CC2745R10-Q1: ECC key generation in GAPBondMgr_GenerateEccKeys()

Hello,

You will need to add BLEAPPUTIL_GENERATE_ECC_DONE event to your pairing event handler:

BLEAppUtil_EventHandler_t PairingPairStateHandler =
{
    .handlerType    = BLEAPPUTIL_PAIR_STATE_TYPE,
    .pEventHandler  = Pairing_pairStateHandler,
    .eventMask      = BLEAPPUTIL_PAIRING_STATE_STARTED |
                      BLEAPPUTIL_PAIRING_STATE_COMPLETE |
                      BLEAPPUTIL_PAIRING_STATE_ENCRYPTED |
                      BLEAPPUTIL_PAIRING_STATE_BOND_SAVED |
                      BLEAPPUTIL_GENERATE_ECC_DONE,
};

You can find this in the app_pairing.c file in the basic_ble project.

Hi,

Our project does not use BLEAppUtil.We are not using BLEAppUtil, but are instead trying to receive the ECC key generation completion notification (GAPBOND_GENERATE_ECC_DONE) using the GAPBondMgr callback function.
Adding BLEAppUtil would require significant changes, so we would like to avoid that. We are considering a method that can achieve this using only GAPBondMgr functions.

Step A: ECC Key Generation Does Not Complete

1. Register the callback function with GAPBondMgr_Register().
2. When the ICall event GAP_DEVICE_INIT_DONE_EVENT occurs, call GAPBondMgr_GenerateEccKeys().
3. The callback function is not notified of GAPBOND_GENERATE_ECC_DONE.

Step B: ECC Key Generation Complete

1. Register the callback function with GAPBondMgr_Register().
2. Do nothing when the ICall event GAP_DEVICE_INIT_DONE_EVENT occurs.
3. Connect via BLE, and when the ICall event GAP_LINK_ESTABLISHED_EVENT occurs, call GAPBondMgr_GenerateEccKeys().
4. The callback function receives a GAPBOND_GENERATE_ECC_DONE notification.

If ECC key generation completion notification is received solely through the GAPBondMgr callback function, is there a limitation that prevents ECC key generation from being completed if GAPBondMgr_GenerateEccKeys() is called immediately after GAP_DEVICE_INIT_DONE_EVENT occurs?
