outdated training_05_ble_security_example

I am trying to follow the security example training_05_ble_security_example_v1.1
This is outdated and some of the definitions/declarations of functions have not been updated on the PDF.

void default_app_on_tk_exch_nomitm(uint8_t connection_idx,structgapc_bond_req_indconst*param)
{
//uint32_t pin_code= app_sec_gen_tk();
//app_easy_security_set_tk( connection_idx, (uint8_t*) &pin_code, 4 );
app_easy_security_tk_exch(connection_idx);
}

在SDK 5.0.4

void default_app_on_tk_exch_nomitm(uint8_t connection_idx, struct gapc_bond_req_ind const *param)
{
// Generate the pass key
uint32_t pass_key = app_sec_gen_tk();

// Store 32-bit number to local buffer
uint8_t buf[sizeof(uint32_t)];
for (uint8_t i = 0; i < sizeof(uint32_t); i++)
{
buf[i] = pass_key & 0xFF;
pass_key = pass_key >> 8;
}

// Provide the TK to the host
app_easy_security_tk_exch(connection_idx, buf, sizeof(uint32_t));
}

app_easy_security_tk_exch has a new definition

custs1_att_db also is different, there are no write attributes(easy copy paste but hard to follow)

Thanks
