Migrating to SDK14

[Bjarke]

Hi, I am trying to migrate to SDK14.2 from SDK12.

I have succesfully migrated to SDK13, but I am seeing linker issues with 14.

The linker comes with the following errors: In function nrf_sdh_ble_evts_poll': ../../SDK14.2.0/components/softdevice/common/nrf_sdh_ble.c:273: undefined reference tonrf_section_iter_init' ../../SDK14.2.0/components/softdevice/common/nrf_sdh_ble.c:275: undefined reference to `nrf_section_iter_next'

also for function sdh_request_observer_notify sdh_state_observer_notify nrf_sdh_evts_poll nrf_sdh_soc_evts_poll conn_params_init

I have included the .c files in the makefile and the headers are in the include paths...

Makefile

I dont know how to continue.

Hi,

Add the file nrf_section_iter.c to your project to fix the undefined reference to nrf_section_iter_init and nrf_section_iter_next:

$(SDK_ROOT)/components/libraries/experimental_section_vars/nrf_section_iter.c

Please give the error messages you get for the other functions.

Thanks, I have added the .c to the makefile, and it compiles now. What I dont understand is that a "normal" part of the sdk is now placed in experimental folders...

BTW how to add code in the post without looking weird. And how to add multiple tags..

I found the issue,

With the new SDK 14, there is addional settings that needs to be set in the SDK_CONFIG, or optional app_config.

It was due to VS_UUID not being set.

I am seeing error 34 (0x22) GATT CONN LMP TIMEOUT after 40 sec(everytime).

I have tried to alter the MIN_CONN_INTERVAL from 10 to 50 msec. noluck I have tried to alter the MAX_CONN_INTERVAL from 100 to 500 msec. noluck

Any other suggestions?

Hi, You wrote it as resolved but I don't understand how you resolve the error 34 (40 sec)? I'm not sure to need to open a ticket. Thanks, David C.
