Long range porting to SDK 15.3.0

[Vladimir RB]

I'm trying to run the https://github.com/NordicPlayground/nRF52-ble-long-range-demo on Fanstel modules with integrated AFE by Skyworks - BT840X(E) https://www.fanstel.com/bt840x-nrf52840-module-with-pa . They described the link more the 4 km!
The main question here - it's required to port long-range-demo to new version of SDK. I can't found manual howto do it, but I seen on some analogic questions that it's should works on same major version.
I see that some function moved from experimental to stable from SDK 15.0 to 15.3 so i changed the path in project configurarion. It helps, but i still got 2 errors:

'NRF_LOG_STR_PUSH_BUFFER_SIZE' undeclared here (not in a function); did you mean 'NRF_CLI_PRINTF_BUFF_SIZE'?
in definition of macro '_SELECT_ASSERT_FUNC'
in expansion of macro 'STATIC_ASSERT_SIMPLE'
in expansion of macro 'STATIC_ASSERT'
in expansion of macro 'IS_POWER_OF_TWO'
in expansion of macro 'NRF_RINGBUF_DEF'

expression in static assertion is not an integer
in definition of macro '_SELECT_ASSERT_FUNC'
in expansion of macro 'STATIC_ASSERT_SIMPLE'
in expansion of macro 'STATIC_ASSERT'
in expansion of macro 'IS_POWER_OF_TWO'
in expansion of macro 'NRF_RINGBUF_DEF'

I think it should be the project configuration question, but I don't understand how to fix it.

When the long-range-demo will work on SDK 15.3 it'll reuired to add some code to control AFE https://www.fanstel.com/s/BT840X_SKY66112-Codes.zip
i tried to run this code on SDK 15.0, but it required 15.3. So It's to port the example to new SDK.

Please help me with this demo configuration.

Hi,

Try to add this to sdk_config.h,

// <o> NRF_LOG_STR_PUSH_BUFFER_SIZE  - Size of the buffer dedicated for strings stored using @ref NRF_LOG_PUSH.
 
// <16=> 16 
// <32=> 32 
// <64=> 64 
// <128=> 128 
// <256=> 256 
// <512=> 512 
// <1024=> 1024 

#ifndef NRF_LOG_STR_PUSH_BUFFER_SIZE
#define NRF_LOG_STR_PUSH_BUFFER_SIZE 128
#endif

I replaced the file by new from 15.3
But them I got the new error:

C:\Nordic\nRF5_SDK_15.3.0_59ac345\modules\nrfx\mdk\ses_nRF_Startup.s: No such file or directory

I found similar startup code in \modules\nrfx\mdk but they have different name and structure.

So I think that much more differencies between 15.0 and 15.3 and it's need to going deeper.

Can you compile this project on your machine?

I did a quick port for the "peripheral_long_range_demo_kit" to 15.3, it compiles and runs, but I have not tested it:
peripheral_long_range_demo_kit.rar

Note that the demo on github is originally build based on the "ble_app_att_mtu_throughput" example, so if you need to port the central code as well, it might be an good idea to start with 15.3 ble_app_att_mtu_throughput example, and modify it based on a diff between 15.0 ble_app_att_mtu_throughput and 15.0 central_long_range_demo_kit.

Thank you, Sigur,
I will test it when come back from business trip.

The file is broken. I test it on some browswers.
Can you reload it, please?
