RE: Extended advertising and ios

Hi Tim,

I was not aware of any iOS specific requirements/recommendations for the advertising extension feature, nor was I able to find anything about it in the "Apple accessory design guidelines" document. Is there some other document or webpage that mentions these requirements?

I tested the speed and cadence example in addition to a modified version of the beacon example and I was able to discover data on the secondary channel in both cases. However, this was with an iPhone 11 pro max (ios 14.6) as I don't have an Xr here that I can test with.

Beacon example with adv. extension:

devzone.nordicsemi.com/.../ble_5F00_app_5F00_beacon_5F00_pca10040_5F00_with_5F00_s132_5F00_softdevice.hex

[quote user=""]1) In the adv_report why is the aux_phy = 0x00 even when secondary_phy = 0x02
2) The aux_offset is 1.0979s ios needs this to be less than 10ms how can I ensure this?[/quote]

These values don't appear to be valid. According to the API documentation, the "aux_pointer" member is only set when .type.status is set to BLE_GAP_ADV_DATA_STATUS_INCOMPLETE_MORE_DATA (is BLE_GAP_ADV_DATA_STATUS_COMPLETE in your screenshot).

Best regards,

Vidar
