Hi,
I have an BCM4355 chip interfaced to SM32MP157 processor,both the drivers for WIFI/BLE are loading.But while running any operation on them I am facing issues.
WIFI Issues:
1.Both AP and STA mode are not running simultaneously at a time only AP mode is running.
2.If I run the wifi supplicant I was getting below errors

BLE Issues:
On boot up I am getting below prints w.r.t Bluetooth
Bluetooth: hci0: command 0x0c03 tx timeout
Bluetooth: hci0: BCM: Reset failed (-110)
If I run the bluetoothctl tool I was returning below error
bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available
Can anyone help me how to fix these errors for my module.Thanks in advance.

Srikanth.
