NFC T4T Open/Close Write capability + Android Read Event without Restarting NFC

[jloliveira]

Good afternoon,

We are using NFC on nRF52840 (Type 4 Tag, SDK15.0.0, Softdevice6.0.0) to exchange some data and we would need to be able to do the following, please let me know if it is possible:

1- Open/close the write capability without the need to restarting the NFC interface, i.e., without the need to call nfc_t4t_emulation_stop followed by nfc_t4t_ndef_rwpayload_set / nfc_t4t_ndef_staticpayload_set (either with write ON or write OFF) and nfc_t4t_emulation_start. 

2- Write data to be read by an Android Smartphone that would trigger an NFC Read Event on the Android side while keeping the phone on top of the NFC antenna (i.e., without moving the phone away and back again close to the antenna) and without the need to restart the NFC.

Looking forward to your reply,

Thank you,

João

Hey joão,

I'm afraid I do not know myself, so I asked the developers, but I've not yet gotten a reply. I'll try to get an answer out of them ASAP :)

Cheers,

Håkon.
