I'm trying to switch off the WiFi part of the chip (BCM43341) while keeping BT active. I've tried wwd_management_wifi_off but it seems it turns off too much so the BT stack also fails, immediately or after a short while.

Any suggestions?

Hello magnusb

If you want only BT but not WIFI then you can use wiced_core_init() instead of wiced_init().

Thanks for the suggestion! I think I tried it but I got into some other trouble. But I'll make another try and see where it leads.

The thing is, we don't simply want to use BT only. We want to have BT always on, and then turn on WiFi sometimes, but keep it off most of the time to save power.

Hello Magnus,

I have reproduced the issue by using wwd_management_wifi_off in hello_sensor snip and found that after wifi_off API the functionality of BT has be halted. I will raise this internally and let you know.
