Using UART1 for SDK and UART0 for Mesh

[Sama]

Hi,

I am trying to integrate UART and DFU serial from the mesh example.

What I did is:

1. Adding uart drivers and libraries into the DFU project.

2. Adding codes of uart into DFU codes. I changed the priority of the art to "LOW".

3. Editing the sdk_config to enable uart1.

4. Programming an nrf52840 devkit by softdevice, dfu application, device page, and a bootloader as the board connected to the pc.

5. Programing an nrf52840 dongle by softdevice, dfu application, device page, and a bootloader as the target device.

Once I enter the command to send a file it returns:

Upgrading target on COM3 with DFU package D:\Behine Niroo\Nordic\NRF Mesh\nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_blinky\pca10059\s140\ses\Output\Release\Exe\dfu_test.zip. Flow control is enabled.

Failed to upgrade target. Error is: Failed to establish connection

Possible causes:
- bootloader, SoftDevice or application on target does not match the requirements in the DFU package.
- baud rate or flow control is not the same as in the target bootloader.
- target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.
- if the error is ERROR_BUSY at the beginning of the DFU process,increase the value of PAGE_ERASE_TIME_MAX by few milliseconds.

What does make this problem? May this relate to the art codes I added?

I appreciate it if you advise me on this issue.

Hi Hung,

Thank you for your reply.

Here is the log you needed.

Any solution?

I look forward to hearing from you.

Hi,

Could you please advise me to solve this problem?

I am struggling with that too much time.

Hi Sama, 
Sorry for late response, I was on vacation. 
From what I can see it seems that you were calling the send message from a Thread level. Could you show how you call send message in your code ? 
Can you send a minimal code that show the issue so that I can test here ? Please try to keep it as minimal as possible so I can run on a DK here.
