problem with DFU OTA

[marcag]

I had a setup where I could DFU OTA a NRF52832 based board

I moved to a NRF52840 based board and now during the OTA DFU I get messages like this 

I did try a new bootloader based on the PCA10056 rather than the PCA10040 wth same result

I did not change the way I generate the package to be uploaded

Any ideas where to look. Thanks

Hi, 

What is the softdevice version and command you are using?

Thanks

I am using SoftDevice 332 (was using the same with the NRF52830).

I am using the NrfConnect app on IOS to do the upload so now command per se (if I understand correctly)

Hi marcag, 

What is the command used to generate the package?

-Amanda H.

[marcag]

nrfutil pkg generate --hw-version 52 --application-version 1 --application ble_ant_app_hrm_pca10040_s332.hex --sd-req 0x9B --key-file private.key app_dfu_package.zip

Hi marcag, 

I moved to a NRF52840 based board and now during the OTA DFU I get messages like this 

Are you using nRF52840? nRF52840 doesn't support s332. Please use s340. See SDKs and SoftDevices Martix.

It seems you are updating the package to pca10040. Are you using s332_nrf52_6.1.1 for nRF52832DK (pac10040)? If so, you should use 0xBA for --sd-req. Please modify like this:

nrfutil pkg generate --application ble_ant_app_hrm_pca10040_s332.hex --application-version 1 --application-version-string "1.0.0" --hw-version 52 --sd-req 0x9B --key-file private.key app_dfu_package.zip

Hi

No, I am using an older version s332_nrf52_5.0.0

It looks like moving to 6.1.1 will cause some recompile issues as things seem to have changed in the .h files

Can I compile wit 5.0.0 and but use 6.1.1 ?

 No, it won't work.
