Hello, I used s130, nRF5_SDK_12.1.0_0d23e2a, SoftDevice 8_9_0. Is there any example to study the central bond?
I use the examples->ble_central->ble_app_uart_c, the following is my code:
int main(void)
{
bool erase_bonds;
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, NULL);
uart_init();
buttons_leds_init(&erase_bonds);
ble_stack_init();
peer_manager_init(erase_bonds);
if (erase_bonds == true)
{
printf("Bonds erased!\r\n");
}
db_discovery_init();
nus_c_init();
whitelist_load();
printf("BLE Central Start!\r\n\r\n");
scan_start();
while(1)
{
power_manage();
}
}

When this BLE central connect to the BLE peripheral, It can't complete the bonding, I don't know how to bond, please help me, thanks
