Hello everyone,
I will try to be as clear as possible.
I am using Connman to manage my network interfaces and I am facing an issue when I try to connect to SSIDs that are emitted by multiple APs.
I am in a company network where there are multiple APs with the same SSID on different channels.
On channel 1 there is one AP but the channel is overcrowded so it is hard to connect ( I guess it is because of that, but anyway Conman does not manage to connect using AP on channel 1).
The thing is when I ask connman to connect to my SSID using conmanctl it will always try to connect to the AP on channel 1 and then fail and ask me if I want to retry, and if yes it will try to connect on channel 1 again rather than trying an AP on a different channel.
Here is a dmesg log showing the failure :

My question is : how can I force connman to try to connect to all APs with a particular SSID ?
EDIT : I am using Connman 1.30 and wpa_supplicant 2.5.
I hope I was clear enough and thank you for all your answers !
