How I can remove GATT service but not reset chip ?

[Giang]

Hi all, I use NRF52832.

I have a problem. I want when I connect to my chip and bond. After bond success, I insert new service. And when I disconnect from my chip, new service will be removed. This is to prevent others from reading my service. Now, I can insert new service but I can't remove service when I disconnect. But when disconnect, I don't want to reset entity chip. This is requirement.

So , Pls show me an solution !! Thank

Hi Giang,

Why do you need to remove the service? Wouldn't adjusting the security parameters do just as well?

Points to note:

• Other devices can only accesses your services once they have connected. 
• Service UUIDs are only included within the advertising packet if you specify it.
• As you are bonding you can restrict all connections to bonded devices /whitelist only.
• If you only allow one connection at a time then whilst a device is connected no others can read the data.

Thank for reply,

I can't add whitelist because my device accept any mobile connect to it. After 30s if not bond, my device will disconnect. But within 30s, others can see my services. And I don't want it. Only device can bond to my device, it is  posible see my services. So I think if I disconnect after bond, I have to remove service .

Can you show me How I can disable and reinit SD ?

I follow step for disable SD : 

err_code = sd_softdevice_disable();
APP_ERROR_CHECK(err_code);
sd_softdevice_is_enabled(&res);
if(res)
{
NRF_LOG_INFO("SD is disabled");
}
else
{
NRF_LOG_INFO("SD is enabled");
}

But It printf "SD is disabled" but my chip still advertising. Why ? And when I reinit SD by funtion ble_stack_init(); It return error NRF_ERROR_INVALID_STATE ,  m_nrf_sdh_enabled = true .

Thank
