[nrf54][sdk3.0.1]peripheral_hids_mouse keep showing "W: No buffer available to send notification"

[kai_ren]

I'm using nRF54L15 dk, SDK 3.0.1 and sample code: peripheral_hids_mouse

I made a few changes to send mouse pos.x every 15ms, but I kept seeing below error from terminal console, how can I enlarge buffer size? 

W: No buffer available to send notification
W: Unable to allocate buffer within timeout
E: Unable to allocate buffer for op 0x1b

Hi there Kai,

What is CONFIG_BT_ATT_TX_COUNT set to in your project config? Can you try to increase it?

Hi Jared, I have CONFIG_BT_ATT_TX_COUNT from 5 to 100, still could observer below happened. 

W: No buffer available to send notification
W: Unable to allocate buffer within timeout
E: Unable to allocate buffer for op 0x1b

Hi Kai,

What if you set  CONFIG_BT_BUF_ACL_TX_COUNT to 10?
