Hello,
I am trying to start WiFi mesh using this EVM and SDK 6.0.0.7 (Kernel 4.19.x).
Getting the error that "command failed: Operation not supported (-95)" when I attempt to start the mesh.
Gone through the previous discussion around this. Some of them are marked as "Resolved" without any details.
Some of them talks about old kernels (like 4.4, 4.14 etc).
Before debugging the WiFi driver, I want to make sure whether this kernel and other OS components supports WiFi mesh.
Please find below the details of my setup
Looking forward for the confirmation about this SDK WiFi mesh capabilities,
Thanks
