Secure bootloader ble with UART

[AP1]

HI currently  i am utilizing sdk ver 17.1.10  nrf52840 s140 we are using dfu/secure_bootloader/pca10056_ble app and i need to add UART app to it so that so we need both bootloader ble  advertiser and with UART added to it   currently we have added UART to it but whenever we call app_uart_put() function it was unable to advertise if we comment this function it is advertising as dfuTarg can you suggest me any steps to add uart to the secure bootloader /ble so that both peripheral can be utilized f it is possible NOTE: We referred secure bootloader /pca10056_uart  example but in this sdk it will not advertise so we need both advertiser + Uart 

[AP1]

1. in secure bootloader/pca10056_ble_debug sdk we need to add uart

2. For to tx the bin data to the other controller device

My question was not what your requirements are. They were plenty clear from the diagrams.

The question was: What do you need help with?

I already provide links with details on the current solution in the nRF5 SDK.

1. Hi i went through the links provided but i doesn't got much info to proceed further  i have attached files if you can tell us where it went wrong at least we can proceed further 

2. \..\..\nRF5_SDK_17.1.0_ddde560_ver_1.1\examples\dfu\secure_bootloader\pca10056_s140_ble_debug

3. we have added UART with wrapper function in nrf_dfu_flash.c file  and changes in the  nrf_dfu_utils.c file so that it can able to accept irrespective of size

I usually only start considering debugging projects after there have been substantial evidences showing that it is necessary. That is not the case here. You will need to tell me what you have done, and what is not working in more details.

If you need someone to help you with your project, we do have a list of Design Partners here: Design Partners - nordicsemi.com

I do not believe the links I provided you does not have information. Please go over discussions carefully, visit the links that the people provided. You will find references you can use in your implementation.

If you insist that it doesn't help, please answer these questions:

Have you tried the solution?
Can you explain to me in some details why the discussion there does not help?
What steps have you taken?
What is not working?

This is the only detail you have given me, and I must ask, why did you do that?

The size check is there for a very good reason: preventing new download from overwriting important data regions. If your downloaded binary does not pass the size check, that means the binary is too big.
