Replace HRS to NUS in the NFC example

[MANGO]

Hi, I use

• PCA10040 V1.1.0 (nRF52832-QFAA)

• Keil uVision 5.21

• SDK 12.1 + S132 v3 (experimental_ble_app_hrs_pairing_nfc example)

• Nexus 5 (Android 6.0, this device cannot install Nougat)

I wish to replace the HRS stuff (sensor simulation and bonding which uses peer manager and fstorage) to NUS.

I don't want to store the central's information to the nRF52.

In this case, which part of the code should be replaced in the experimental_ble_app_hrs_pairing_nfc example?

Since I hold SDK 7 for too long, these new managers and other things take me a while to figure it out.

-Best Regards, Mango

Basically, what you need to change is to replace the hrs service files with the NUS service files. Remember to add the nus BLE event handler in ble_evt_dispatch(..) and remove the hrs event handler.
If you don't want to store bonding information, you should remove everything that has to do with the peer manager.

As you can see in the code, peer manager is not involved in the NFC part of the pairing process (OOB authentication key). m_oob_auth_key is used in nfc_ble_pair_default_msg_encode(..) and used during the pairing process in main.c (sd_ble_gap_auth_key_reply(..) ).
