NFC NDEF message can not trigger a phone reaction

[dpin063]

Hi, First of all, appriciate all your hard work on tech supporting, this is my first ask in this forum. I m currently using developing nrf52832 on Zephyr , working on the NFC module, i have most take this repository(fw-nrfconnect-nrf) for reference.

basically used nrfx_nfct.c, nfc_ndef_record.c and nfc_ndef_msg.c to create a custom ndef message with 1 ndef record in,  My project status is now able to use IRQ to trigger the following NFCT status - field detected, field lost, tx start & end. i can tell from the uart log. 

but it never got the reaction from a android phone, quick question is : are those driver codes enough to trigger a bell on a phone when a nfc tag is detected. why the phone doesn't have any reaction.

Thank in advance

Hi,

If you are using only the native OS of the phone and expect it to react to the tag, I think it will only react to NDEF messages that it recognizes. If you are using a custom message, you may have to use a 3rd party app to read the tag content (for instance "NCF Tools" on Android).

Note that we do not provide support for Zephyr/NCS on nRF52 series at the moment, this is only supported for nRF91 and nRF53 series.

You can check how the NFC libraries are used in nRF5 SDK for reference.

Best regards,
Jørgen

Thanks for your reply, that help a lot, What do you mean by "Note that we do not provide support for Zephyr/NCS on nRF52 series at the moment", the whole repository is not for nrf52 series? can I use 'nrfxlib' and 'fw-nrfconnection-nrf' as external modules in Zephyr which can be configured by west.

You can use the modules as much as you want, we will just not provide technical support for any issues you are facing when using Zephyr/NCS on nRF52 series ICs.

when i use it as a external module with west tool, i put it in /modules/lib/, and do west update got the repo, When i do cmake in it failed: 

kconfiglib.KconfigError: /home/sasha/gitlab/modules/lib/fw-nrfconnect-nrf/subsys/bootloader/Kconfig:25: '/home/sasha/gitlab/zephyr/../nrf/subsys/partition_manager/Kconfig.template.build_strategy' not found (in 'source "${ZEPHYR_BASE}/../nrf/subsys/partition_manager/Kconfig.template.build_strategy"'). Check that environment variables are set correctly (e.g. $srctree, which is set to '/home/sasha/gitlab/zephyr'). Also note that unset environment variables expand to the empty string.

i dont think this error had anything to do with the nrf52 series, can you help me with that? i have checked 'Kconfig.template.build_strategy' this file is not showed in zephyr

We may be able to help you with that. I would recommend that you create a new question about this, as it is not related to the topic of this thread. That way, the answer may be easier to find and use by other users facing similar issues.
