Renaming device

[Jonathan]

I'm trying to rename my device using s130, but the name doesn't get applied.

I went back to the "roots", ie the HRS sample.

Just before entering the loop, I add a name change:

advertising_start();

		ble_gap_conn_sec_mode_t sec_mode;

		BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
		char *name = "New name";

		err_code = sd_ble_gap_device_name_set(&sec_mode,
                                    (const uint8_t *) name,
                                    strlen(name));
		APP_ERROR_CHECK(err_code);
// Enter main loop.
for (;;)
{
    if (NRF_LOG_PROCESS() == false)
    {
        power_manage();
    }
}

And this name doesn't get applied, but it doesn't return an error code either.

Hi,

You will have to update the advertising data after setting the new name, if you want the new name to be visible when advertising. This can be done by calling advertising_init, or setting the advertising data directly using ble_advdata_set.

Best regards,

Jørgen

When calling advertising_init, it actually caused my device to stop advertising (I was calling it while a central is connected). I replaced with ble_advdata_set, it's now working. I don't know if it's an expected behaviour, but I wanted to document it.

It should not stop your advertising. You need to check any error codes in the advertising_init fuction, to make sure it is not returning any errors.
