gap_inquiry_start from hid_host_demo never has rssi and name

Pico W SDK 1.5.1

I ported the inquiry from a2dp_source_demo to hid_host_demo and it does find some devices but weirdly none have names or rssi like they do in a2dp_source_demo. Any tips?

There are three levels of inquiry response. The basic one does have neither name nor rssi. Please check packet log. Maybe you need to enable higher levels with: hci_set_inquiry_mode(INQUIRY_MODE_RSSI_AND_EIR) See gap_inquiry which also stores device addresses in a list and does a remote name query if needed.

That's it, that's what the a2dp source demo uses too. It did the trick, getting a lot more names now. I'll look at gap_inquiry too, thanks for the tips.

I see now you meant to point me to that inquiry example rather than a function 🤦 Just tried it and that works great, could even fetch my Logitech K810 name using remote name query 🥳

Glad you got it working. What project are you working on?

You got it working, I'm just trying to understand how it works 😁

What project are you working on?

Mostly assessing the Bluetooth HID capabilities of the Pico W for various projects.
