Including nRF5 SDK for Mesh functionality in an nRF5 SDK example

Aftab

Hello,


I'm integrating Nordic Mesh SDK into nRF5_SDK_15.2. I have following following guide for this:


https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v3.2.0%2Fmd_doc_getting_started_how_to_nordicSDK.html


After completing all the steps, the compiler shows following errors. I'm unable to locate the cause of error. It seems there are several constants related to
flash storage that are declared somewhere (or need to be declared). I'm not sure where they are declared or where to declare them. Can anybody please guide me?

    Glad that it worked for you. 

    We currently don't have the documentation or example on combining the proxy (and PB-GATT) role with the normal BLE application. But I don't see any reason it wouldn't work. You would need to follow what we have in the light switch example where we enable PB-GATT and Proxy feature in mesh. 

    Note that after we provisioned, we will reset the softdevice to enable proxy service. You may need to restore your service after the provisioning as well.

    Hello,

    I'm still working on the same project, this time for nRF52840 chip. I have modified the ble_app_template example and added mesh to it using this guide. I'm using Mesh SDK4.0.0 and nRF5 SDK 16.0.0, soft device version is v7.0.1.

    After including files in .emProject file and including user directories in the preprocessor section, changed section placement as below, project compiles successfully.

    Added mesh_main_initialize(); and mesh_main_start(); functions in the main.c file. The project compiles but debug port throws error: app: ASSERTION FAILED at :0

    If I comment out mesh_main_start(); function, the device functionality is as expected except mesh. Previously this error was also on mesh_main_initialize but I changed placement macro FLASH_PH_SIZE=0x100000 to FLASH_PH_SIZE=0x80000 and the assertion error was gone for mesh_main_initialize(). I think there is something to do with placement macros but I cannot figure out what to do.

    Also had to remove following lines from .emProject file to get rid of RTC1_Handle error.

    Hi Aftab, 

    Could you send your whole project folder ? So we can try here ? 

    Please make sure your Linker Option -> Section Placement File points to flash_placement.xml /xls file (not sure why you call it .xls file ? ) 

    If you test using our example inside \examples\sdk_coexist do you see the same error ? 

  • 0 in reply to Hung Bui

    I'm trying in the examples\ble_peripheral folder. I have adopted two approaches:

    1. Converted an S132 (with nRF52832 chip) co-exist project to S140 project (with nRF52840 chip)

    2. Took an nRF52840 template and added mesh to it.

    Both led to the same result with same error as reported above.

    Checked section placement file points to flash_placement.xml.

    I am attaching the project. I'm using Segger ES.

    "..\nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_template_mesh\pca10056\s140\ses"

    Hi Aftab, 

    I found that you have double defined MESH SOC OBSERVER. In main.c you declared:

    NRF_SDH_SOC_OBSERVER(m_mesh_soc_observer, MESH_SOC_OBSERVER_PRIO, mesh_soc_evt_handler, NULL);

    But it's already defined in  mesh_main.c . If you remove the one in main.c it should work. 

    I also saw an assertion inside sleep_mode_enter() when the firmware tried to enter sleepmode. Most likely you would need to disable mesh before you enter deep sleep mode. Have a look here: devzone.nordicsemi.com/.../reliably-disabling-mesh-stack-quickly-for-low-power
