implement the NCI 2.x initial sequence to support NCI 2.x NFCC.
Since NCI 2.0, CORE_RESET and CORE_INIT sequence have been changed.
If NFCEE supports NCI 2.x, then NCI 2.x initial sequence will work.
In NCI 1.0, Initial sequence and payloads are as below:
(DH) (NFCC)
| -- CORE_RESET_CMD --> |
| <-- CORE_RESET_RSP -- |
| -- CORE_INIT_CMD --> |
| <-- CORE_INIT_RSP -- |
CORE_RESET_RSP payloads are Status, NCI version, Configuration Status.
CORE_INIT_CMD payloads are empty.
CORE_INIT_RSP payloads are Status, NFCC Features,
Number of Supported RF Interfaces, Supported RF Interface,
Max Logical Connections, Max Routing table Size,
Max Control Packet Payload Size, Max Size for Large Parameters,
Manufacturer ID, Manufacturer Specific Information.
In NCI 2.0, Initial Sequence and Parameters are as below:
(DH) (NFCC)
| -- CORE_RESET_CMD --> |
| <-- CORE_RESET_RSP -- |
| <-- CORE_RESET_NTF -- |
| -- CORE_INIT_CMD --> |
| <-- CORE_INIT_RSP -- |
CORE_RESET_RSP payloads are Status.
CORE_RESET_NTF payloads are Reset Trigger,
Configuration Status, NCI Version, Manufacturer ID,
Manufacturer Specific Information Length,
Manufacturer Specific Information.
CORE_INIT_CMD payloads are Feature1, Feature2.
CORE_INIT_RSP payloads are Status, NFCC Features,
Max Logical Connections, Max Routing Table Size,
Max Control Packet Payload Size,
Max Data Packet Payload Size of the Static HCI Connection,
Number of Credits of the Static HCI Connection,
Max NFC-V RF Frame Size, Number of Supported RF Interfaces,
Supported RF Interfaces.
