Suitable scanner for extended advertisement data

[johkan]

I am developing a beacon for nRF52832 and can see the beacon in nRF Connect for iOS when using the following setting:

adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;

However, when I change to 

BLE_GAP_ADV_TYPE_EXTENDED_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED I don't see the beacon. All SDK calls are successful and return 

NRF_SUCCESS.

Can it be that my iPhone 8 and/or the nRF Connect app (v 2.4.12) is at fault? If so, what would be a better scanner?

Regards,

Johan

Hi Johan, 

Not sure the issue is on the phone or your application.  

Can your phone scan the ble_app_rscs which uses advertising extensions? If so, you can modify the ble_app_beacon to use BLE_GAP_ADV_TYPE_EXTENDED_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED.

Are you able to see the beacon? If so, you can refer to our ble_app_beacon example to debug.

Hi Amanda,

Thanks for the answer. I tried the ble_app_rscs example but cannot see the device neither in my iPhone 8 nor in a "quite recent" Android Pixel phone using nRF Connect. If I change ble_adv_extended_enabled to false the device is visible on both phones though. I am using SoftDevice s132 v7.3.0.

An update: I believe it is a scanning issue as the power consumption suggests the device is indeed transmitting. The green curve is ble_adv_extended_enabled set to 'false' and the red is 'true'. Spacing is ~28ms which is consistent with what nRF Connect reads. Not sure about the static offset though but that is a later concern.

Hi, 

I cannot see adv extensions on iPhone 11 either. 

On nRF Connect android app, you can check the device info to see the device supports adv extensions or not. 

  

I can see the device with the (ble_app_rscs) extended advertisement on the Android Pixel.
