Non-connectable advertisement while scanning as a Central

RE: Non-connectable advertisement while scanning as a Central

Did a quick test and saw no issues:

advertising_init();    //from ble_app_template example
err_code = ble_advertising_start(BLE_ADV_MODE_FAST);    //from ble_app_template example
APP_ERROR_CHECK(err_code);

nrf_delay_ms(5000);

err_code = sd_ble_gap_adv_stop();
APP_ERROR_CHECK(err_code);

advertising_beacon_init();    //advertising_init() from ble_app_beacon example
err_code = sd_ble_gap_adv_start(&m_adv_params);
APP_ERROR_CHECK(err_code);

As this discussion is not related to the original question anymore I suggest that you make a new question.

I wasn't clear. Start non connectable advertising -> stop -> start connectable advertising using ble_advertising_init/ble_advertising_start (your BLE Advertising library). The problem appears to be in using the library after manually initializing advertising data and params outside of the library (doesn't matter if the advertising is stopped in between).

You can't do connectable advertising and non-connectable advertising at the same time (using the SoftDevice). If you are going to do connectable advertising you have to stop non-connectable advertising first.

Alternatively you can do non-connectable advertising in timeslot. See the multiactivity example in the SDK for more detail.

I'm seeing issues when I try to use the ble_advertising module to enable "connectable" advertising after using sd_ble_gap_adv_start() to start nonconnectable advertising. Specifically, I get a hardfault when the ble_advertising_init() routine does its thing.

To do non-connectable advertising you should not use the ble_advertising module. You can use ble_advdata_set(..) to set the packet data and then start advertising with the SoftDevice call sd_ble_gap_adv_start(..). See the ble_app_beacon example for how to do this in more detail.

Yes, it is possible.

You can use ble_advdata_set(..) to set the packet data and then start advertising with the SoftDevice call sd_ble_gap_adv_start(..). See the ble_app_beacon example for how to do this in more detail.
