About sdk14.2 52832 password pairing timeout

[June6]

Hi

I'm working on a password pairing project. You must enter the correct password to connect properly.  And This function can be normally implemented between mobile phone and slave module. When the phone wants to connect, a password pairing box pops up, and you must enter your password to connect properly. But now the password function is also in effect between the master and slave modules. According to the simulation, it is known that the connection is broken because the master module did not respond to the password and the pairing timeout evt is entered from the module. How can i fix this problem?

Thanks

The following code:

int main(void)
{
    ret_code_t err_code;
    memcpy(passkey,STATIC_PASSKEY,6);	
    m_static_pin_option.gap_opt.passkey.p_passkey = passkey;																	
    err_code = sd_ble_opt_set(BLE_GAP_OPT_PASSKEY, &m_static_pin_option);
    APP_ERROR_CHECK(err_code); 
}
