Channel index from advertisement when scanning in zephyr

[smackenzie]

Hello,

We are switching our firmware from the old sdk into the NRFConnect zephyr sdk and I cant see any way to retrieve the channel of the advert when scanning. We need this for machine learning powered positioning from advertising.

The original firmware used `ble_gap_evt_adv_report_t::ch_index` from ble_gap_evt_adv_report_t. Does zephyr have any equivalent in when using the nrfconnect sdk scan module?  

Thanks,

Sam

Hi Sam,

NCS advertising reports are limited to the information that is available in the LE(Extended) adv packet and there is no channel index in that event. BLE Core spec 5.2 Vol 4 part E, Section 7.7.65.13 ->LE Extended Advertising Report event.

To be able to give application more info about the channel index in adv_report we need to add a vendor specific event which is not in the roadmap as of now. If you want this support, then please talk to the Regional Sales Manager Wendell ( [email protected])
