/****************************************************************************/
I added codes in device_manager_peripheral.c
void dm_ble_evt_handler(ble_evt_t * p_ble_evt){ //skipping to the changed part
case BLE_GAP_EVT_AUTH_STATUS:
if (p_ble_evt->evt.gap_evt.params.auth_status.auth_status != BLE_GAP_SEC_STATUS_SUCCESS){
event_result = p_ble_evt->evt.gap_evt.params.auth_status.auth_status;
}
else{
if ((m_connection_table[index].state & STATE_LINK_ENCRYPTED) ==
STATE_LINK_ENCRYPTED)
{
m_connection_table[index].state |= STATE_BONDED;
if (m_connection_table[index].bonded_dev_id == DM_INVALID_ID)
{
//Assign a peer index as a new bond or update existing bonds.
err_code = device_instance_allocate((uint8_t *)&device_index,
&m_connection_table[index].peer_addr);
//Allocation successful.
if (err_code == NRF_SUCCESS)
{ /*...*/}
else
{
event_result = err_code;
// my added part
if(err_code == DM_DEVICE_CONTEXT_FULL){
err_code = pstorage_clear(&m_storage_handle,
(ALL_CONTEXT_SIZE * DEVICE_MANAGER_MAX_BONDS));
//err_code = dm_device_delete_all(m_handle_pointer);
//m_handle_pointer is an extern variable pointing m_app_handle in main.c
}
}
}
The code's content is if the number of bonds reaches DEVICE_MANAGER_MAX_BONDS,
it will delete every bond infos.
Although the example code is implemented to erase all bonds when
BOND_DELETE_BUTTON_ID is pressed before initializing variables, I want to erase all bonds
automatically regardless of the button press.
I tried both pstorage_clear and dm_device_delete_all.
Even though both returned err_code 0 (NRF_SUCCESS),
it seems that the flash hasn't been cleared.
After the number of bonds reaches DEVICE_MANAGER_MAX_BONDS and calls these functions,
nothing happens.
Is there something that I'm missing?
Does these functions returning NRF_SUCCESS has relations with
DM_EVT_DEVICE_CONTEXT_DELETED (or other MACROS) or the scheduler?
Edited : About callback
I'm debugging with J-link.
I set a break point here. After I call pstorage_clear, however, it doesn't
call dm_pstorage_cb_handler.
What could be the problem? Or did I misunderstand about "getting the callback from pstorage"?
