance,

have a nice weekend.

Hi,

The error 9 means MGMT_ERR_ECORRUPT means Corrupt. This error code signifies that the operation encountered corruption. The exact cause of this error can vary, but it generally indicates that the data or resource being accessed by the operation is in an unexpected or invalid state.

I suspect it might be from smp_process_request_packet in smp.c which says MGMT_ERR_ECORRUPT if the buffer starts with non-SMP data header or there is not enough bytes to process header.

Are you updating via BLE or serial recovery? Could you upload the mcuboot config file?

Hi,

Are you using nRF52840DK? If so, Place the following files under boards folder

devzone.nordicsemi.com/.../2476.nrf52840dk_5F00_nrf52840.conf

devzone.nordicsemi.com/.../4442.nrf52840dk_5F00_nrf52840.overlay

Place the following files under child_image/mcuboot/boards

devzone.nordicsemi.com/.../2476.nrf52840dk_5F00_nrf52840.conf

devzone.nordicsemi.com/.../4442.nrf52840dk_5F00_nrf52840.overlay

If you are not using nRF52840DK, rename the files for your board name.

Hi Amanda, yes i am using the external flash memory and i followed the instructions but the software just won't start, as i soon as i flash it this is all i get :

*** Booting nRF Connect SDK v2.5.2 ***

then it freezesn is there an OTA DFU exemple using the external flash memory i can base my application on?

Thanks in advance.

Kind Regards,

Hi amanda,

thank you for your response, unfortunally the solution provided in that post didn't work for me (i tried changing BOOT_MAX_IMG_SECTORS value but nothing works) so i'll be waiting for your support after the holidays.

Hi,

Due to the Easter holidays in Norway, we are less staffed than usual. You can expect a delayed answer.
