Hi,

I'm trying the get a Redpine RS9116 module working with
networkmanager. 
I've tried this on 5.3, 5.5 and next-20200128. I'm using the Redpine
1.5 
"rs9116_wlan_bt_classic.rps" firmware.

If I configure the interface using iw, wpa_supplicant and dhclient
all 
works as expected.

If I try to configure the interface using nmtui most of the time no
APs 
show up to associate to. "iw dev wlan0 list" shows all of the APs in
the 
vicinity.

If I do manage to get an AP to show when I try to "Activate a 
connection" I get the error below

Could not activate connection:
Activation failed: No reason given

I suspect this is a driver bug rather than a NM bug as I saw similar 
issues with an earlier Redpine proprietary driver that was fixed by 
updating that driver. What rsi_dbg zone will help debug this ?

NM just uses wpa_supplicant underneath, so if you can get supplicant
debug logs showing the failure, that would help. But perhaps the driver
has a problem with scan MAC randomization that NM can be configured to
do by default; that's been an issue with proprietary and out-of-tree
drivers in the past. Just a thought.
