Problems with BLE Mesh
Hello,
I am currently working on porting an application to the "SAMA5D27 WLSOM1 Evaluation Kit" that uses the ATWILC3000 chipset.
I'm using: Kernel: linux4sam-2020.04 i.e., kernel 5.4 WILC Firmware: 15.4 OS: Minimal Ubuntu 20.04 (from here https://rcn-ee.com/rootfs/eewiki/minfs/ubuntu-20.04-minimal-armhf-2020-05-10.tar.xz) BlueZ 5.54 for the mesh implementation
Wifi seems to work without issues. BT firmware seems to be downloaded and started correctly. When the mesh stack starts I can see (using btmon) it query the device for supported features and commands and it then starts LE scanning (successfully).
I can see LE meta data coming in so the scanning seems to work. Eventually my application determines that it is unprovisioned and starts advertising itself as an unprovisioned mesh node. Trying to enable LE advertisement results in a "Command Disallowed" status.
When querying the states supported by the device (hciconfig hci0 lestates) I can see that advertising while passively or actively scanning is not supported. Is this expected to work (i.e., I have the wrong firmware or driver) or is this simply not supported by the chip?
Some output from hciconfig. I've also attached output from btmon from the start of my application.
