How to change SDK_13.0.0.4 projects in order to use s140_nrf52840_5.0.0-3.alpha

Question

I'm using SDK nRF5_SDK_13.0.0_04a0bfd and compiling the example ble_peripheral/ble_app_hrs/pca10056/s140/armgcc using Eclipse Mars 2. 
 Flashing softdevice s140_nrf52840_5.0.0-2.alpha supplied with the SDK and then loading the compiled app works fine (light blinking and device advertising), but I need to use the new s140_nrf52840_5.0.0-3.alpha softdevice in order to test the long range functionality. 
 I have updated my linker script memory locations in the project from the original: 
 
 FLASH (rx) : ORIGIN = 0x22000, LENGTH = 0xde000 
 
 
 RAM (rwx) : ORIGIN = 0x20002620, LENGTH = 0x3d9e0 
 
 to: 
 
 FLASH (rx) : ORIGIN = 0x24000 , LENGTH = 0xdc000 
 
 
 RAM (rwx) : ORIGIN = 0x20002620, LENGTH = 0x3d9e0 
 
 I left the RAM the same since the release notes did not indicate an increase in RAM requirement. 
 After I flash the new softdevice using nRFGo Studio, and then the app, the app wont start up. 
 What else do I need to change to make this example work with the latest -3.alpha softdevice?

Hi, 
 The S140 5.0.0-3.alpha adds support for connecting directly on Long Range / LE Coded PHY, while with 5.0.0-2.alpha the initial connection was established with regular 1Mbps mode. 
 
 You can find a migration document, s140_nrf52840_5.0.0-3.alpha_migration-document , attached with s140_nrf52840_5.0.0-3.alpha that describes how to migrate to S140 5.0.0-3.alpha. 
 One of the first thing you need to do is to copy the header files found in s140_nrf52840_5.0.0-3.alpha_API\include 
to your SDK folder SDK_folder\components\softdevice\s140\headers . After that you need to apply the changes described in the migration document. You can also find a patch, sdk_diff.patch , in the ble_app_att_mtu_throughput_example_connecting_on_long_range folder, that shows you the changes needed in e.g. ble_advdata.c
