== Prepare ==
* Platform: nRF52840
* Board: PCA10059
=== SDK & Mesh SDK ===
* nRF5_SDK_15.3.0_59ac345
* nrf5SDKforMeshv310src

=== Toolchain ===
* gcc-arm-none-eabi-7-2018-q2-update-linux.tar.bz2
* export PATH=$PATH_TOOLCHAIN_BIN:$PATH

=== Cmake build ===
# cd nrf5SDKforMeshv310src
# mkdir build & cd build
# cmake -G Ninja .. -DSDK_ROOT=$PATH_OF_NRF5_SDK -DPLATFORM=nrf52840_xxAA -DBOARD=pca10056 <---for nrf52840

=== Programming ===
*If nrfutil fail, try more times!!!
* Create app package
** nrfutil pkg generate --hw-version 52 --sd-req 0x00 --application-version 1 --application nrf52840_xxaa.hex zip.zip
* Display package info
** nrfutil pkg display dfu.zip
* Program the package
* sudo nrfutil dfu usb-serial -pkg zip.zip -p /dev/ttyACM0
* Using tool "nRF connect" in windows is better

=== Touble shooting ===
* Lost provision
** erase provision data

<pre>
   .nrf_mesh_flash :
  {
    PROVIDE(__start_nrf_mesh_flash = .);
    KEEP(*(SORT(.nrf_mesh_flash.*)))   <<---------------------------remove, to allow section recycle 
    PROVIDE(__stop_nrf_mesh_flash = .);
  } > FLASH
</pre>

** program again, then, program back to original one

=== Light example ===
* program light_switch_client_nrf52840_xxAA_s140_6.1.0 + s140_nrf52_6.1.0_softdevice.hex
* program light_switch_server_nrf52840_xxAA_s140_6.1.0.hex + s140_nrf52_6.1.0_softdevice.hex
