  I'm using the luckfox pico ultra w. Enabling Bluetooth via

  Code: Select all

  hciattach -s 1500000 /dev/ttyS1 any 1500000 flow nosleep&

  , as explained [1], allows me to pair and use Bluetooth headphones. However when doing so, the Wifi becomes unstable and unusable. It's still connected but the transfer rate is almost zero. Any SSH connection via wifi is laggy or disconnected.
  
  I tried Bluetooth `A2DP` (high datarate) and `headset` (low datarate). It's possibly related to BL and Wifi sharing the same 2.5GHz spectrum and the high bandwidth of Bluetooth Audio. Although I saw that BL/Wifi coexistence seems to be enabled in the kernel [2].
  
  Is there any way be able to use WiFi while being connected to a bluetooth audio device?
